介绍了辽河盆地东部凹陷浅层气的分布和成因类型。阐述了该凹陷浅层气的成藏条件——气源条件、储层条件、盖层条件和构造条件。研究了该凹陷浅层气的富集规律,认为:烃源岩对浅层气分布富集规律有明显制约作用,储层分布规律是控制浅层气富集程度的重要因素,高质量的盖层是浅层气成藏的先决条件,构造及构造部位断层的发育程度也控制浅层气富集程度。
The distribution and genetic type of shallow gas in eastern depression of Liaohe Basin are introduced. The forming conditions of shallow gas in the depression are described - gas source conditions, reservoir conditions, caprock conditions and tectonic conditions. The enrichment of shallow gas in the depression is studied. It is concluded that the source rocks have a significant restraining effect on the distribution of shallow gas and the distribution of reservoirs is an important factor in controlling the enrichment of shallow gas. High-quality cap The layer is a prerequisite for shallow gas accumulation. The degree of development of faults in the tectonic and structural parts also controls the degree of shallow gas enrichment.
