辽河盆地气藏泥岩盖层条件初探

A Primary Discussion on the Conditions of the Mud Stone Caprocks of the Gas Reservoirs in Liaohe Basin

辽河盆地气藏的泥岩盖层有4种类型。盖层的优劣及其类型,明显地受沉积和构造双重作用的控制。在不同性质的凹陷中,盖层类型的组合及其分布均有所不同。

The mud stone caprocks of the gas reservoirs in Liaohe Basin are of four types. The good or bad and types of the caprocks are obviously controlled by both sedimentary and structural effects. The type combinations of the capocks and their distribution are different in distinct depression.
