【摘要】 中国叠合盆地深层碳酸盐岩储层和油气藏形成的特殊性是学术界和油气勘探部门十分关注的问题。四川盆地上震旦统灯影组是中国叠合盆地最老的碳酸盐岩储集层之一;中伊朗盆地第三系库姆组是世界上极具特色的含陆源碎屑火山碎屑的碳酸盐岩混积地层。四川盆地震旦系较古老,所经历构造演化、成岩过程复杂;而中伊朗盆地库姆组则时代较新,所经历构造演化、成岩过程相对简单。通过对四川盆地丁山1井灯影组碳酸盐岩和中伊朗盆地Arn 1井第三系库姆组碳酸盐岩的比较性研究,发现两者在碳酸盐岩储层和油气藏的形成演化方面,既有共性又有特殊性。就储层而言,共性表现在均为裂缝孔隙型,原生孔隙基本消失殆尽,基质孔隙度较低,非均质性较强;特殊性表现在使灯影组早期储层空间保留至今和使早已致密的碳酸盐岩再次变为优质储层的作用和机理。就油气成藏而言,碳酸盐岩油气藏的形成均需要基本的油气地质条件,同时也均较复杂;不同的是,四川盆地震旦系油气的成藏过程更加复杂,主要表现在四中心(生烃中心、生气中心、储气中心和保气中心)的变迁和耦合。在中国叠合盆地碳酸盐岩油气勘探中,应充分引用国外碳酸盐岩的有关成果,研究碳酸盐岩的共有特征;同时,还应重视中国叠合盆地碳酸盐岩储层发育和油气藏形成演化的特殊性。更多还原

【Abstract】 The particularities of deep carbonate reservoir rocks and hydrocarbon accumulation of superimposed basins in China are a issue which academia and oil and gas exploration organizations concern.The Upper Sinian Dengying Formation in Sichuan Basin is one of the oldest carbonate reservoir strata of superimposed basins in China.The Tertiary Qom Formation in central Iranian Basin is characteristic diamictic carbonate strata containing terrigenous and volcanic clastics.The Upper Sinian strata in Sichuan Basin are ancient with the experience of complicated tectonic evolution and diagenetic processes.The Qom Formation in central Iranian Basin is young with the experience of relatively simple tectonic evolution and diagenetic processes.Through the comparison between the Upper Sinian Dengying Formation of Well Dingshan 1 in Sichuan Basin and Tertiary Qom Formation of Well Arn 1 in central Iranian Basin,it is found that there are commonness and particularities in the carbonate reservoirs and the formation & evolution of oil-gas pools.For the reservoirs,the commonness is that both of them are fractured-porous carbonate reservoirs with lower matrix porosity and stronger heterogeneity.The particularities of Dengying Formation are the effects and mechanism making the early reservoir spaces preserved up to now and turning the already tight carbonate rocks into high-quality reservoirs.For the hydrocarbon accumulation,the commonness is that basic petroleum geological conditions are needed and processes are complicated for both Dengying Formation and Qom Formation.But the hydrocarbon accumulation process is more complicated for the Dengying Formation in Sichuan Basin showing in the migration and coupling relationship between four centers(hydrocarbon generation center,gas generation center,gas storage center,and gas preservation center).Therefore,the deep carbonate rocks and hydrocarbon pools of the superimposed basins in China are particular with the common characteristics of carbonate rocks and hydrocarbon pools in the world.More foreign research outcomes about carbonate reservoirs should be referenced to make out the commonness of the carbonate reservoirs in explorating the oil-gas of superimposed basins in China.At the meantime,more attention should be paid to their particularities.更多还原
