Abstract

The invention relates to the technical field of oilfield development and production, in particular to a using method of a device for fully mixing a demulsifier and well flow substances in an ultra-short distance. The method comprises the following steps: injecting the demulsifier into a water-containing and natural gas-containing mixture to form a water-containing and demulsifier-containing liquidand natural gas-containing mixture, i.e., dissolved gas liquid; the demulsifier, the natural gas and the water are in the form of a gas-liquid-containing film in the dissolved gas liquid, namely, thedemulsifier and the natural gas are contained in the liquid film; the dissolved gas liquid is injected through an injection device; in the filling process, the liquid film of the dissolved gas liquidis broken; the demulsifier is uniformly released along with the natural gas wrapped in the liquid film through an air floatation process; and the demulsifier and the well flow substances with reducedgravity generate convection in the corrugated pipe compensator, are uniformly mixed and fulfill the aim of demulsifying. According to the invention, the mixing time and distance of the demulsifier and the well flow substances are shortened, the mixing efficiency is improved, and low investment, low operation cost, high cost performance and good economic benefit can be realized.

Description

technical field [0001] The invention relates to the technical field of oil field development and production, in particular to a method for using a device for fully mixing demulsifiers and well fluids within an ultra-short distance. Background technique [0002] Demulsifier is an indispensable chemical additive in petroleum exploration, petroleum refining, and sewage treatment industries. Its main component is surface active substances, which can destroy the emulsified liquid structure to achieve the purpose of phase separation in the emulsion. Crude oil demulsification refers to the use of the chemical action of demulsifiers to separate the oil and water in the emulsified oil-water mixture, so as to achieve the purpose of dehydration of crude oil, so as to ensure the water content standard of crude oil export. [0003] In well fluids such as crude oil, there are some solids that are poorly soluble in water. When one or more of these solids exist in an aqueous solution in a ...
