沉积岩的有机质丰度低，基本无有效生油岩发育。

The organic matter abundance of sedimentary rock is low, and there is basically no effective source rock.

下古生界烃源岩在西部坡折带及南北隆起区现今仍处于有效生油窗内（镜质组反射率小于1.3 % ）。

Nowadays, at the western slope and the northern and southern uplifts the Lower Paleozoic source formations are still in the active oil generation Rold ( R o< 1.3%).

应用有机显微组分分析、生物标志物检测和藻类鉴定新技术，能有效分析盐湖相烃源岩的生油潜力。

To apply some new techniques such as the organic maceral analysis, biological marker inspection and alga authentication, can research hydrocarbon generation potential in salt-lake facies effectively.
