四川盆地海相碳酸盐岩的油气成藏条件
|
摘要
四川盆地位于亚洲大陆中南部,是我国最大的外流盆地。油气资源评价结果(2008)表明,四川盆地海相地层待发现资源量约为50111.84×108m~3,资源勘探潜力巨大。本文从地层的划分、层序格架及层序岩相古地理特征等方面,对四川盆地海相碳酸盐岩油气成藏条件做了进一步研究。认为研究区烃源岩包括下志留统、中二叠统、上二叠统龙潭组和上三叠统须家河组等4套岩石,及局部发育的上二叠统大隆组。储集层粉为构造成因类和沉积成因类,构造成因主要包括裂缝性储层;沉积成因类储层主要是礁滩储层、内幕白云岩储层和风化壳岩溶储层。中二叠统气藏主要为自生自储的裂缝性气藏和台内滩相气藏;茅口组顶部和雷口坡组顶部发育风化壳型气藏;吴家坪组、长兴组及飞仙关组地层含礁滩型气藏;嘉陵江组和雷口坡组地层含内幕白云岩型气藏。
The Sichuan basin is one of the most important oil and gas basins of marine carbonate sequences in China,also the earliest carbonate exploration,exploitation and utilization were conduced.The evaluation of its hydrocarbon resources(2008) suggested there is a considerable amount of undiscovered resources(approximately 50111.84 × 108 m~3) in the marine strata of this basin,implying a great potential of prospecting.This paper presents a further study on hydrocarbon accumulation conditions in this area based on strata classification,sequence patterns and characteristics of rock facies and paleogeography.The results suggest that the source rocks include four sets of Lower Silurian,Middle Penman,Upper Permian,and Upper Triassic systems.Reservoirs are of structural and sedimentary genesis,of which the former refers to fissures and the latter is is reef-beaches,dolomitite,and weathering crusts.These reservoirs are present in varied formations.
