Coalbed methane drilling mud t
Coalbed methane refers to the gas that is self-generated and stored in the coalbed, and its composition is mainly methane, so it is also called coalbed methane gas (CBM for short). CBM is a kind of clean energy and has great utilization value, especially under the severe situation of the current rapid development of international and domestic economy, increasing shortage of energy, environmental pressure and safe production of coal mines, the effective and rational exploitation of CBM is more urgent. with important. In recent years, many countries have used different mining technologies to mine coalbed methane, and have achieved remarkable results.
In the process of exploration, development and utilization of coalbed methane, a large amount of drilling wastewater and drainage wastewater will be produced, and these wastewaters are characterized by high salinity, high salinity, and a large amount of suspended solids. Into the nearby area, it will cause changes in water quality within a certain range, affecting the local industrial and agricultural production and residents' lives; if it is directly injected back into the ground, the produced water with high salinity and high salinity will easily pollute the underground freshwater layer.
In order to protect the environment and reduce the environmental pollution caused by the development of coalbed methane, the coalbed methane drilling sludge treatment system was developed. The sludge treated by the coalbed methane drilling sludge treatment system can be harmless, and the treated wastewater can be To meet the emission standards, it can be directly discharged or recycled.
The coalbed methane drilling sludge treatment system mainly includes: a mud tank, the feeding port of the mud tank is connected with the drilling sludge pipeline, and the sludge discharge port of the sludge tank is connected with the sludge inlet of the screw stacker through the pipeline, The sludge discharge port of the screw stacker is connected with the harmless treatment equipment through pipes. The sewage discharge port of the mud tank and the sewage discharge port of the screw stacker are connected to the water inlet of the sewage tank through the sewage pipe. The drainage of the sewage tank The outlet is connected with the water inlet of the coagulation and sedimentation tank through the pipeline, the water outlet of the coagulation sedimentation tank is connected with the water inlet of the contact oxidation tank through the pipeline, and the water outlet of the contact oxidation tank is connected with the water inlet of the secondary sedimentation tank through the pipeline. The water outlet of the sedimentation tank is communicated with the water inlet of the filter through a pipeline.
All units of the new coalbed methane drilling sludge treatment system produced by our company are assembled by skid-mounted, which is convenient for transportation, flexible and reusable. By adding a small amount of sludge back through the coagulation-settler, the sedimentation rate of the sludge can be accelerated, the amount of coagulant added can be reduced, the investment cost and the operating cost of the subsequent raw materials can also be reduced. The processing process (except dosing and sludge transportation) is automated, and there are few personnel on duty. Our drilling sludge treatment equipment conducts harmless treatment of the discharged sludge, and the treated water can be recycled or discharged.
