川东北地区复杂碳酸盐岩储层裂缝形成机理和控制因素
|
摘要
本文以川东北地区嘉二段为例,在野外露头实测、岩心和薄片统计的基础上对储层裂缝的发育类型和发育特征进行阐述,同时结合包裹体、声发射实验和川东北地区构造演化史,对构造裂缝的形成机理进行分析.该地区构造裂缝形成于3个时期:第一期为晚燕山期北西-南东向挤压作用,第二期为早喜山期北西-南东向挤压作用,第三期为晚喜山期的北东-南西向挤压作用.该地区构造裂缝的发育程度主要受到岩性、层厚、构造、沉积微相和成岩作用等因素控制.
In order to study the forming mechanism and controlling factor of complex carbonate reservoir fracture in northeastern Sichuan Basin.Taken the Jialingjiang formation as an example and based on the measurement in outcrop,rock core and thin section,the types and characteristics of fractures were analyzed and the fractures forming mechanism was also presented combined with the fluid inclusion experiment,acoustic emission experiment and tectonic evolution history.The structural fractures were formed during 3 periods:the first period was in the late stage of Yanshan tectonic movement under the NW-SE compression;the second period was in the early stage of Himalayan tectonic movement under the NW-SE compression;the third stage was in the late stage of Himalayan tectonic movement under the NE-SW compression.The structural fractures were controlled by the factors of lithology,layer thickness,structure,sedimentary microfacies and diagenesis action.
