摘要 在沉积相研究的基础上,根据铸体薄片、扫描电镜及物性资料观测的孔隙及成岩特征进行分析,探讨直罗油田比6储层的孔隙特征及其影响因素,明确储层储集性能的主要控制因素。直罗油田长6储层的孔隙类型以长石、岩屑、碳酸盐胶结物溶蚀产生的次生孔隙为主,微喉为其主要的渗流通道。该区主要的成岩作用为压实及压溶作用、胶结作用、溶蚀作用。沉积环境对储层有着先天性的控制作用,压实及压溶作用、胶结作用使储层原生孔隙迅速减少,储层物性变差,溶蚀作用改善了砂岩的孔隙结构,但程度并不大,最终导致本区长6储层低孔低渗的特点。 Through researching the pore features and influencing factor of the reservoir, clearing the controlling factors of reservoir. Based on the sedimentary facies research, using the thin sections, scanning electron microscope observations and physical property, the pore and diagenesis features are analyzed. The main pore types are seconda- ry pores of feldspar, debris and carbonate cements in the Chang 6 of the Zhiluo Oilfield. The micro larynx is the main seepage passage. The diagenesis include compaction, pressure solution, cementation, and dissolution. Reser- voir is controlled by the sedimentary facies zone. The compaction, pressure solution and cementation lead few pore and reservoir's poor physical property, dissolution improves pore features to a certain extent, because it is not large- ly. Finally, it leads the characteristics of low porosity and low permeability in Chang 6 reservoir.
