核磁共振测试天然气藏可动气体饱和度

评价油气田开发潜力的一个重要的指标是可采储量。为此，对苏里格气田岩心借助可动油饱和度测试方法，对天然气藏可动气体饱和度测试方法进行了探讨，提出了利用甲烷和丙烷的混合物办法，解决了因天然气中氢含量低于油水等液体，测试的噪音很大，信噪比严重降低的问题。然后，针对气藏开发中的可动气体饱和度影响因素（含水、组分、地层压力）进行了系统的分析研究，为今后寻找有效的气藏开发方法和气藏勘探目标提供了依据。

NMR TESTING OF MOBILE GAS SATURATION OF GAS RESERVOIRS

Based on the testing method of mobile oil saturation, this paper discusses the testing methods of mobile gas saturation in gas reservoir by using the cores of Sulige gas field. It is proposed to solve the problems of strong noise and very low signal-to-noise ratio during testing by using the method of mixing methane and propane. The factors influencing mobile gas saturation during development of gas reservoirs, such as water content, composition and formation pressure, are systematically studied, so as to provide a solid basis for selecting an effective development method and for determination of exploration targets of gas reservoir.
