摘　　要：QL复杂断块油藏目前已总体进入中、高含水开发期,剩余油分布更趋复杂。从影响剩余油分布的静态参数(地质因素)出发,根据储层沉积相带及其岩性、物性、非均质性、构造和砂体分布形态等建立流动单元的地质模型,准确、合理地划分出流动单元。结合动、静态资料,研究了不同流动单元的水驱油特征与水淹模式,对水淹后油气水分布规律进行了重新认识。在此基础上,研究了不同流动单元剩余油的分布规律,指明了挖潜上产的有利区域,指导油田挖潜实际效果显著。对同类复杂断块油藏高含水期剩余油挖潜,提高原油采收率具有一定的借鉴作用。At the present,QL complex faulted-block reservoir has come to the producing stage with middle to high water cut.There is more complicated remaining oil distribution.The geological model of flow units is set up based on sedimentary facies belts,lithologic,physical properties,heterogeneity,structure and the shape of sand body distribution by firstly considered the static parameters(geologic factors) infelicity the remaining oil distribution,the flow units are reasonably and accurately delimited.The water displaying oil characteristic and flood out pattern in different flow units are studied by combing dynamic and static data,the distribution law of oil,gas and water after flooding out is re-recognized.On the basis of that,the distributing law of remedies oil in different flow units is studied and the favorable regions for enhancing recovery are figured out,remarkable results are achieved.Chancing remains oil recovery in the complex faulted-block reservoirs in high water cut stage can take the method as reference.
