滨里海盆地石油地质特征及勘探方向分析

滨里海盆地是里海地区最重要的含油气盆地之一，拥有十分丰富的油气资源。在对滨里海盆地的石油地质特征进行综合研究的基础上，着重对该盆地生烃及运移进行了分析，同时结合已发现油气藏的分布及圈闭类型认为，孔谷组盐岩层在滨里海盆地油气成藏过程中(特别是对盐上油藏)起着重要的控制作用。最后，给出了在该盆地盐上层和盐下层进一步勘探的方向。

Petroleum geology characteristics and exploration direction analysis of pre-Caspian Basin

The paper summarizes a comprehensive study of petroleum geology eharacteristics of Fre-Caspian Basin, with emphasis on the hydrocarbon generation and migration. Through analyzing the distribution of the discovered reservoirs and the characteristies of different types of traps, the authors consider that the Kungurian FM salt bed played a key role in the process of reservoir formation throughout the Basin, especially to the reservoirs above Kungurian FM. The authors also point out the direction of further exploration in strata above and below Kungurian FM.
