Oil-based mud treatment device and oil-based mud treatment method

Abstract

The invention discloses an oil-based mud treatment device and an oil-based mud treatment method.The oil-based mud treatment device comprises a hammer mill, a solid waste treatment mechanism and a pyrolysis gas separation treatment mechanism, and the hammer mill is used for hammer milling and pyrolysis of oil-based mud to obtain solid waste and pyrolysis gas; the solid waste treatment mechanism is communicated with a solid waste outlet of the hammer mill and is used for crushing and discharging the solid waste; and the pyrolysis gas separation treatment mechanism is communicated with the pyrolysis gas outlet of the hammer mill and is used for separating oil and water in the pyrolysis gas. The oil-based mud can be pyrolyzed, the viscosity of the solid waste is reduced to prevent the conveying pipe from being blocked, and the oil in the pyrolysis gas is recycled to prevent the environment from being polluted.

Description

technical field [0001] The invention relates to an oil-based mud treatment device and an oil-based mud treatment method. Background technique [0002] In recent years, with the exploitation of shale gas and the large-scale exploration and development of deep-water oil and gas in the ocean, the use of oil-based mud has gradually increased due to its good rheology, lubricity, and small damage to oil and gas formations. The mud will produce aromatic hydrocarbons with toxins, which will cause chronic poisoning such as central nervous system anesthesia and hematopoietic system damage. How to deal with oil-based mud becomes a serious environmental problem. If it is directly discharged, it will inevitably lead to serious soil and water damage. Pollution accidents seriously damage the ecological environment and directly endanger human health. SUMMARY OF THE INVENTION [0003] The technical problem to be solved by the present invention is to overcome the defects of the prior art a...

Problems solved by technology

[0002] In recent years, with the exploitation of shale gas and the large-scale exploration and development of offshore deepwater oil and gas, the use of oil-based mud has gradually increased due to its good rheology, lubricity, and small damage to oil and gas layers. However, oil-based mud The mud will produce aromatic hydrocarbons with toxins, which will cause chronic poisoning hazards such as anesthesia of the central nervous system and damage to the hematopoietic system. How to deal with oil-based mud has become a serious environmental protection problem. If it is discharged directly, it will inevitably lead to serious soil and water pollution. Pollution accidents seriously damage the ecological environment and directly endanger human health
