摘　　要：气井的无阻流量是产能评价中最为重要的指标。现有的气井产能测试方法对测试资料要求高,针对上下古气藏复合开采的M气田,低渗、致密气藏气井压力恢复慢,评价周期长以及气田新区开采测试资料少的情况,本文提供了一种低渗、致密气藏气井产能评价新方法,基于对历年试气测试资料的修正,探索不同气藏条件下气井产能与压力、产气量的耦合关系。该方法简单可靠且方便快捷,对气井产能准确快速评价、节约气田生产管理成本、指导新区气井合理生产制度具有重要意义。The open flow capacity of gas well is the most important index in deliverability evaluation.Existing gas well deliverability test method of test data demand is high.M compound mining field consists of upper and lower paleozoic gas reservoir.Low permeability results in slow pressure recovery and long evaluation period.All this makes the situation of the mining field district less test data.This paper provides a kind of new method of gas well deliverability estimation in low permeability and tight gas reservoir.Based on historical gas test data,explore the coupling relationship between gas well deliverability,pressure and gas production under different gas reservoir conditions.The method is simple,reliable,convenient and fast,which is of great significance for accurate and rapid evaluation of gas well deliverability,saving production management cost and guiding reasonable production system of gas wells in new area.
