| 摘 要： | 莫里青断陷烃源岩成熟度不高,在断陷的大部分地区只发现油藏,其溶解气含量也很低,但在断陷的东南部靠近东南缘的伊23井和伊14井发现了以气为主的气藏。认为莫里青断陷的天然气并非典型的油型气,也不是典型的煤型气,而是与其特定的母质类型有关的天然气;莫里青地区的天然气主要与凹陷深部的烃源岩亲缘关系密切;向东南方向,天然气发生明显的运移分异作用,伊23井和伊14井气藏是油气运移分异作用下形成的。

| Abstract: | The oil pools were mainly discovered in the part of Moliqing rift, a fewer gas pool was discovered. According to the new geochemical data and predecessor′ researches, the geochemical characteristic of natural gas and efficiency of migration in Moliqing rift were studied in this paper, in order to expound the origin of natural gas and distance of migration. The natural gas in Moliqing rift are mainly accompanying gas with crude oil, the content of heavy hydrocarbon is high. The natural gas in region of Moliq... |
