| 摘 要： | 以地表地质调查成果为基础,以钻探、地质综合录井、核磁共振测井、电成像测井、正交多极子阵列声波等测井方法为手段,以岩石学特征、储层物性、储集空间类型和储集性能研究为重点,开展准南冲段带东段乌鲁木齐一带二叠系芦草沟组页岩油气评价。研究结果表明:该区带芦草沟组页岩含油气7层,其中优质含油层2层(64和66层);页岩储层矿物成分以高脆性矿物为主,物性特征表现为天然高导裂缝发育和低孔特低渗;油气藏表现为具中等含油饱和度的典型裂缝型油气藏特征。页岩储层各向异性较强,总体最大水平主应力为NWW向。

| Abstract: | Based on the results of surface geological survey, combined with the drilling , the geological compound log- ging, the Nuclear Magnetic Resonance logging(NMR), the Electrical Imaging logging (EI), the Orthogonal Multipole Ar- ray Acoustic Imaging logging (OMAAI), the Element Capture logging (EC) and other special logging techniques. the pa- per focuses on the study of petrological characteristics, reservoir physical properties, reservoir space types and reservoir properties.The results show that there are 7 hydrocarbon-bearing layers in Lucaogou Formation shale in Lucaogou For- mation in Urumqi Region of South Margin thrust belt of Junggar Basin, including 2 high-quality oil-bearing layers (64 and 66 layers). Which was characterized by the high brittle minerals , the high natural conductivity fractures, the low po- rosity and permeability and medium oil saturation. And the shale reservoir have been strong anisotropy and strong anisot- ropy of shale reservoir, which the direction of the maximum horizontal principal stress was NEE-SWW. |
