| 摘 要： | 姬塬油田胡150—胡153区长4+5油层组储层主要为湖泊三角洲前缘水下分流河道沉积,以长石砂岩和岩屑长石砂岩为主,属典型的低孔特低渗砂岩储层.运用铸体薄片、扫描电镜、铸体图像分析、阴极发光、高压压汞等测试技术手段,对该区长4+5储层进行分析研究,结果表明:该区储层性质明显受原始陆源组分、沉积相和成岩作用的影响.陆源碎屑组分是后期成岩作用改造的物质基础,储层性质受沉积相或微相的控制,水下分流河道砂体的储集物性明显优于其他微相砂体,成岩作用对储层物性优劣起主导作用,压实作用、胶结作用导致储层致密,物性变差,溶蚀作用尤其是长石的溶蚀作用对本区储层的改善具有重要意义.

| Abstract: | The Chang 4+5 reservoir in Hu150-hu153 area of Jiyuan Oilfield is mainly composed of the subaqueous distributary channel sandbody of lacustrine delta front,whose main lithology is arkose and debris-arkosic sandstone.The Chang 4+5 reservoir belongs to typical low porosity and extra-low permeability reservoir.Cast thin section,scanning electorn microscope,cast image analysis,cathodoluminescence,high-pressure mercury injection,and physical property data,etc.show that the characteristics of the reservoir is inf... |
