利用放射性示踪同位素和流量测井资料综合评价水井分层注水效果

Applying materials of tracer and flowrate logging to estimate the effect of zonal injection.

评价水井的分层注水效果是油田注水开发动态分析中必不可少的。文章介绍了电磁流量计与涡轮流量计测井方法,结合放射性示踪同位素测井资料,可综合确定分层注水量及封隔器座封质量和漏失情况,达到评价水井分层注水效果的目的。

This paper introduces logging methods of turbine flowmeter and electromagnetic flowmeter,as well as the tracer flow survey.Not only the flowrate from tube space to annular space is attainde,but also that from annular space to formation can be known.These help to estimate the effect of injection,including the quantity of zonal injection and the leakage of injection water well.
