In urban subway construction, shield tunneling is one of the main choices for tunnel construction. The large amount of waste muck produced by shield tunneling brings many challenges to the urban environment. The processes of muck dewatering, transportation and landfilling will have a great negative impact on the environment. As a kind of urban mineral resources, waste muck will occupy a large amount of land resources when it is used in landfills. If the TBM muck are recycled as synchronous grouting material, ecological brick raw material, roadbed filler, etc., the ecological environmental protection function of subway construction will be effectively enhanced.

KOSUN is a professional company that provides solid-liquid separation products and integrated solutions to solid waste disposal in the fields of energy conservation and environment protection, and focuses on development and services of complete technologies and equipment in sludge reduction, harmlessness and resource utilization. The sludge treated by KOSUN vertical centrifuge can be used as various resources in the following fields:
1. Agricultural resource utilization of sludge If the sludge is used for agricultural purposes, it has the advantages of low operating cost, low energy consumption and low investment, and the organic part in sludge can be converted into the modifier component in the soil, so this utilization way is taken as the most promising disposal method.
2. Building materials utilization of sludge
2.1. Cementitious materials utilization of sludge For sludge, it often contains more ash, especially in the treatment of sludge in wastewater by coagulation method, which contains a lot of Fe and Al components, and can be used as additives of building materials.
2.2. Sludge ceramsite For lightweight ceramsite, it is usually used as a flower covering material or as a concrete aggregate and roadbed.
2.3. Sludge brick Relevant researches show that sewer sludge can be used to make ecological bricks used in construction. This kind of brick is actually made by the following process: 10% sludge is mixed into the clay and then fired at 900°C, which can optimize the effect.
3. Animal feed utilization of sludge
Sludge contains lots of corresponding substances with many useful values, such as ash content ratio of 26.1% to 46.3%, fatty acids of 0 to 3.5%, and crude protein of 28.4% to 40.8%. Therefore, it can be treated as feed protein.
4. Sludge as fuel
The sludge itself is rich in organic matter. After low-temperature carbonization of sludge, the calorific value is equivalent to lignite, so the sludge can be used as fuel with a low calorific value.
If the sludge is not treated and is directly discharged into the environment, it will be seriously harmful to the surrounding environment. After the sludge is treated harmlessly, stabilized and reduced in volume, it can be used as a valuable resource in many fields.

On April 1, the drilling footage of the New Year’s production capacity of the No. 6 Gas Production Plant, Changqing Oilfield Company exceeded 100,000 meters, and the time to reach this length was 28 days earlier than the year of 2018.
In order to ensure the quality and efficiency of production and construction, as well as high-quality and rapid development, the No. 6 Gas Production Plant has continuously deepened geological research and promoted technological innovation. On March 6, the first analysis while drilling and deployment disclosure meeting this year preliminarily defined the overall plan for the annual production and construction deployment, and carried out the geological analysis while drilling according to the implementation effect, and timely optimized and adjusted the deployment. Up to now, a total of 27 additional coordinates have been deployed, 11 production and construction favorable zones have been implemented, and 339 effective coordinates have been prepared.
At the same time, relying on the special projects and key technologies of Changqing Oilfield Company, the “twice-drilling” technology and the “small borehole” test were actively promoted. On March 8, the gas well with twice-drilling technology in the Gaoqiao area was successfully drilled. The second section to the finished drilling only took 11.21 days, which was 30% higher than the drilling speed of a conventional well with the same depth.
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 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.
