摘要
通南巴构造带飞三段鲕粒滩储层发育,属低孔低渗致密灰岩储层。利用测井、岩芯以及薄片等资料,从构造作用、沉积作用以及成岩作用等多方面探讨了该区飞三段鲕滩储层的主控因素。研究结果表明:飞仙关组三段鲕滩储层主要受沉积相、微古地貌、构造活动、成岩作用及多因素匹配等制约。台内滩滩核微相是鲕粒滩储层发育的先决条件;微古地貌高地为优质的鲕粒滩储层的形成和发育提供了必要的物质基础;颗粒滩暴露遭受大气淡水淋滤改造作用的强弱与改造时间长短是优质鲕滩储层形成的关键;构造破裂作用为储层孔、洞的沟通提供了桥梁,改善了储集体渗流能力;多因素匹配好则可形成优质储层。
The third Feixianguan formation oolitic reservoir in the Tongnanba tectonic zone is low-porosity, low-permeability and compact limestone. We make use of logging, core and slice to discuss the main controlling factors from respects of tec- tonic, sedimentology and diagenism. The results show that the oolitic reservoir is controlled by the sedimentary face, mi- cro-palaeogeomorphology, tectonic movement and diagenism. The preconditions of the oolitic reservoir growth is the core of intra-platform shoals, and the high spot of the ancient micro-landform provides the indispensable material basis; the key is the extent and the length of the exposure to air and transformation by fresh water leaching. The tectonic disruption makes possible the connection between the pore and the hole of the reservoir, and improves the infiltration fluid ability of the unit. The well match of the multi-factors may form the good reservoir.
