Deep Study in Development Trend of Bettering Solids Control Efficiency

READ: It is well known both at home and abroad that perfect solids control equipment indicate scientific and sustainable drilling operations. Via continuous reformation and improvement within the latest decade, drilling fluids solids control equipment can now raise the drilling technical standards, reduce circulating system maintenance workload, quicken the drilling speed and lower the operational costs with remarkable efficiency.
It is well known both at home and abroad that perfect solids control equipment indicate scientific and sustainable drilling operations. Via continuous reformation and improvement within the latest decade, drilling fluids solids control equipment can now raise the drilling technical standards, reduce circulating system maintenance workload, quicken the drilling speed and lower the operational costs with remarkable efficiency.

Prior to 1970s, merely a very simple shale shaker was widely put into application in oil drilling industry, but its separation size was just 400 mm in the best-case scenario and the solid particles had to return to circulating system afterwards. Later on, it was succeeded by ultra-fine mesh shale shaker, cyclone desander, desilter, drilling fluids decanter centrifuge, vaccum degasser, mud agitator, mud mixing devices and relevant mud tanks, electric operation cabinet, etc., which aggregately weigh more than five tons and whose total electricity consumption count 300kW. They could keep the solid content under 5% and adjust the low-density property of drilling fluids based on the requirements.

It is no doubt that their appearance has brought about huge transformation in oil drilling industry, however, meanwhile, it also resulted in surge of maintenance, keep-up, operation workload and energy consumption. Therefore, it has very much concerned the professionals at home and abroad how we should simplify the equipment, decrease energy consumption and improve the reliability with no or least reduction of solids control system property.

According to the current developmental requirements, it has become a trend to simplify the equipment, decrease energy consumption and improve the reliability, for which we have envisaged to achieve by two phases. In the long run, it is a very risky and adventurous mission to study practicality one-phase method. Nevertheless, things usually develop from junior to senior, from simpler to more complex forms. It is the same to solids control equipment. Research in solids control technology will be primarily oriented to develop the system with better efficieny and lower expenses. In the short term, it will take it as a priority to develop multi-shaker system with over-capacity, high reliablity and good separation effects, to minimize desilter start-up time and even to exclude desilter from the whole system. Guided by the goal, KOSUN will make continuing contributions by production of more equipment in the foreseeable future.

Why Do People Attach Increasing Importance on Solids Control Equipment?

READ: The latest development of drilling technology increases its demands on the performance of drilling fluids. It has been proved that it takes a complete set of suitable solids control equipment to improve that via contolling the solid content in drilling fluids, which guarantees the good performance of drilling fluids for a long time.

In terms of functions, drilling fluids can be categorized into such two groups as useful solids, which contain barite, chemical agents, bentonites, etc. and harmful solids, for instance, drill cuttings, coarse bentonites, silt, etc. Drilling solids control is defined as the technology used to fulfill the demands on the performance of drilling fluids by removing the harmful solids and keeping the useful solids.

The latest development of drilling technology increases its demands on the performance of drilling fluids. It has been proved that it takes a complete set of suitable solids control equipment to improve that via contolling the solid content in drilling fluids, which guarantees the good performance of drilling fluids for a long time.

All of the drilling operators wish to own premium drilling fluids since it can enhance drilling facilities and allow them to drill fast and safely. Mere chemical treatment cannot ensure a stable performance of drilling fluids, though at a considerable cost. It will also take effective mechanical treatment equipment to control its solids content ( in fact, water usually works together with mechanical treatment for better effects ). Thus, mechanical solids control is both an essential process in mud performance maintenance and a constituent of normal drilling technology.

In drilling fluids, the solid particles exerting greatest influence on its performance and mechanical drilling speed are mostly more than 15μm in diameter. They account for 70% of all solid phase. It is popular pursuit that effective mechanical equipment can remove them at any time.

It is an important measure to apply solids control equipment in optimization of well drilling. And it is necessary for scientific drilling to well control the solid content in the mud. Proper solids control can protect oil/gas bed, decrease drilling torque and friction, reduce the pressure wave of annulus pumping, prevent sticking caused by differential pressure, increase drilling speed, extend service life of drilling bit, minimize abrasion on equipment and tubes, prolong the lifespan of wear parts in drilling fluids circulating system, stabilize the boreholes, improve casing conditions, lessen environmental pollution, lower the expenses on drilling fluids, etc. Statistics show that 1% decrease of solid content ( that is, drilling fluids density reduce 0.01 ) in the mud will result in the increase in soft soil mechanical drilling by 8% or so. Accordingly, it will bring remarkable benefits if solids control is well performed.

In a word, people become increasingly aware of the significance of solids control equipment since it has directly influenced the safe, excellent and efficient drilling as well as protection of oil/gas bed.

Efficiency Analysis on Solids Control Equipment Removing Harmful Solid Phase

READ: It is necessary to carry out regular efficiency analysis of solids control system in drilling site in orde to improve drilling fluids properties and better manage the cost. Generally speaking, the aggregate drilling fluids consumption in a well counts 10 to 20 times the volume of a borehole. 

It is necessary to carry out regular efficiency analysis of solids control system in drilling site in orde to improve drilling fluids properties and better manage the cost. Generally speaking, the aggregate drilling fluids consumption in a well counts 10 to 20 times the volume of a borehole. That means 90% of the expenses are poured into volume and property maintenance of the additionally concocted 90% drilling fluids. However, it can give birth to remarkable economic benefits if solids control equipment is promptly adjusted to remove more “harmful solid phase”.

The efficiency analyses conducted on different equipment show that, theoretically speaking, all of them should have been taken away, but in fact only 80-85% or even lower amount of them have been removed and 90% would have been the best. It is also shown that, by a deeper study into separation capability of various solids control equipment and size distribution in such useful solid phase as barite and harmful solid phase(low-density particles), desander and desilter are not ideal choices to treat barite-weighted drilling fluids, but the decanter centrifuge can decrease the low solid phase gradually accumulated in any type of drilling fluids.

“Communique on Drilling Fluids Treatment Equipment” well elaborates the standard application methods and analysis approaches of various solids control equipment, for example. drilling fluids shale shaker ought to be analyzed in terms of its solids removal rate, cuttings removal rate and drilling fluids loss ratio; desander, desilter and drilling fluids decanter centrifuge ought to be analyzed in terms of solids removal percentage, low-density solid phase discharge velocity and barite discharge speed; the decanter centrifuge also need to be calculated on its barite recovery percentage, etc. 

Besides, another formula can also work on the calculation of solids control efficiency, such as, if the figures like, dilution volume per unit time, the formation volume and the max. cuttings content got from solid phase analysis are given, we can have the efficiency rate of solids control equipment. 

Is the Big Wild Goose Pagoda Launched?

Photo contrast of Xi’an tourist attraction---Big Wild Goose Pagoda on Oct. 24th when it was sunny and clear and on Dec. 18th shrouded in heavy haze.

On Dec 20th, a composite photo stringed by anonymous netizens caught many people’s eyes. It was a composite photo produced by putting two photos of Big Wild Goose Pagoda taken on different dates, displaying a huge contrast before and in haze. On Oct. 24th, the famous Xi’an tourist attraction could still be clearly seen on the photo with some grey buildings hundreds of meters behind it, however, on Dec. 18th, it was totally veiled by the pollution haze as if artificially erased from the landscape. The photo was amusingly surprising, but at the same time it also evoked the hazy Xi’an we have seen in recent months.

Ever since October last year, this ancient city, once glowing with profound historical heritage and colorful cultural corners, has been greyed by the toxic haze. Masks in citywide pharmacies are sold out and continuously out of stock. Heavy haze turns into a great barrier for smooth traffic and brings about a huge risk against citizens’ safety and health.  

In last December, air quality index soared sharply from 99 on 16th to 278 on 17th, 494 on 22nd and 500 on 25th, and finally settled itself down around the level of “Gravely Contaminated”. 

Days after the photo sensation, another group of composite photos followed suit by put in line the similar scenes on today’s Xi’an snack streets, crossroads, public squares and of the London life in the last century, which bore remarkable resemblance.

Environment pollution primarily results from unsustainable and excessive urbanization. In recent decades, China has been processing on a rapid development road. The governments have consecutively bolded “urbanization” on their agendas. However, successful and beneficial urban development relies on harmony and balance between human society and natural ecosystem. The fact is that speedy urbanization has been shattering our complete and once peaceful nature bit by bit. Nowadays, it has been transformed to a landscape ragged and spotted. 

In 2012, “On Economic Problems” published an article co-authored by Liuchi, renowned lecturer from School of Economic SCUEC and Zhong Shuiying, professor of economics from Economic and Business School of Wuhan University studying relationships between urban development and urban environment pollution. It illustrates the intimate correlation and reciprocating impact between them as well as the contradictions arising from slow environmental technology improvement and industrial structural adjustment. 

Heavy industry plays a significant role in promoting urbanization. Such industries as refinery, oil & gas exploration, petrochemistry contribute to great convenience in human life, but they also bring severe pollution to us. At the meantime, their advances demand more from power supply companies, which will exhaust more contaminants. 

Besides, urbanization expands cities in space, thus prolonging citizens’ daily commuting time and increasing exhaust emission from both private cars and public transportation. The increasing population migrates into cities. To some degree, it deteriorates the consequences above. 

Even though measures have been taken and regulations implemented, incomplete environment protection mechanism remains impotent and ineffective. China’s geological disadvantages further hinder environmental reformation. 

Accordingly, it is imperative for us all to stand against the haze and pollution with practical, effective and scientific measures. Sustainable development will not only satisfy present human needs, but also lead to human sustainability in the long run. Enterprises should all devote to sustainable development in order to erase the grey veil from sky, turn the filthy rivers clear and clad the earth with green coat again.

This meant that Xi’an KOSUN Machinery Co., Ltd. has got the “Green Permit” into international market.

On Dec 13th, KOSUN smoothly passed the in-situ auditing of ISO14001 Environmental Management System and OHSAS18001 Occupation Health Safety Management System Certification conducted by Baer International Certification Center. This meant that Xi’an KOSUN Machinery Co., Ltd. has got the “Green Permit” into international market.

Certificate of ISO14001 Environmental Management System

ISO14001, called ISO14001 Environmental Management System Certification in full, mainly defines the conformity assessment performed by a third-party certification organization based on ISO14001 standards. It is the standards issued by International Standardization Organization and subject to ISO14000 standard family. It was originally issued in 1996 for the first time and was reviewed by ISO(International Standardization Organization) in 2004. Its newest version is ISO14001-2004.

Certificate of OHSAS18001 Occupation Health Safety Management System

ISO14001 can be used in any organization, including enterprises, institutions and relative government units, to prove that its management has reached the international level, to serve as an assurance of its processes, products and control of various contaminants complying with relevant requirements and to help it set up a good company profile in society. KOSUN’s success on ISO14001 standard auditing can effectively build up its image, raise its visibility and help itself get the “Green Permit” into international market.

Occupation Health Safety Management System (OGSMS for short) is the modern safe production management mode starting up worldwide in late 1980s. and is called “post-industrialized management method” together with ISO9000, ISO14000, etc. Occupation Health Safety Management System was mainly derived from the requirements put on the enterprise development. Enlargement of enterprise scale and the increase of production intensification resulted in higher requirements on enterprise quality management and business mode. Therefore, entgerprises should adopt modernized management mode to make all the production and operation activities including safe production management scientific, standardized and institutionalized.

Occupation Health Safety Management System serves as a scientific and effective management method to improve enterprises’ operational health and safety achievements. It is quite useful in facilitating the implementation of operational safety regulations and systems, in turning the mandated operational health and safety management voluntary and in increasing the level of operational health and safety management. Besides, it is also very helpful to offset the direct or indirect economic benefits brought about by trade barriers. KOSUN’s success to get OHSAS18001 Certification from Baer International Certification Center signifies a worldwide recognition of its brand image and management level.
