本文通过研究气井产能的可比性,得到一种计算气井绝对无阻流量及预测气井生产动态的简易方法。运用这个方法只需一个“单点”的回压试井资料,其有效性已被31个气田的31口气井的常规试井成果所验证。
In this paper, by studying the comparability of gas well productivity, a simple method of calculating the absolute unobstructed flow rate of gas well and predicting the gas well production dynamics is obtained. Using this method requires only a “single-point” back-pressure well test data, the effectiveness of which has been verified by the conventional well test results of 31 gas wells in 31 gas fields.
