特殊测井在准南地区乌鲁木齐一带芦草沟组页岩油气层评价中运用
|
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。
Based on the results of surface geological survey, combined with the drilling, the geological compound logging, the Nuclear Magnetic Resonance logging(NMR), the Electrical Imaging logging(EI), the Orthogonal Multipole Array Acoustic Imaging logging(OMAAI), the Element Capture logging(EC) and other special logging techniques. the paper 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 Formation 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 porosity and permeability and medium oil saturation. And the shale reservoir have been strong anisotropy and strong anisotropy of shale reservoir, which the direction of the maximum horizontal principal stress was NEE-SWW.
