Abstract

The invention discloses a water-based wax cleaning agent, and belongs to the field of oilfield chemistry. The water-bases wax cleaning agent is prepared via mixing of following raw materials, by weight, 3 to 10% of a polyether-type nonionic surfactant, 2 to 7% of tween-80, 2 to 6% of a wax crystal dispersing agent, 1 to 3% of an alkali, 1 to 5% of an antifreezing solution, 2 to 8% of a mutual solvent, and the balance a solvent. The water-based wax cleaning agent possesses advantages of common water-bases wax cleaning agents that relative density is large, application effect on high-water-cut oil-producing wells is excellent, application is safe, and no fire hazard is caused, and at the same time, the water-bases wax cleaning agent is capable of solving a problem of common water-bases wax cleaning agents that fluidity becomes poor in winter. The water-bases wax cleaning agent is capable of increasing speed of wax surface wettability alteration, and improving wax prevention effect. A preparation method is simple and convenient; and the raw materials are low in carbon content, and friendly to the environment.

Description

technical field [0001] The invention relates to a water-based wax remover, which belongs to the field of oil field chemistry. Background technique [0002] my country's crude oil is rich in wax, and most of the crude oil has a relatively high wax content. Most of the exploited crude oil contains more than 20% wax, and crude oil with a wax content of more than 10% accounts for 90% of the entire crude oil output. Wax usually exists in liquid form under formation conditions, but with the continuous drop of temperature and pressure and the continuous release of light components during oil production, the wax in crude oil is continuously precipitated and deposited around the well wall and conveyor system surfaces. Causes damage to reservoirs and reduces well production. At present, oil well wax removal technologies commonly used in oil fields mainly include mechanical wax removal technology, thermal wax removal technology, chemical wax removal technology, and microbial wax remo...
