摘要
引发井筒效应的因素很多 ,在分析每种特殊井筒效应的起因时必须结合地层物性、相态变化、压井液比重和地层产出物等资料进行全面、细致地分析。本文具体分析了高比重压井液+复合测试管柱、油水两相 +多层、凝析气凝析引起的 3种特殊类型的井筒效应。通过分析 ,搞清了流动曲线和恢复曲线出现异常的原因 。
There are many factors generating wellbore effect, the information of formation physical property, phase change, killing fluid specific gravity and formation producing fluid must be combined to do an overall and careful analysis. This paper specifically analyzes be special types of wellbore effect such as high specific gravity killing fluid + composite test string, oil-water two phase + multilayer, effect caused by condensation of condensate gas. Through analysis, the cause of abnormality on flowing curve and build-up curve is clarified ,which clears away obstacles for test data interpretation. Subject heading
