摘　　要：孤南油田131块已进入高含水采油期,为了改善区块开发效果,提高采收率,调剖堵水是一项有效的工艺技术措施。针对该区块的油藏特征及开发现状,探索出了一套适合中低渗高含水期油藏的调剖工艺技术及方案,并在堵剂优化组合方面取得新的突破。确定了"调+堵+调"、"由远及近"的深部调剖思路,制定了"多轮次、多段塞"的施工方案。经过对该区块中131-2井组的2轮次调剖,井组累增油1600t,投入产出比1∶6,取得了显著的经济效益,区块的水驱开发效果得到明显改善,为孤南油田后期整体深部调剖提拱了宝贵的经验。Block 131 in Gunan Oilfield has entered into the period of high water-cut oil production,in order to improve the effect of development in the block,enhancing oil recovery,profile control is an effective technical measures.For the reservoir characteristics and development status,a set reservoir profile control technologies and solutions are explored,and the optimal combination of blocking agent achieves new breakthrough.Determine the deep profile control ideas of'profile control+water blocking+profile control''operating from distant zone to near zone,'are determined to develop an operation plan of'multi-round and multi-slug'.After two times a profile control in Wellblock 131-2,accumulated oil increment is 1600 t,input-output ratio is 1:6,and it achieves remarkable economic benefits.
