Construction of low shear-anti agglomeration functional viscosity reduction system
Due to the cha racteristics of high density,high viscosity,and poor fluidity in reservoir conditions,heavy oil reservoirs are limited in effective development,with rapid de-cline in period production and low recovery rate.In addition,after the use of viscosity re-ducer with emulsification,the emulsion droplets of heavy oil tend to agglomerate during the flow process,greatly reducing their fludity.This study evaluates the viscosity reduction effect and anti agglomeration ability under low-speed stirring conditions,screens out a demulsifi-cation system with"low shearing and anti agglomeration"characteristics,and optimizes the best concentration of the main organic viscosity reducer in the mixed system and the best concentration of the mixed system,providing theoretical support for the efficient development of heavy oil reserves.
