四川盆地香溪群有水气藏天然气储量计算方法

四川盆地香溪群有水气藏气井普遍产水甚至水淹停喷，生产困难，采出程度较低，为了进一步挖掘各产水气井的开采潜力，采用更适合该区局限水体特征的物质平衡方法计算天然气储量，在计算过程中忽略了水侵量的大小。计算结果表明地下储量较大，部分产水气井和水淹井尚有较大开采潜力。

Reserves Estimate of Water-Bearing Gas Reservoir in Xiangxi Group, Sichuan Basin

Gas wells of the water-bearing gas reservoirs in Xiangxi Group of Sichuan basin are universally producing water and are even submerged in water,which results in production difficulties and low degree of exploitation.The paper used the material balance method,which is more conformable with the limited water volume characteristics in this area,to calculate the gas reserves in order to heighten the exploitation potential of every gas well of producing water.The volume of water flowed is omitted in size.The calculating result displays that the gas reserve is large,and that some gas wells producing water and submerged in water maybe have a large potential and that the gas segregated by water can be produced when the reservoir water is exploited.
