How to reduce cost and pollution in waste drilling mud treatment?

Pub Date:Jan 12, 2023    |    Views:128    |    

(1) Good Slurry treatment.

Slurry treatment includes: re-use, redirection of specific functions to exclude sources of contamination. The mud should be handled so that it can be injected into a safe zone or annular well. In the development of high-tech in the new era, the treatment technology of oilfield mud treatment in my country has also been upgraded and developed. The main technologies include MTC treatment, pit sealing and sealing, metal repair, solid treatment and optimization of solid treatment process. Effective treatment of drilling mud according to the state of oil drilling mud can improve the quality of oil drilling operations and reduce pollution damage to the environment. Among them, various remedial measures should be prepared for different types of excavation. The specific operation is: the clear water discharged from the bottom excavation can be directly treated. This method of injecting a safe or disinfectant is expensive and not commonly used. MTC cementing technology is a new type of technology that mainly deals with boiling water. It can be converted into cement liquid by adding curing agents and chemical reagents to reduce cement costs and reduce environmental pollution.

(2) Mud treatment system and mud recycling process strengthen decision-making.

Proper and efficient use of mud treatment systems enhances the treatment and discharge of toxic and dirty mud. When drilling in oil fields, please use transparent concrete adhesives to protect groundwater, reduce or eliminate groundwater pollution, and prevent damage to water resources. Improve inspection of construction or use as few chemical additives as possible. When preparing drilling fluid, the amount of additives must be controlled and the amount of toxic and harmful additives must be strictly controlled. Second, a four-step cleaning process should be performed using a closed-loop circulation system to avoid loss of fluid volume due to frequent water intake and dilution of the fluid surface. For the specific construction process reduce the amount of medicine used and minimize the amount of drilling to prevent wasting liquid waste after drilling is completed. At the same time, sludge is recycled and used to reduce costs and pollution.

(3) Modify the manufacturing process and optimize the molding model.

In the process of oil field drilling, the construction supervisor should modify the phase of excavation work that causes environmental pollution when the production process is performed, using a combination of discrete sources and cluster paths to save site usage. Minimize damage to landform projects and impact on land use. The construction process is combined with the cassette, which refers to the depletion of several wells in a single well to reuse mud, reduce waste generation and enhance wastewater treatment from drilling, etc., and reduce the transmission of oil in the natural environment Saturated mud from waste. The second is to develop the ability to control excavation and drilling mud. A specific method currently in use is the use of a drilling fluid that compresses the sediment flow to inhibit the formation of sediment during drilling and reduce the increase in sediment volume during excavation.
