摘　　要：为确定气井合理工作制度,通常采用产量与生产压差关系指示曲线方法。在多个连续工作制度求产后,还需要一个放大的油嘴工作制度求产,测出气井产量与压差关系指示曲线上的拐点。这样,无形中损失了大量的天然气。通过对IPR流入曲线的分析,同样可以确定气井合理的工作制度,不需要最后放大油嘴的工作制度求产试气,可节省大量天然气资源。In order to define reasonable working rule in gas well,method of indicative curve about relationship between production and producing differential pressure is usually used.The corner in the indicative curve about relationship between production of gas well and producing differential pressure is acquired by using one enlarged choke to find production after finding production by many continuous work rules.So it loses a large quantity of natural gas.By analysis of IPR curve,a reasonable working rule in gas well can be determined too which needn't enlarge choke to find production,and save a large quantity of natural gas resources.
