摘要

双坨子气藏气井长期生产以来,井底的压力下降情况不清楚。鉴于目前的供气紧张状况和工艺技术的限制,无法测量出地下气层的压力。本项目组在参考了相关文献的基础上,使用了VisualBasic 语言成功地编制了一套软件。采用了平均法和Cullender & Smith 方法,既可以计算静止气柱的井底压力,也可以计算流动气柱的井底压力,成功地解决了求取井底压力的问题,有利于对比双坨子气藏的合理产能及动态储量做出正确地评价。

Abstract

Shuangtuozi gas pool is an integral gas-bearing structure that

being dcveloped in Jilin Oilfield currently.With the production for

so many years ,the pressrue of the gas-producing zones decline ,

but the exact figures are unknown. There are some difficulties in

shut in pressure surveying because of the urgent gas transmission

in winter and lack of technology. Our research group designed a

set of programs to sovle this problem sucessfully based on many

references. This paper mainly explains how the program proceeds

and which method is used in our designing.
