| 摘 要： | 伊朗Kashan地区库姆组形成于混水碳酸盐岩台地沉积环境,以碳酸盐岩与陆源碎屑岩的混合沉积为主,沉积特征受陆源碎屑的影响较大.库姆组自身储集条件偏差,裂缝和溶孔在储集空间中占绝对优势,断裂活动及相伴生的溶蚀活动是控制储层发育的主要因素,而沉积相则为之提供物质基础.有利储集相带主要分布在应力集中区域和岩石破裂地区,其中局限台地滩相和三级层序界面之下的岩溶带是最佳储层发育位置.

| Abstract: | Qum Formation is formed in mixed siliciclastic and carbonate depositional environments, and terrestrial supplies influence on the characteristics greatly. And cores and rock slices show that the reservoir of Qum Formation is not very good and cracks and dissolved cavities are the main reservoir space. Fracture and dissolution interrelated with fracture are the primary factors controlling the reservoir whereas sedimentary facies provide the substance. The research has revealed that favorable reservoir rocks mainly exist in the centre of stress and fracture where shoals in constricted platform and dissolved strata just below 3rd sequence boundaries are the best . |
