气体饱和度

核磁共振测试天然气藏可动气体饱和度

NMR testing of mobile gas saturation of gas reservoirs

残余气体饱和度与地层性质相关。

The residual gas saturation is related to the properties of the formations .

临界气体饱和度是溶解气驱过程的重要参数，在不同的领域内它的定义不同，因此，不加说明易产生混淆。

Solution gas drive is an important displacement process . Critical gas saturation is an operating parameter which has different definition in different fields .

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。

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 .

分子取向程度越高，分子链间空穴的大小差距越小，气泡成核需要的气体过饱和度越大，开始形成气泡核的时间越晚。

As the orientation degree increases , size difference of voids becomes smaller , so the gas supersaturates degree needing for bubble nucleation increases .

气体过饱和度增大加速气体的释放和气泡的生长，进而导致岩浆的浮力增大，岩浆上升速度加快；

The volatiles super saturation increases with decrease of pressure , which accelerates degassing and bubble growing and results in magma density decreasing , buoyancy increasing , and magma accelerating ascend .

产生烃类气体的不饱和度随裂解能量密度（温度）的增大而增加。

Non-saturation of the hydrocarbon gas will be increased according to the increase of the density ( or temperature ) of the splitting energy .
