发明名称 Method for removal of flow-restricting matter from hydrocarbon producing wells
摘要 A method for removing flow-restricting matter such as paraffin, asphalts, clays, scales, or gyps from production equipment and producing formation of and in the vicinity of an oil or gas well. The method uses a combination of solutions consisting of mixed solvents and additives such as detergents, surfactants and acids. The solutions are electrolyzed along with the hydrocarbon product of the well in an above-ground reaction chamber. The electrolyzed mixture of solutions and hydrocarbon product are reintroduced immediately down the well casing and into the well formation.
