摘　　要：确定气井产能的测试方法中,一点法产能测试方法较多点回压试井、等时试井、修正等时试井简单快捷,受到油田现场的广泛应用,特别适用于海上测试。但是传统的一点法产能经验公式求解具体气藏产能存在一定的局限性,计算结果与二项式结果偏差较大。同时,在计算气井产能时,为了简化计算过程,应用中通常将拟压力简化为压力平方求解,然而,这样笼统的将拟压力简化压力平方计算气井产能,对于异常高压气藏是不合理的。以一个异常高压气田(锦州M气田)为例,从理论分析入手,首先研究了拟压力在不同压力区间的不同简化形式对计算气井无阻流量的影响;然后基于锦州M气田丰富的测试资料建立了适合该气田生产特征的一点法产能计算经验公式。实例验证表明,该研究思路是可行的,研究成果是可靠的,可指导相关气田的产能研究。All test methods of determine the productivity of gas well,apoint deliverability testing method is more simple and quickly than others,and this method has been widely used in oilfield,especially suitable for offshore gas well test.But the traditional method of production experience formula to solve the specific gas reservoir has certain limitation,the calculation results is deviated with binomial result.At the same time,in order to simplify the gas well productivity calculation process,generally pseudo pressure will be simplified for pressure square.However,the simplify gas well productivity calculation process for abnormal high pressure gas reservoirs is not reasonable.Taking an abnormal pressure gas field(Jinzhou M gas field)as an example,starting from theoretical analysis,the first study of pseudo pressure in different pressure regions of different simplified forms on computing open-flow capacity of gas well;then based on Jinzhou gas field M abundant test data is established for the gas producing characteristics of a point deliverability calculation empirical formula.The example shows that,this research approach is feasible,and research results are reliable,which can be guidance to the relevant gas field production capacity study.
