Comparison of hydrocarbon accumulation geological conditions between Sinian strata in Sichuan Basin and Tertiary strata in central Iranian Basin
摘要
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.关键词
