摘要

摘要: 该文跟踪国外含油气盆地深部勘探研究的最新进展,在总结深部砂体发育异常孔隙的机理及控制因素基础上,以四川盆地川西坳陷中深部沙溪庙组(J₂s)储层为例,探讨了原生粒间孔隙的保存机制,指出绿泥石包膜、早期油气充注及异常高压发育是川西地区J₂s粒间孔隙发育的主要机制。

Abstract: Following up the late progresses on deeply buried sandstone in overseas petroliferous basins, and based on the origin and controlled factors of anomalously high porosity in deep burial reservoirs, the authors discussed, taking the Chuanxi sag in Sichuan basin for the best scenario, that the preserving mechanisms of intergranular porosity in mid to deep burial sandstone intervals, and indicated that the primary conservation mechanisms of intergranular porosity in Shaximiao formation are as follows: development of chlorite coating, early petroleum emplacement and shallow development of fluid overpressure.
- anomalously high porosity /
- chlorite /
- hydrocarbon emplacement /
- undercompaction /
- Shaximiao formation /
- western Sichuan Depression
