Novel viscosity reducer for viscous oil

Abstract

The invention relates to a novel viscosity reducer for viscous oil, and the novel viscosity reducer is a chemical agent mainly used for viscosity reduction and cold production of viscous oil. The viscosity reducer disclosed by the invention has the advantages of convenience in construction, high viscosity reduction rate, low price and the like. Laboratory tests and field applications show that the viscosity reducer disclosed by the invention is applicable to conventional (borehole) viscosity reduction mining, oil layer viscosity reduction and the like of a viscous oil well and can be used for solving the problem of the oil layer blockage at an immediate vicinity of a wellbore caused by large viscosity of crude oil or micro-emulsion. In summary, the viscosity reducer is wide in applicable range and significant in effect and can adapt to the viscosity reduction of various viscous oil.
