埕东油田埕913断块沙三段砂砾岩油藏储层特征研究

Characteristics of glutenite reservoir in Sha 3 formation of block cheng 913 in chengdong oilfleld

以井点分析为基础,利用核磁共振测井等资料,对埕东油田埕913断决沙三段储层岩石进行分类;应用岩石铸体薄片、扫描电镜、压汞、CT等资料,以砂砾岩储层孔隙结构特征为重点,对其储层特征进行了研究。通过CT分析,确定了储层孔隙度,为落实储量规模提供了依据。

Types of reservoir rocks in Sha 3 formation of fault block Cheng 913 in Chengdong oilfield are classified on basis of well point analysis by using data of nuclear magnetic resonance; reservoir characteristics are studied with focus on pore structure of glutenite reservoir by using data of thin section of rock, scanning electron microscope, mercury injection, and CT, etc. Reservoir porosity is determined through CT analysis, thus providing basis for reserve confirmation.
