| 摘 要： | 根据岩心观察、铸体薄片及压汞曲线等资料,对胡尖山油田长4+52储层的岩石学特征、孔喉特征及成岩作用等进行了深入的研究,并对储层进行了综合评价。研究结果表明,胡尖山油田长4+52储层岩性主要为极细—细粒长石砂岩和岩屑长石砂岩,储集空间主要为残余粒间孔和长石溶孔,片状和弯片状喉道为主要渗流通道,成岩作用类型主要包括压实作用、胶结作用和溶蚀作用。长4+52储层类型以Ⅱ类和Ⅲ类为主,为典型的低孔、超低渗储层。

| Abstract: | Based on core observation,cast thin section and intrusive mercury curve, the petrology characteristics,pore throat characteristics and diagenesis of Chang 4+52 reservoir in Hujianshan Oilfield are studied, and the reservoir is comprehensively evaluated. The result shows that the lithologies of Chang 4+52 reservoir are mainly fine arkose and lithic arkose, the reservoir spaces mainly are residual intergranular pore and feldspar dissolved pore, and the lamellar throat and curved lamellar throat are the main s... |
