摘要
处理塔里木盆地和田河气田产能试井资料时,发现部分气井的回压试井资料存在一些问题,尤其是产量序列变化频繁,导致分析结果存在一定误差;以二项式产能公式为基础,从理论上分析了产量序列对回压试井测试结果的影响,给出4个生产制度的误差公式,结合现场实例认识到采用产量递增序列误差较小,且尽可能提高产量间等比系数,扩大每个制度间的产量差距,有利于减小误差,为回压试井设计提供一定依据。
There are some problems about back pressure testing data when the deliverability test data is processed in Hetianhe gas field of Tarim basin,test production sequence changes leads to a certain errors to be in results of the analysis. The influence of production sequence to back pressure well test is analyzed on the basis of binomial deliverability formula,four error formulae for production system are given. Combined with field examples,it is recognized that increasing sequence has the smaller error. And increasing geometric factor between productions as far as possible,widening the gap between productions that will help to reduce errors,which provides a basis for the back pressure well test design.
