试井工作制度制定方法探讨

针对大庆油田现场油气井测试常采用二开一关或二开二关工作制度存在的弊端 ,提出应根据地层情况推广使用一开一关工作制度 ,从而达到有效缩短测试周期 ,兼顾求产、测压和解释参数的目的。通过 30层探井测试资料的压力对比分析及不符的特殊井例进行原因分析 ,认为可以利用关井实测和试井解释参数外推的方法获得地层静压。

A Brief Discuss for Method of Making Well Test Working System

To the bad points of using working system of two open-one close or two open-two close in well testing operation of Daqing oilfield,the paper suggests a outline of work of one open-one close,which is based on formation situation,to reach the guides of shortening testing period,calculating production,recording pressure and interpreting parameters.By comparing interpreted pressure data of 30 developing wells and analyzing causes of none coincidence special wells,it is thought that using out derived method of parameters tested in close time and interpreted can get static pressure of formation.
