Waste drilling mud non-floor type innocent treatment system and treatment method

Abstract

The invention relates to a waste drilling mud non-floor type innocent treatment system and treatment method. The treatment system comprises a detachable mud collection pool, a vehicle-mounted mud treatment device, a disposal site impermeable ground layer, an innocent solid phase temporary stacking site and a detachable treated mud recycling pool, wherein the collection pool and the mud recycling pool are of detachable structures, can be detached and transported at any time, can be mounted on the spot and are convenient to transfer; and the prepared submarine self-propelled mud pump can automatically walk in the mud collection pool, and a practical effect of rapidly and effectively taking the mud from the pool is achieved. According to the whole set of waste drilling mud treatment system, mud collection automation, vehicle mounting of the mud treatment device and control system integration are realized, and a composite impermeable membrane is laid on the treatment site, so that hazardous pollutants can be effectively prevented from permeating into the stratum. Therefore, the pollution problem of the waste drilling mud is solved in an all-around mode, and the effects of protecting the oil region environment and reducing pollutant discharge are achieved.

Description

technical field [0001] The invention relates to the field of oil field technology, in particular to a system and a treatment method for harmless treatment of waste drilling mud without falling to the ground. Background technique [0002] Mud is a kind of drilling fluid, which is a mixture of water, clay particles and various chemical treatment agents. Drilling waste mud refers to the unusable mud formed during drilling in oil and gas fields. According to incomplete statistics in some documents, drilling The water content in the waste mud is about 50%, the solid content is about 36%, the oil content is about 6%, and it also contains about 8% of other organic and volatile substances. The composition is extremely complex and polluting, which is extremely difficult to dispose of. Hazardous solid waste is bound to cause serious pollution if not effectively treated. At present, the waste drilling mud in many oilfield well sites is directly buried by digging pits without treatment...

AI Technical Summary

Problems solved by technology

For the treatment of waste mud, the method of sedimentation and burial in traditional dredging tanks is still used, which still pollutes the environment and cultivated land, which is not conducive to environmental protection and sustainable development, and also seriously restricts the smooth progress of oilfield drilling.
