Abstract

The invention relates to an oil mud demulsification dispersion pressure filtration agent and a preparation method thereof, and an oil mud treatment method, wherein the oil mud demulsification dispersion pressure filtration agent comprises 30-40 parts of water, 50-60 parts of a composite demulsifier, 10-20 parts of a flame retardant, 0.5-1 part of solid phase sodium hydroxide, 0.5-1 part of sodiumbicarbonate, 0.5-1 part of polyacrylamide, and 5-10 parts of a sulfur removal agent. According to the present invention, the agent mainly uses the comprehensive effects of the inorganic matters and the small molecular organic matters to perform demulsification dispersion on the high-sulfur-content gas field gathering and transportation batch processing operation oil mud so as to achieve oil-water-solid three-phase separation, wherein the solid phase naturally flocculates and sediments, the oil phase enters the water phase after the saponification, and the solid phase naturally settles throughthe pressure filtration, such that the problem that the batch processing oil mud cannot be subjected to normal pressure filtration is solved.

Description

technical field [0001] The invention belongs to the treatment technology of oil sludge, and relates to an oil sludge demulsification dispersing filter press agent and a preparation method and an oil sludge treatment method, especially for the oil sludge generated when diesel oil and corrosion inhibitor coating are used on the inner wall of the gathering and transportation pipeline of a high-sulfur gas field. Sulfur oil sludge (batch oil sludge) is a demulsification and dispersion pressure filter agent provided by the three-phase separation of oil, water and solid. Background technique [0002] During the operation of gathering and transportation pipelines in high-sulfur gas fields, complex organic matter from formations including bitumen, crude oil, formation water with high sulfide content, various types of corrosion inhibitors added during batch operations, pipeline sediments, etc. After physical and chemical reactions, deep emulsification, mixing, and aging, a paste-like ...
