| 摘 要： | 通过对松辽盆地北部5套泥岩盖层和3套气源岩空间分布面积的比较,以及对盖层封闭能力形成时期与气源岩大量排烃期的比较,研究了松辽盆地北部5套泥岩盖层与3套气源岩之间的时间和空间匹配关系及其对天然气聚集程度的控制作用,指出扶杨油层和萨、葡、高油层是松辽盆地北部天然气聚集与分布的有利层位。扶杨油层天然气富集程度在空间上存在差异,大庆长垣以东地区好于大庆长垣以西地区。萨、葡、高油层和黑帝庙油层的天然气富集程度在空间上存在差异,大庆长垣以西地区好于大庆长垣以东地区。

THE MATCHING RELATION BETWEEN CAP ROCK AND SOURCE ROCK AND ITS CONTROL OVER THE GAS ACCUMULATION AND DISTIRBUTION IN THE NORTH OF THE SONGLIAO BASIN |
| |
| Abstract: | Through comparing the space distribution of five cap rocks and three source rocks in the north of the Songliao Basin,and the period that the sealing ability of cap rock was formed and the period that a great deal of oil or gas was expelled from source rocks,this paper studied the matching relation between cap rock and source rock in space and its control over gas accumulation and distribution,and the matching relation between cap rock and source rock in time and its control over gas accumulation degree.It is pointed out that Fuyang and Sa,Pu,Gao oil layers are favorable accumulation and distribution horizons for gasGas accumulation and distribution of Fuyang oil layer in the east of Daqing placanticline is more favorable than that in the west of Daqing placanticline.Gas accumulation and the distribution of Sa,Pu,Gao and Heidimiao oil layers in the west of Daqing placanticline is more favorable than that in the east of Daqing placanticline. |
