摘　　要：七棵树油田SW802条带目前已投入开发近10年,跟同一油田邻区SW8条带及SW10井区对比,初产低,产量递减快,采出程度低,储量难以有效动用。为了找出制约SW802条带高效开发的原因,本文从储层、相渗特征、技术极限井距、及有效驱替系统建立等方面研究着手,找出制约SW802条带高效开发的原因为物性差、驱油效率低、启动压力高、井距大无法建立有效驱替系统。The SW802 block in Qikeshu oilfield has been put into development for nearly 10 years. Compared with SW8 and SW10 blocks in the adjacent area of the same oilfield, it has characteristics of low initial production, fast production decline and low recovery rate. It is difficult to effectively use the reserves. In order to find out the reasons that restrict the efficient development of SW802 blocks, through the study of reservoir, facies permeability characteristics, technical limit well spacing and establishment of effective displacement system, the reasons restricting the efficient development of SW802 blocks were determined,including poor physical properties, low oil displacement efficiency, high start-up pressure and large well spacing.
