渤南洼陷北带沙三下-沙四段砂砾岩储层成岩作用
|
摘要
成岩作用研究是油气勘探过程中重要的研究内容,因此,石油地质学家十分关注储层成岩作用。在碎屑岩埋藏过程中,成岩作用对砂岩孔隙的演化有着重要的作用,成岩作用最终决定了储层质量的好坏。本次研究通过大量的扫描电镜、铸体薄片、阴极发光、X-射线衍射、黏土矿物等分析化验资料,对渤南洼陷北部陡坡带砂砾岩储层成岩作用类型、主要影响因素进行了分析,同时划分了成岩演化阶段,并在此基础上分析了成岩相类型和不同成岩相对储层质量的控制作用。
Diagenesis is an important research content in the process of oil and gas exploration.Therefore,petroleum geologists pay close attention to reservoir diagenesis.During the burial process of clastic rocks,diagenesis plays an important role in the evolution of sandstone pore. Diagenesis ultimately determines the quality of reservoir.In this study,a large number of analytical and laboratory data,such as scanning electron microscopy,casting thin section,cathodoluminescence,X-ray diffraction,clay minerals,etc.,were collected.The diagenesis types and main influencing factors of glutenite reservoirs in the northern steep slope zone of Bonan depression are analyzed.At the same time,the diagenetic evolution stages are divided,and on this basis,the diagenetic facies types and the controlling effects of different diagenesis on reservoir quality are analyzed.
