摘　　要：针对辽河盆地不同构造天然气分布程度不同的现象，研究了控制其分布的地层流体超压体系的特点及其计算方法，提出辽河盆地存在多个超压体系，且受控于沉积、成岩和构造三种因素，指出地层流体超压体系对天然气具有很强的封盖能力。This paper studied the feature of formation fluid geopressured system that control the distribution of natural gas in various structure, and gave the calculation formula of pressure of geopressured system There are many geopressured systems in Liaohe basin, and they were controlled by sedimentation,diagenesis and structure. The formation fluid geopressured systems have strong closed capability to natural gas.
