应用同位素吸水剖面+流量四参数资料求取未测试层定量参数的解释方法

Interpretation method of applying radioisotope water injection profile and flow four-parameter log document to obtain quantitative parameter of unknown-formation

近年来大多数油田为了增强注水效果,提高采油效率,在注水井中分层配注井占到了较大比列,评价水井的分层注水效果,是油田注水开发动态分析中一种必不可少的资料。但分层配注井由于管柱复杂,往往存在底部部分射孔层遇阻,测试不到资料,致使遇阻射孔层无法获得反应吸水状况定性、定量参数的问题。文章通过对同位素吸水剖面+流量四参数资料的应用,研究。分析总结出了一种应用同位素吸水剖面+流量四参数资料求取未测试层定量参数的解释方法。

Recently the most field increased proportion of delaminating injection well for improving oil productivity,so it is indispensable method to the evaluation of delaminating injection well.But we don't obtain the destination document of delaminating injection well easily because complex hole.So we don't know the true quantitative parameter of destination.This paper has a interpretation method to obtain quantitative parameter of unknown-formation through studying radioisotope water injection profile and flow four-parameter log document.
