本文首次提出了利用测井资料确定气水界面的方法。
This paper proposes a method for determining gas-water contact with well logs.
地层中气水界面位置 ，对圈定气藏的含气面积 ，确定气藏厚度 ，计算储量极为重要。
Site of gas and water interface in reservoir plays an important way to locate area bearing gas, determine depth of it and calculate reserves.
随着石油的进一步聚积及油气的转化，使砂岩中的自由水逐渐被驱除，因此这种异常压力气田是不存在气水界面的。
The saturation of these compartments with liquid hydrocarbons and the subsequent oil-to-gas reaction causes the expulsion of free water, resulting in a gas accumulation without gas-water interface.
可以进行多次压力测试以建立地层压力梯度，从而判断油、气、水界面。
Multiple tests can be performed to measure formation pressure, and the formation pressure gradient can be established, accordingly, interface between oil, gas and water can be identified.
非饱和带裂隙中的饱和区和排干区可以用一个离散的气-水界面分隔开。
A discrete air-water interface is used to separate the saturated zones from the drained zones within each single fracture of fracture network.
根据气体溶解定律(亨利定律)：任何气体在水中的溶解度与该气体在气、水界面上的分压力成正比。
According to the law (Henrry Lay) of gas dissolve: the solubility of any gas in water shall be direct ratio with partial pressure of the gas on interface of gas and water.
只要将水定压加热到饱和温度时，气、水界面上蒸汽的分压力就会接近于水面上的全压力。
Only when the water that is limited pressure is heated to the saturate temperature, the partial pressure of steam that is on interface of gas and water shall close to full pressure on water surface.
