我国产出剖面测井回顾

A Review of Production Profile Logging in China.

回顾了具有中国特色的产出剖面测井的发展历史 ;阐述了 2 0世纪 70年代后主要针对抽油机井而发展的几种测井新工艺 ;重点分析了我国产出剖面测井仪器主要应用的流量及含水率传感器 ;剖析了针对我国大多数油井产量低而发展起来的皮球和伞式集流器 ;讨论了多参数测井仪及小直径低流量测井仪 ;指出针对我国绝大多数油井为抽油机井的情况和单井产量较低的特点 ,应重点推广过环空测井技术 。

The developing history of production profile logging with China characteristics is reviewed in this paper.Several new logging technologies developed for pumping unit well in 1970’s are introduced briefly.It puts emphasis on analyzing flowrate & watercut transducers used in production profile logging tools in China. The rubber ball & basket flowmeters developed according to most of lower production wells in China and mutilparameter & lower flowrate tools with slim diameter are discussed herein.Meanwhile,it is pointed out that since the majority of oil wells in China are pumping wells and production rate of single wells is also lower, it is necessary to spread annulus logging tools and use packer type tools to improve their reliability and successful logging run rate.
