摘　　要：针对非均质多储层或非均质厚油层油田,在注水开发过程中,注水井吸水剖面和产液井产液剖面的不均匀性,从调剖堵水前后地层流体渗流特性的变化出发,提出了一种新的残余阻力系数确定方法,用来计算调剖堵水时的处理半径以及最佳处理液用量。该方法对矿场调剖堵水处理具有较大的指导意义。According to the characteristics of the oilfield with heterogeneous multiple or the heterogeneous thick reservoirs, during the process of waterflooding, unhomogeneity exists between the water injection profile of water in- jection well and the production profile of liquid producing well. Starting with the changes of seepage characteristics of formation fluid between pre-and post profile control and water shutoff, a new determination method of residual re- sistance factor to calculate treatment radius and optimum account of treatment liquid about profile control and water shutoff was proposed. This method has fairly good directive function to the profile control and water shutoff in field.
