| 摘 要： | 射孔是影响气井产能的关键因素,选择合理的射孔参数极其重要。气井由于其渗流特性与油井不同,因此,射孔参数的选择也与油井不同。根据气井的渗流规律和气层被钻井泥浆污染的特性,分析了射孔参数对气井产能的影响,同时与油井进行了对比,并进行了实例计算。提出近井带孔深对产能的影响较油井强烈;超过污染带后孔径又成为第一影响参数,这一特点与油井完全不同。

| Abstract: | Perforation is a key effect for gas well production.It is extremely important to choose reasonable perforating parameters.The seepage character and the parameters of gas well are different with that of oil well.This paper ,based on the seepage law of gas well and the characteristic of mud contamination in gas formation,analysis the gas well production affected by perforating parameters,and make a calculating example. The paper put forwards that near wellbore the production is more strongly affected by the p... |
