摘要

摘要: 伊朗盆地第三系地层沉积了巨厚的碳酸盐岩,且分布广泛。卡山地区库姆组碳酸盐岩储层研究发现,其分布具有北薄南厚、西薄东厚的特点;重要储层以泥晶-亮晶生物灰岩或生物碎屑灰岩为主;储集空间类型表现为原生与次生孔隙都较发育,原生孔隙有生物体腔孔、残余粒间孔与晶间孔,次生孔隙有铸模孔、粒间溶孔以及晶间溶孔;孔隙度较高,渗透性良好;其储层成岩主要受胶结、溶蚀作用影响,构造裂缝明显;镜下已检测到油气运移痕迹,证明卡山地区第三系库姆组碳酸盐岩层是良好的天然储层。

Abstract: The Tertiary stratum of Iran basin has thickly and broadly deposited great carbonate sediments.A study of carbonate reservoir of the Qum troop in Kashan area indicates that,reservoir distribution has a characteristic of thicker sediments in the south and east.The important reservoir mainly consists of micrite-sparite biological clastic limestone.In addition,primary and secondary pores are both developed in re-servoir space.Primary pore includes biological antrum pore,residual intergranular pore and intercrystalline pore,and secondary pore includes mould pore,intergranular solution pore and intercrystalline solution pore.Porosity is high with predominant penetrability.Lithogenesis is dominantly controlled by cementation and dissolution,and at the same time,tectonic fractures are apparent.Under microscope,oil and gas migration can be checked out easily,which proves that,the Qum troop carbonate rock of Tertiary in Ka-shan area is predominant natural reservoir.
