注入井流量测井仪综述

如何根据注入井特点，研制开发出适合于我国中、后期油田吸水剖面测井需要的流量测井仪器一直是油田内外科技工作者不懈追求的目标。文章介绍了国内外测流量的几种仪器，包括：同位素示踪仪、涡轮流量计、电磁流量计、超声波流量计、脉冲中子氧活化仪等，对它们的结构、原理、优缺点和应用进行了较为详细的阐述、比较与分析，得出只有综合应用这几种仪器，才能提高注入井流量测井资料质量。

Overview of the injection well flow rate log instruments

According to the feature of the injection wells, how to develop flowmeters which are suitable for the water injection profile logging on the maturing oilfields has always been sought for by Chinese scientists and technicians. The paper introduces a few domestic and international flowmeters, including the isotope tracer tool,turbine flow-meter, electromagnetic flow-meter, ultrasonic flow-meter, pulse neutron oxygen activation logging tool, etc. The paper also analyzes and compares the construction, principle,advantages and weaknesses of them as well as their application. It is pointed that only by combined applying these instruments can we improve the quality of the water injection logging data. Suggestions about how to develop flowmeters in China are given which will improve the relevant research work of the same instruments in the future.
