HDCⅡ环空测井组合仪是继分测式环空测井组合仪之后开发的新型仪器 ,该组合仪引入了多路遥测短节 (WTC) ,测量参数增加到 7个 ,其中持水率和流量用集流方式测量。单片机控制技术的应用大大简化了电子线路 ,改善了仪器的性能 ,一次下井可同时录取 7个参数的资料。它的推广应用 ,可为抽油机井的动态监测提供更准确、齐全的资料 ,同时还可缩短施工时间。文章阐述了仪器结构特点、工作原理以及实际应用情况。
The HDCⅡ annulus logging instrument is a new instrument developed after the split annulus logging tool. The instrument introduced a multi-channel telemetry short section (WTC), the measurement parameters increased to seven, of which the water holdup and Flow measurement with current collection. SCM control technology greatly simplifies the application of electronic circuits, improve the performance of the instrument, a time can go down at the same time the admission of seven parameters of the information. Its popularization and application can provide more accurate and complete information for the dynamic monitoring of pumping wells and at the same time shorten the construction time. The article expounds the structural characteristics of the instrument, working principle and practical application.
