| 摘 要： | 本文据四川盆地西部致密碎屑岩储层特征,建立了储集体的概念。储集体是一个具备有效孔间和渗滤通道、不受岩性和层界严格限制的三度空间的地质块体,是致密碎屑岩气的重要储集形式。文中结合了川西拗陷的地质情况,划分了储集体类型,探讨了储集体的识别方法及形成条件。

| Abstract: | In this paper, a reservoir system is proposed based on the characteristics of the tight clastic rocks in the western Sichuan Basin. Such a reservoir system is defined as a geological body with effective pores and permeable channels of three-dimentional space,but without limitation on lithology and formational boundary. It is an important reservoir pattern for gas accumulation in tight clastic rocks. With combination of the geological settings of the west Sichuan Depression, the authors discuss the identification and the formative conditions of the reservoir systems in the paper. |
