大庆长垣东西两侧萨、葡、高油层天然气成藏条件的差异性

The Difference Between the Formation Conditions of Gas Reservoirs for S.P.G. Oil Layers in the East And West of Daqing Placanticline

通过大庆长东西两侧萨、葡、高油层天然气成藏条件的比较 ,指出二者在四个方面存在着差异 ,即大庆长垣以西地区青山口组和嫩一、二段源岩向萨、葡、高油层的供气条件优于大庆长垣以西地区 ;大庆长垣以西地区青山口组和嫩一、二段源岩向萨、葡、高油层的排烃条件明显优于大庆长垣以东地区 ;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大庆长垣以西地区 ;大庆长垣以西地区萨、葡。

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 pointed out that there are four differences in their formation conditions of gas reservoirs.The providing gas condition of K1qn and K1n1+2 to S.P.G oil layers in the West of Daqing placanticline is better than that in the east.The providing gas coudition of K 1sh+ych to S.P.G oil lcyers in the east of Daqing placanticline is better than that in the west.
