Indoor Study of Viscosity Reducer for Thickened Oil of Huancai

摘要

Liaohe oil field block 58 for Huancai, the efficiency of production of thickened oil is low, and the efficiency of displacement is worse, likely to cause other issues. Researching and developing an type of Heavy Oil Viscosity Reducer for exploiting. The high viscosity of W/0 emulsion changed into low viscosity O/W emulsion to facilitate recovery, enhanced oil recovery. Through the experiment determine the viscosity properties of Heavy Oil Viscosity Reducer. The oil/water interfacial tension is lower than 0.003 lmN·m~(-1), salt-resisting is good. The efficiency of viscosity reduction is higher than 90%, and also good at 180°C.
