确定气井的产能,必须要求在产能测试中获得准确的压力数据,而在实际应用中我们会发现并不是在生产的各个阶段都有压力测试的数据,或者测试的数据不准确。这使得常规产能方程无法分析气井产能,或者分析结果出现异常。本文采用了结合物质平衡的产能计算新方法分析气井产能。本方法用生产数据来计算地层压力和流压,并优化目标函数,最终获得可靠的压力数据及产能系数,从而得到生产各阶段的产能二项式方程,并可以进一步预测下一阶段的产能。本方法在实际应用中已获得了良好的效果。

Determine the gas well deliverability,it must require the deliverability pressure test to get accurate data,and in practical applications in which we find that there is not the pressure test data in the production of various stages,or test data is inaccurate.This has made regular deliverability equation cannot be used for the analysis of gas well deliverability or the analysis result was exception.This papered adopted with the New Combined with Material Balance of Deliverability Calculation Method to analysis the gas well deliverability.The new method uses production data to calculate reservoir pressure and flow pressure,further optimizes the objective function,finally it can get accurate pressure data and deliverability coefficient.Thus we can obtain turbulent flow equation in each production stage and be further we can forecast the deliverability of next stage.The new method obtained good effect in practical application.
