摘要
建南气田飞三气藏有效渗透率低,气井产能测试一般采用单点测试,以一点法计算无阻流量。在对目前已有测试数据进行分析的基础上,对一点法公式中的α系数进行修正,得到了适应于建南气田飞三气藏产能预测的改进的"一点法"方程,误差比常规的"一点法"方程小,更能适合建南气田飞三气藏的产能预测。其修正产能系数为α=0.23。
In Jiannan Gas Field,gas well potential tests of Feisan gas reservoir are always conducted on single point and open flow capacity is calculated with one point method due to the low effective permeability.Based on the analysis of the existing test data,this paper suggests revisions to the α coefficient(revised to 0.23) in the one point method formula,thus getting a modified version of one point method with fewer errors which better suits the potential tests of Feisan gas reservoir in Jiannan Gas Field.
