摘　　要：吴仓堡油田地处鄂尔多斯盆地伊陕斜坡中段属吴起三角洲前缘组成部分。在钻探过程中通过地层对比研究、岩心分析、试油测试等发现了吴仓堡油田长9油藏储层平均孔隙度为8.0%,平均渗透率为0.23×10-3μm2,孔喉半径小、油层非均质性强,属于特低孔、特低渗油藏。对油藏特性进行深入研究,提出选取菱形反九点注采井网系统开发部署来提高油藏的开发价值。Wucangbao oilfield is located in the middle of Yixia slope in Ordos Basin, which is a front part of Wuqi Delta. In the drilling process, through stratigraphic correlation studies and core analysis, it is discovered that average porosity is 8.0% and average permeability is 0.23×10-3μm2 in Chang 9 reservoir in Wucangbao. The pore throat radius is small and reservoir heterogeneity belongs to particularly low porosity and low permeability reservoirs. With deep study of reservoir characteristics, the diamond-nine-injection well pattern is proposed to improve the value of reservoir development.
