| Abstract: | 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. |
