Drilling Mud Treatment and Disposal Methods

With the continuous improvement of environmental protection laws and regulations, people’s awareness of environmental protection has been gradually enhanced. Drilling mud treatment and disposal during drilling has become the focus problem in the drilling industry. The purpose of drilling mud treatment and disposal is to reduce environmental pollution and to find a economically and environmentally methods.

There are many existing drilling mud treatment and disposal methods, but each method has its scope of application. It should be selected according to the geologic environment, hydrology, soil, drilling fluid composition and economy of the oil and gas field. Throughout the processing methods at home and abroad, drilling mud treatment and disposal methods including the following categories:

(1) Direct discharge method

Direct discharge method mainly applied to conventional freshwater drilling fluid.

(2) Landfill method

This is a more primitive approach and is mainly suitable for general freshwater-based drilling fluids.

(3) Dehydration method

This method used the chemical flocculation, sedimentation and mechanical separation and other strengthening measures to make the waste drilling fluid in the solid-liquid two-phase separation.

(4) Pit seal

This method is a special landfill method. It is recommended for toxic waste drilling fluid treatment and disposal.

(5) Annular space treatment method

The waste drilling fluid is injected through the borehole into the formation or safety formation of the oil and gas.

(6) Soil biodegradation method

Sprinkle the waste drilling fluid directly onto the soil surface and mix it into the soil with a soil tillage machine. This method is mainly applicable to the processing of freshwater drilling fluids and some oil-based drilling fluids that are easily biodegradable.

(7) Land cultivation method

Land cultivation practices require an open and relatively flat land and it should have surface conditions that prevent erosion.

(8) Closed loop system

The system is equipped with high-efficiency solid-control equipment that uses rigorous management tools to reduce the amount of fluid-borne waste discharged while drilling and emit only a certain amount of wet solids for land, sea and virtually all non-gaseous Dispersed phase drilling fluid system. Effluent wet-solid phase can be buried in-situ, diluted in land, paved, filled or centralized, and the liquid phase recycled and reused, which not only reduces the cost of mud treatment but also saves water resources.

 (9) Solid-liquid separation method

Solid-liquid separation technology is the solid-liquid waste drilling fluid separation, the discharge of liquid standards, solid-phase buried or reprocessing.

(10) Curing method

This method is add curing agent to the waste drilling fluid to make it solidified into soil-like solid material, and then landfill or used as building materials. (Editor:Kosun Lily.Wang)

Sewage treatment technology is facing new changes

Sewage treatment technology is facing new changes

Compared with the traditional sewage treatment plant, the concept of sewage treatment plant proposed four new goals, namely: sustainable water quality, energy recovery, resource recycling, environment-friendly.

Sewage treatment
Sewage treatment

After 30 years of rapid development, China’s urban sewage treatment has made great achievements. But along the way, there are some hidden dangers in China’s sewage treatment business. Due to the lack of sustainable development concept, leading to the industry’s shortsighted, extensive, chaotic and even inferior. China’s sewage treatment project urgently needs to base itself on national conditions and carry out a systematic exploration for the future. The company is located in:

Recalling the course of development over the past 100 years, sewage treatment has made tremendous contributions to improving the living environment and promoting the progress of human civilization. The activated sludge method invented in 1912, long-term and effective to curb the discharge of water pollutants, still plays an important role in the sewage treatment system. In the 1960s, the United States put forward the concept of “advanced waterworks in the 21st century” with advanced thinking. That is, raising the standard of sewage treatment to drinking water standard has a profound impact on the development of the industry.

As of 2013, China has built and put into operation more than 3,500 sewage treatment plants at the county level and above, with a total daily processing capacity of 140 million cubic meters, playing a key role in deterring the intensification of water pollution.

Sewage treatment is in a period of major changes, urban sewage treatment plants will be reduced from pure pollutants into resources, energy plants, related policies, standards, technologies, practices are widely and profoundly changed. And these are the new directions that China must pay attention to in the future development of sewage treatment.

China Sewage Treatment Concept Factory is not the focus of the general sense of the project, demonstration projects, more should be seen as China’s sewage treatment business under the current opportunities and challenges for the future to a systematic exploration. (Editor:Kosun Lily.Wang)

Light rail mud management and separation process

Mentioned the Light rail 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:

  1. Closed 2. Open

(2) according to the different principle of balanced excavation surface earth pressure and water pressure:

  1. Closed shield machine can be divided into:
  2. earth pressure type B. mud type
  3. Open shield machine is divided into:
  4. hand-digging B. semi-mechanical digging C. mechanical digging.

二, the Light rail 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.

mud separation system
mud separation system

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)

Prospects for Oil Sludge Management Equipment

With the promulgation of the new environmental law, the environmental requirements is getting higher and higher to the oil field, and free discharge of oil sludge will no longer be allowed.Oil Sludge Management is becoming a focal issue.

Oil sludge is oil mixed into the soil.It will be mixed together and become very difficult to deal with.Oil sludge mainly from two aspects: First, crude oil from the stratum to the ground and accumulated in all kinds of containers, large tanks and recycling pools and other ground facilities; Second, Oil sludge produced by oil wells operations.

oil sludge management
oil sludge management

Oily sludge is mainly derived from oil field mining and sewage treatment plant, in general, the sludge oil content is from 10% to 50%, moisture content is from 40% to 90%. The ultimate purpose of Oil Sludge Management is to reduce the harmful resources. The common oil sludge treatment methods are solvent extraction, incineration, biological, coking, oily sludge profile control, comprehensive utilization of oil sludge. The results show that the current methods for Oil Sludge Management have their own characteristics and scope of application. As the oil sludge composition is complex, there is no treatment that can treatment all types of oily sludge.

According to statistics, the size of the pollutant treatment market is between 100 to 150 billion yuan in each year,and according to roughly calculation,the investment of Oil Sludge Management equipment needs more than 150 billion.

Since 2007,Daqing Oilfield have built nine Oil Sludge Management station, the annual treatment capacity can reach 3.2 million tons,all the oil sludge had been treatment harmless. Changqing Oilfield build a Longdong oil field sludge treatment station in 2013 and used the physical and chemical combined methods, the oil content of the treatmented oil sludge is less than 2%, moisture content is less than 60%, while the crude oil can be recovered. Xinjiang Fengcheng Oilfield operating area using microbial agents to deal with heavy oil sludge and the test results is very good, sludge oil content from 15% down to 2% below after treatment. The current test has been reviewed by the company.
