【 摘 要 】

There are three essential geological factors which interact and restrict each other's: sedimentation, diagenesis and tectonism, that control the development and evolution of carbonate reservoirs. Regard to karst carbonate reservoir, karstification plays a key role in the formation of carbonate reservoirs by the formation of dissolution pore system; The tectonic movement exposes or upthrow the strata and provides the conditions for karstification. The fractures generated by them can overwhelmingly improve the seepage capacity of carbonate rocks and promote the occurrence of karstification. This paper mainly discuss how sedimentary factors control the development and evolution of carbonate reservoirs in cretaceous Mishrif and tertiary Asmari formations in east southern Iraq.
