摘要:

通过对克百断裂下盘二叠系碎屑岩储层的研究,发现储集岩主要是细砾岩和砂砾岩;同时,研究区储集岩的物性以夏子街组为好,风城组和下乌尔禾组较差;在此基础上,结合岩心资料,通过薄片分析及扫描电镜分析,研究了成岩作用对研究区砂砾岩储层物性的控制作用:压实作用是储层物性最主要的破坏性成岩作用;受胶结物含量不同的控制,胶结作用对储层物性具有双重作用;溶蚀作用是研究区产生次生孔隙和裂缝,并具有连通作用的最重要的建设性成岩作用。

关键词: 克百断裂, 二叠系, 储层, 物性, 成岩作用, 控制作用

Abstract:

In the Permian detrital reservoir in the underlying block of Kebai fault, the main reservoir rock is composed of fine conglomerate and sandy conglomerate, with good physical property in Xiazijie Formation and poor property in Fengcheng and lower Wuerhe Formations. Based on core observation, rock slice and scanning electron microscope (SEM), we discussed the diagenesis constrain to the physical property of sandy conglomerate reservoir as follows:Compaction is negative to physical property of reservoirs; cementation performs the double actions depending on different quantity of cement matters; dissolution is positive to make secondary porosity and fracture as well as connectivity with pores.

Key words: Kebai fault, Permian, Reservoir, Physical property, Diagenesis, Constrain.
