Solubilization thinner

Abstract

The invention discloses a solubilized viscosity-reducing agent composed of constituents with weight percent as: 7-15% dithizone solution, 9-13% carbon tetrachloride, 7-11% hydrogen peroxide, 13-15% xylene, 7-11% treated hydrochloride, and water. It has high permeability and speed to come to crude thick oil zone, combine minim water by inorganic solution, disperse gum bitumen and wax in crude oil, and also increase dissolution speed by 2-5 times. This invention is high efficient and fit to low temperature, and saves energy and cost.

Description

Technical field: [0001] The present invention relates to a viscosity reducer for reducing the viscosity of petroleum crude oil, especially a solubilizing viscosity reducer which is applied in the process of petroleum crude oil extraction, transportation, refining, storage, etc. to rapidly reduce the viscosity of petroleum crude oil in the form of swelling from the center agent. Background technique: [0002] We know that petroleum crude oil mostly exists in the formation in the form of heavy oil, high-viscosity heavy oil is generally above 100,000 CP, and low-viscosity heavy oil is generally between 1,000 and 2,000 CP. Because the technical conditions of oil production require that the viscosity of petroleum crude oil should be below 1000CP, people must add a large amount of viscosity reducer (surfactant) to crude oil. At present, the viscosity reducing agents used in oil fields mainly use emulsification and viscosity reduction as the technical mechanism. The necessary cond...
