摘　　要：国内各大油田近年来相继引进了美国贝克休斯公司生产的Advantage综合录井仪,由于该仪器深度测量系统的绞车传感器采用的是电位器式模拟量传感器,在使用中存在一些问题而给录井作业带来不便。针对使用中存在的问题,结合其工作原理、软硬件设计,对绞车信号数模转换器进行了改进研制。经录井试验,供Advantage综合录井仪专用的这种绞车信号数模转换器不仅便于录井工作人员使用、降低了成本,还为研发其他用于深度、长度测量的产品提供了可供借鉴的经验。In recent years, each oilfield at home has imported the advantage comprehensive mud logging units from Baker Huges Inc. Company (U.S.A.) one after the other. Because the drawworks sensors of the depth-measuring system of it adopt potentiometer mode analog sensors, this results in some problems during using and brings some inconveniences to mud logging operation. In view of the problems existing in usage, combining with operational principles, software and hardware design, the improvement and development on the drawworks signal D/A converter was made. Through mud logging experiment, the results proved that the improved drawworks signal D/A converter, which was specially used for the advantage comprehensive mud logging unit, is not only convenient for mud logging personnel using, but also reduces the cost and also provides the reference experience for studying and developing the other products that are used to measure depth and length.
