| 摘 要： | 本文从岩心和测井资料出发,研究酒泉盆地青西油田裂缝的类型和微观特征,通过区域构造背景和断裂特征分析,研究裂缝分布规律及与构造的关系,进而应用地震属性分析,结合钻井和测井资料对裂缝进行预测,得出以下认识:①下白垩统下沟组块状砂砾岩和泥质白云岩为典型的特低孔、低渗储层,裂缝为最主要的油气储集空间和运移通道,各种类型构造裂缝均有发育,但高角度裂缝和斜交缝对油气富集最为有效;②断层控制了裂缝的发育方向,裂缝发育带展布方向和断裂发育带展布方向基本一致,主要为北北东向和北西西向;③构造转折部位和断层交会带为构造应力集中的部位,裂缝发育;④裂缝的发育程度控制了油气的富集程度,北北东向调节断层产生的裂缝带是油气富集带。结合裂缝预测结果,在青西油田部署的L104井获得64m3/d的高产工业油流。

| Abstract: | From the core and logging data,in this article fracture types and microscopic features are analyzed in Qingxi Oilfield,Jiuquan Basin.Fracture distributions and their relation with geological structure are discussed based on regional tectonic background by seismic attributes,drilling and log data.The following observations are obtained.1.Massive sandstone and argillaceous dolomite in the Xiagou of lower Cretaceous are typical low porosity and low permeability reservoirs.Fractures are major hydrocarbon pore v... |
