摘　　要：为进一步探索深部调驱提高采收率技术途径,系统研究了深部调驱提高采收率配套的技术方法,包括水流优势通道识别技术、体系评价选择、调驱数值模拟、实施工艺及调整措施。以大港油田两个区块实施深部调驱现场试验为例,结合室内数模及物理模拟研究结果进行对比分析,结果认为:以SMG微球凝胶+交联聚合物连续凝胶+体膨颗粒为主体系、多项技术方法配套的深部调驱技术为高含水油藏提高采收率提供了技术途径,但此项技术需要和油藏相匹配。研究成果对陆上高含水砂岩油藏调驱提高采收率具有借鉴意义。In order to further explore the deep profile control technology for increasing the recovery rate,this paper systematically studies the supporting technology methods of the deep profile control technology for increasing the recovery rate,including the identification technology of the dominant channel of water flow,system evaluation selection,numerical simulation of the profile control,implementation technology and adjustment measures.Taking two blocks of Dagang Oilfield as examples,the comparison and analysis of indoor numerical model and physical simulation results shows that the deep profile control technology using SMG microsphere gel+crosslinked polymer continuous gel+body puffing particles as the main system and supported by a number of technology methods provides a technical approach for increasing oil recovery in high water-bearing reservoirs,but this technology needs to match the reservoir.The research results can be used as a reference to increase the recovery rate of onshore high water bearing sandstone reservoir.
