华北地区古生界生油岩在三叠纪末已进入主要生油期。

The paleozoic source rock in North China went into the main oil generating period at the end of Triassic.

塔里木盆地石炭系为该区的主力生油层系。

Carboniferous system in the Talimu basin is main source sequence.

鸡西盆地生油气层较厚，分布面积广；

The hydrocarbon generated beds are thick and its distribution area is large;

结果表明：勃利盆地东部电性中低电阻率区不利于生油，而是一个寻找煤层气的有利地区；

The results show that the low-resistivity area in the eastern Boli basin is not a conducive area of oil, but a favorable area for coalbed methane;

黄河南地区的油气主要来自邻近的前梨园、葛岗集和崮阳3个洼陷的沙河街组三段和四段生油岩。

Hydrocarbon in South Yellow River Region are derived from Sha 3 ~ 4 member source rocks of the neighbouring front Liyuan, Gegangji and Guyang Sags.
