Treatment process of oil-containing mixture generated during petroleum drilling and oil extraction

Abstract

The invention belongs to the technical field of mixture separation and recovery processes, and particularly relates to a treatment process of an oil-containing mixture generated during petroleum drilling and oil extraction. A fluid mixture in the oil-containing mixture first flows through a condenser for preheating; after preheating, both the fluid mixture and a solid mixture in the oil-containingmixture are heated in a heating kettle through a feed port of a single-stage long-axis reaction kettle under the action of heat conduction oil, and an oil base is gasified and separated; the oil basegasified in the heating kettle is filtered through a distillation pipeline filter screen and then enters a two-stage condenser for heat dissipation and condensation, the condensed liquid-phase oil base enters a recovery tank to be collected centrally, and the rest of waste gas successively passes through a spray tower and an electrostatic smoke removal device and then is emptied; and the mixtureafter fully separating the oil base in the heating kettle enters a solid material cooling system through a discharging port of the heating kettle, the cooled mixture is bagged and collected, and the waste gas successively passes through the spray tower and the electrostatic smoke removal device and then is emptied. According to the provided treatment process, the oil-containing mixture can be separated and recovered quickly and efficiently.

Description

technical field [0001] The invention belongs to the technical field of mixture separation and recovery technology, and in particular relates to a treatment technology for oil-containing mixture produced in the process of oil drilling and oil production. Background technique [0002] In the process of oil drilling and production, a large amount of oil-based mud and oil-based mud cuttings will be produced. Oil-based mud and oil-based mud cuttings mainly contain solid phase, oil phase and water phase. The solid phase mainly comes from broken Debris, mud additives, stones and other sundries in the process of transportation, the oil phase is mainly diesel oil, white oil, bio-oil, mineral oil, etc. Part of the mud in oil-based mud and oil-based mud cuttings and the oil base adsorbed on the solid surface are important resources. If oil-based mud and oil-based mud in oil-based mud cuttings cannot be recovered effectively, it will cause serious damage to the regional environment. Se...
