| 摘 要： | 本文指出了Magoon关于成熟烃源岩体个数划分含油气系统方法的局限性,以油气势能理论为依据,提出了一种以主要高势面划分含油气系统的新方法。剖面上,主要高势面多为区域性分布的烃源岩层、岩性致密层或成岩致密带;平面上,高势面即为油气分割槽,主要为盆地轴线或封闭性良好的大断裂带,将含油气系统进一步划分出多个亚含油气系统。 松辽盆地北部东区可划分为上、中、下三套含油气系统;平面上,下部含油气系统又可进一步划分出五个亚含油气系统。

| Abstract: | In this paper, the author pointed out the limitation of division method of petroleum system given by Magoon. Based on oil and gas potential theory, a new method which petroleum system is divided according to the main high potential interface has been advanced. Vertically, the main high potential interface is regional source rock, lithological dense layer or diagenetic dense zone; planarily it is separation trough mainly of basin axial line and large fractural belt with good sealing condition: they divide the peti- oleum system into many sub-systems. Thiee petroleum systems (upper, middle and lower) have been divided in the eastern region of the northern part of Songliao Basin and five petroleum sub-systems were further divided for the lower system. |
