| 摘 要： | 在研究影响天然气在地层水中溶解能力各种因素的基础上,分析了造成水溶相天然气释放的地质条件。通过物理模拟实验,不仅证明水溶气在运移过程中析出的游离气量的大小主要受温度、压力的控制,并获得了温度、压力变化时,单位体积饱和天然气的地层水析出游离气量的回归方程,为估算气藏中水溶释放气贡献量研究基础数据提供了计算方法。

| Abstract: | Based on analysis of various factors affecting solubility of natural gas in formation water,the necessary geological conditions for releasing water soluble gas was studied.By experiment of physical modeling,it was observed that the amount of free gas from water soluble part was mainly controlled by temperature and pressure during its migration and a regress equation for describing free gas changes was proposed.The equation provided a solution in estimating the contribution of water soluble gas to a natural gas reservors. |
