Problems solved by technology

Among them, although incineration, biochemical, coking and profile control technologies have done harmless treatment of oily sludge, they have not carried out oil recovery, which has caused a great waste of resources, so the main treatment methods promoted in the industry are Recycling Technology
Although the solvent extraction method realizes the recovery of petroleum resources, it is difficult to reduce the oil content in the sludge because of the huge amount of extractant used in the extraction process and the high cost of the extractant, which often requires repeated extraction operations to reduce the oil content in the sludge. Widespread use

Abstract

The invention discloses a waste oil-base drilling mud treatment system and method and belongs to the technical field of industrial waste treatment. The method is low in cost and requires simple equipment, efficient separation of oil, water and residues in oily mud can be realized, the method is applicable to recovery and harmless treatment of oil products such as waste oil-base drilling mud, tankbottom oily mud or other oily mud with higher moisture content, particularly to oily mud with higher oil content, the recovery efficiency of the oil products can reach 99%, and the method has economic, social and environmental benefits and is an improvement of the prior art.

Description

technical field [0001] The invention relates to the technical field of industrial waste treatment, in particular to a waste oil-based drilling mud treatment system and method. Background technique [0002] Abandoned drilling oil-based mud is a solid pollutant produced during oil and gas exploitation and drilling. Its composition is relatively complex, which is composed of clay, weighted materials, various chemical treatment agents, sewage, mineral oil, phenolic compounds, heavy metals and cuttings, etc. It is a complex multiphase system composed of leaching solution with high toxicity. With the exploration and development of my country's oil and gas fields, oilfield drilling produces a large amount of waste drilling oil-based mud every day, and a large amount of waste drilling oil-based mud exists in a colloidal and semi-solid state and does not change for a long time, occupying a lot of land , seriously pollute the environment. For a long time, the waste oil-based mud prod...
