利用系统试井数据库资料确定气井产能方法研究

地层测试技术是石油勘探开发中一项试油新技术,在新区勘探工作中,它是油气层早期评价的一种非常有效的手段,可及时发现油气层,认识地层特性与获得地层参数,但一般不作产能评价,对于气井来说不计算绝对无阻流量。确定气井产能有回压试井、等时试井与修正等时试井,计算绝对无阻流量的方法有二项式压力法,二项式压力平方法,指数式压力法,指数式压力平方法,一点压力法,一点压力平方法等方法。我们研究了利用不稳定试井数据库资料确定气井产能的方法。

THE WAY FOR DETERMINING GAS PRODUCTION WITH SYSTEM WELL TEST DATA

the technique of well test is one of new techniques for well test,which is utilized in new Exploration Area,and it is one kind of effective way to discover oil gas formation,get property and data of gas oil formation.but production evaluation could not be accomplished and Potential production of gas could not be obtained with the technique.the way to determine production of gas wall includes the technique of pressure build-up well test,equal time well test,amended equal time well test;the way to get Potenti...
