【摘要】 分析比较了大庆长垣东、西两侧萨、葡、高油层油气成藏条件 .结果表明 :大庆长垣以西地区萨、葡、高油层较大庆长垣以东地区萨、葡、高油层发育 ;大庆长垣以西地区青山口组和嫩一二段源岩向萨、葡、高油层的供烃、排烃条件均优于以东地区 ;大庆长垣以东地区沙河子组 -营城组源岩向萨、葡、高油层的供气条件优于以西地区 ;大庆长垣以西地区萨、葡、高油层的油溶气释放条件明显优于以东地区 ;大庆长垣以西地区萨、葡、高油层圈闭条件优于以东地区 .这些成藏条件的差异导致了大庆长垣东、西两侧气田数量及储量的差别更多还原

【Abstract】 By comparing between the formation conditions of gas reservoirs for S,P,G oil layers in the east and west of Daqing placanticline, this paper points out the six differences in their oil or gas accumulation conditions. The development degree of S,P,G oil layers in the west of Daqing placanticline is better than in the east of Daqing placanticline. The gas providing condition of Klqn and Kln1+2 to S,P,G oil layers in the west of Daqing placanticline is better than that in the east of Daqing placanticline. The expulsion hydrocarbon condition from Klgn and Kln1+2 to S,P,G oil layers in the west of Daqing placanticline is better than that in the east of Daqing placanticline. The gas providing condition of Klsh+ych to S,P,G oil layers in the east of Daqing placanticline is better than that in the west of Daqing placanticline. The released condition of gas from oil for S,P,G oil layers in the west of Daqing placanticline is better than that in the east of Daqing placanticline. The trap conditions of S,P,G oil layers in the west of Daqing placanticline is better than that in the east of Daqing placanticline.更多还原
