| 摘 要： | 水溶释放气是气藏形成的重要组成部分，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，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。并以松辽盆地阿拉新气田为例计算水溶气释放量对气藏形成的贡献量。

| Abstract: | Water-soluble released gas is an important part for forming a natural gas reservoir.This paper analyzed the geologic conditions releasing water-soluble gas as necessary,based on the various factors affected solvability natural gas in formation water.By the experiment of physical modeling,a regression equation is obtained for free gas amount lib-erated from formation water at saturated natural gas per cubic meters when variations of temperature and pressure.In ad-dition,this paper,taking Araxin gas field in Songliao basin as an example,estimates the contribution of water-soluble gas to forming a natural gas reservoir. |
