Studied the water shutoff method, witch pre-treatment formation with high concentration of polymer, optimize water shutoff parameters by means of perpendicularity test, including mass fraction of polymer, intake volume of polymer, injection rate of polymer and permeability. 研究了用高浓聚合物预处理地层的堵水方法,正交试验法优化了堵水参数,包括高浓聚合物质量分数、高浓聚合物注入量、注入速度和地层渗透率极差。
