摘 要:依据任丘潜山碳酸盐岩储层研究成果及潜山油藏有关储层资料,分析了海相碳酸盐岩储层发育的影响因素。储层中泥质白云岩与粗结构藻白云岩韵律性的岩性剖面,纵向上储层与非储层交替出现,孔洞的发育顺层分布,形成同层渗透带;多次沉积间断,构成多岩溶期,并有沿风化壳的溶蚀缝洞带及古水平岩溶带;构造应力产生断层和构造缝发育带,可形成断裂高渗带;成岩后生作用及储层演化,经历了各种次生改造,形成现今的储层面貌。认为层位古老的碳酸盐岩储层,原生孔隙难以保存,储渗空间以次生为主。According to the research result of carbonate rock reservoir of Renqiu buried hill and relevant data about the reservoir of buried hill oil-pool,the paper has analyzed the factors that influence the marine carbonate rock reservoir development.In cycled lithologic sections of argillaceous dolomite and coarse texture algae dolomite,reservoir and non-reservoir alternately appear,which make pores and caves growing along the layer. Multidepositional break resulted in multi-karst and solution fracture and cave zones and paleo-horizontal karst belt developed along the crust of weathering.Faults and structural fractures caused by structural stress produce faulted-fractured high permeable zones.The present reservoir has undergone epigenesis,evolution and reformation.It is believed that the secondary porosity in old carbonate rock reservoir dominates over the pore space.It is difficult for the primary porosity to be preserved.
