利用试井数据确定凝析气藏气水界面位置

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。当地层被完全钻开时 ,气水界面的位置除了可以通过测井解释和试气资料确定外 ,还可以通过试井所测的静压和压力梯度来确定。为动态掌握凝析气田气水界面位置提供一种方便、快捷的方法 ,指导凝析气田合理开发、控制采气速度具有深远的影响。应用该方法确定牙哈凝析气田油水界面位置与实际情况较为吻合

Determining Depth of Gas and Water Interface in Condensate Gas Reservoir Using Test Data

Site of gas and water interface in reservoir plays an important way to locate area bearing gas,determine depth of it and calculate reserves.When formation is drilled fully,the site of gas and water interface which is not only determined by logging or testing data,but also done by measured static pressure and pressure gradient.That provides a handy and quick way to know the position of interface dynamically and plays deepen influence in instructing development to condensate gas field and controlling the speed for recovering gas.Application of this method shows that the result of determining depth of gas and water interface in Yaha condensate gas field is matched to actual situation.
