摘要(Abstract)：

根据汪家屯—升平地区深层气具有含气层位较多、储层类型多样的特点，分析了从基岩到泉四段不同层位、不同类型的储集岩天然气的聚集情况。同时，通过对盖层的微观封闭特点、宏观分布特征以及盖层封闭史与烃源岩排烃史的匹配关系的研究，分析了深层断层的封闭性及各类断层对天然气聚集所起的作用。研究表明，保存条件控制着本区深层气的分布。
In this paper, probability method for composite identification is put forward aiming at many uncertain factors in the identification of oil, gas and water layers in exploration wells. That is to calculate the probability value of different types of reservoirs under various parameter conditions by using Bayes Formula from probability theory. Different parameters are given different weight values according to experts' experience. In this way the probability model for identification of oil, gas and water layers in the exploration area is obtained. After programming, the method is applied in Puxi and Xinzhan Area in the western part of Songliao Basin, and good composite identification effect is obtained.
