March 21, the reporter learned from China National Offshore Oil Corporation (CNOOC)
that the Company released its 2018 annual performance report. CNOOC steadily increased
oil and gas reserve and production. The annual net oil and gas production
reached 475 million barrels of oil equivalent, and continued to maintain cost
competitive advantages. The main cost of barrel oil continued to decline year
on year, creating a record of five consecutive years of cost reduction. By the
end of 2018, the company’s net proven reserves reached 4.96 billion barrels of
oil equivalent, hitting a new record high, and the resource base for sustainable
development in the future will be more solid.
the next step, CNOOC has formulated a strategy for deepwater development in the
South China Sea. It plans to build a deepwater oilfield cluster in the eastern
part of the South China Sea in the next few years, and build the first 100
billion cubic meters deepwater gas field discovered by China in the western
South China Sea, and continue to increase investment in exploration and
development, deepen the potential of oil and gas resources in the South China
Sea, and enhance the comprehensive support capability of oil and gas.
The cuttings dryer is used to recover water-based and oil-based drilling fluids from the cuttings, reducing the liquid phase ratio of the cuttings to less than 40%.Drillings drying screen is a drilling fluid shaker used to recover liquid phase in well site.
During operation, the drillings dryer can be combined with any equipment of the solid control system, such as linear vibrating screen, sand remover and mud remover.After these equipment combinations are processed, the excluded solids are recycled through a linear vibrating screen with fine mesh cloth to recover the liquid phase adsorbed on the solid phase. All equipment combinations become the drilling fluid cleaning system, which is installed on the drilling fluid irrigation in a straight line with the main vibrating screen.
Application field of drilling cuttings dryer:
1. Used for various types of drilling mud, such as oil-based mud, water-based mud and drilling cuttings drying in line with mud

According to the requirements of drilling fluid field and customers, other products of kexun environmental protection can be used.
The International Energy Agency (IEA) estimates that fuel oil supply is expected to face an acute shortage before 2020 when sulfur limit for marine fuel is set due to upgrade in refinery and a decline in medium and heavy crude oil production. According to the new regulations of the International Maritime Organization (IMO), by January 2020, the highest proportion of marine fuel sulfur will be reduced from the current 3.5% to 0.5%.
The IEA says, since November last year, due to the OPEC and non-OPEC (such as Russia) production reductions, the global production of medium and heavy crude oil has dropped by 1.4 million barrels per day, reducing the residual fuel oil market by 500,000 barrels per day. In the fourth quarter of last year, global demand for residual fuel oil was 6.74 million barrels per day, declining by 2.2% year-on-year.
The IEA states that the reduction in global crude oil supply is narrowing the profit margin of complex refineries comparing with simpler ones, which in turn leads to the disappearance of advantages of complex refineries. The increasing strengthening of fuel oil cracking in the past five months has made upgrades less feasible.

Mentioned the subway mud management and separation equipment, we should first understand the classification of shield machine.
一, the classification of shield machine.
(1) According to if the excavation face is closed:
Closed 2. Open
(2) according to the different principle of balanced excavation surface earth pressure and water pressure:
Closed shield machine can be divided into:
earth pressure type B. mud type
Open shield machine is divided into:
hand-digging B. semi-mechanical digging C. mechanical digging.
二, the subway Subway mud management and separation process:
Mud-water balance shield machine is a device for mud-water separation in the shield. The mud is used to resist the water pressure, and earth pressure on the excavation face to keep the stability of the excavation face, and control the deformation of the excavation face and the foundation settlement. The mud film is formed on the excavation face to keep the water pressure effectively acting on the excavation face.
The management and separation process of KOSUN KD Series mud management system:
(1) Separation of most solid stones and clods by primary screening;
(2) After the first stage is separated, most of the large particles above 3mm are separated, the separated mud flows to the slurry tank, and then is pumped by the mud pump to the secondary cyclone for separation;
(3) The accuracy of secondary separation is in the range of 70-74μm. After the secondary separation, the slurry is again pumped to a three-stage flow separator for separation.
(4) Three-stage cyclone separation accuracy is in the range of 20 ~ 25μm, three separate mud flow back to the pulp pool;
(5) After the waste slurry is subjected to pressure-dependent separation by a filter press as required, the mud particles larger than 5 μm in the slurry are almost completely separated, and then the precipitate is discharged to meet the emission requirements. Through these 5 steps the mud particles and water are separated.(Editor:Kosun Lily.Wang)
At present, there are many manufacturers to product Pile Foundation Mud Management Equipment and slurry separation equipment in the domestic, but the municipal area Pile Foundation Mud Management Equipment manufacturers are less. KOSUN is one of a well-known companies who product slurry separation system.
Urban construction piling is the basis of municipal construction, Pile Foundation Mud is not allowed to discharge before treated. Otherwise, the harmful substances in the waste slurry will pollute the urban surface soil environment, that will seriously pollute urban water. The traditional method of Pile Foundation Mud Management is to discharge the mud into the mud pool or exposed to a designated area by drying, these treated methods, although are more economical, but the pollution problem is not completely resolved. Now a new generation mud management equipment used more and more widely in the municipal engineering. Pile Foundation Mud and Slurry separation system equipment was born, specifically for the municipal engineering mud treatment programs.
