Microscopic Displacement Mechanism of Ordinary Heavy Oil by Viscosity Reducer and Polymer Flooding
摘要
Abstract
Viscosity reducer and polymers system suitable for heavy oil of block Gudao-2 of Shengli oilfield were selected so that recovery and microscopic mechanism of viscosity reducer and polymer flooding were compared.The results showed that the ultimate recovery rate of water flooding was only 41.1% and after water flooding there was large presence of residual oil and the film and lump.The recovery rate of XJ and OP-10 viscosity reducer flooding after water flooding was increased by 18.67%, which mainly relied on transport of large oil particles after deformation and emulsification to reduce the flow resistance and boosting function of dispersed oil particles to oil film and stripping of the remaining oil by drawing.The recovery rate of AP-P5 polymer flooding after water flooding was increased by 18.55% by increasing the sweep area and the pull effect on the oil film and blind-residual oil,so polymer flooding compared with viscosity reducer flooding was more valuable.关键词
