分层注水井验封工艺技术及量化解释新方法

Sealing Test Technology and New Quantized Interpretation Method for Separate Water Injection Wells.

针对分层注水井单压力计验封无法监测检验压差 ,成功率较低 ,同时对封隔器漏失程度也无法进行量化分析等问题 ,研究出了双压力计验封工艺技术及验封量化解释新方法。利用比值法可以较好地对封隔器的漏失程度进行量化分析 。

In view of impossibility for single gauge sealing test to monitor differential pressure,low success ratio and impossibility of quantized analysis to packer leak-off degree in separate water injection wells,the dual gauge sealing test technology and a new method of sealing test quantized interpretation were developed.Using rationg technique may better analyze quantized packer leak-off degree,while using unstable seepage flow technique may accurately calculate leakage of the string.
