摘　　要：针对水平井开发后期的出水问题,结合水平井完井及出水特点,提出了HWSO选择性堵水及ACP控水两个技术思路。研究以及矿场实践表明,对于出水层位不清,或出水层段不能封隔的水平井应用HWSO选择性堵水技术;ACP材料在强度等性能上满足环空充填的需要,可作为直接堵水、管外环空封隔的手段,辅助实现分采、地层注胶堵水等工艺。According to the water-out problem at the later period of horizontal well exploration,together with the well completion of horizontal wells and the characteristics of water out,two technical ideas are put forward,which include the selective water shutoff of HWSO and the water control of ACP.The research and the field practice demonstrate that the selective water shutoff technology of HWSO should be applied to horizontal wells with the unclear watered interval and with the water exit interval unable to be sealed and blocked.Then the research and practice also indicate that ACP materials,which satisfy the needs of annulus filling at the property of strengths,can be used as the means of direct water shutoff and annulus block outside the pipe,and thus help to realize the technology of separate production and injected water shutoff.
