摘　　要：PCS调驱工艺技术是一种将调剖堵水与三次采油技术有机结合起来的技术。在室内实验成功的基础上,针对马寨油田的油藏条件筛选出最佳的驱油剂配方,在马寨油田W95块、W305块进行先导试验。试验证明,PCS工艺技术有一定增油潜力,PCS调驱过的井组自然递减,综合递减远远小于整个区块递减,收到较好的控水稳油效果,取得明显的经济效益。PCS (profile control-surfactant) technology combines profile correction and water plugging with tertiary oil recovery. Based on successful laboratory experiments, optimal oil displacement agent formula that was selected in view of the reservoir conditions in Masai oilfield was used to perform pilot study in Block W95 and W305. Pilot results revealed that the natural decline and composite decline of well groups where PCS had been performed were far less than that of the whole block. Relatively good water-cut control and production stabilization effects were achieved and the economic benefits were remarkable.
