本文介绍用三相分离器加高含水分析仪计量油田的单井产量．用微型计算机实现数据采集，模型求解和报表输出．为了降低成本，简化操作，不使用ＣＲＴ，而是利用微机上的数码管显示器，喇叭和仅有的两个按键实现人机交互。测量软件用ＴｕｒｂｏＣ语言编写。实际运行表明，该装置取代了人工量油，并提高了数据的可靠性。 This article describes the use of three-phase separators to increase the water content of single-well oil production measurement. Using microcomputer to realize data acquisition, model solving and report output. In order to reduce costs, simplify operation, do not use CRT, but the use of digital tube display on the computer, speakers and only two buttons to achieve human-computer interaction. Measurement software written in TurboC language. The actual operation shows that the device replaces the artificial oil and improves the reliability of the data.
