摘要
为了解决高气液比油井气液比高、生产稳定性差而难以精确计量的难题,研制了适合高气液比计量的三相自动计量装置。该装置采用两级分离和旋流预分离器双入口设计,分离效果好、抗波动性强;实现了装置的小型橇块化,可设为车载式或固定式,扩大了适用范围;控制系统采用RTU作为数据控制模块,计量过程完全自动化,无需人工操控,采用GPRS数据传输模块可实现计量数据远传至中心服务器;采用连通管原理,配套高精度液位计,实现了产液和含水率同时计量。在高气低液单井、高液低气单井以及间出井等不同工况下开展单井现场应用,结果表明:高气液比三相自动计量装置不仅计量结果稳定、精度高,且对间出井等特殊工况适应性好,产气量、产液量、含水率计量值的相对误差分别低于10%、2%、5%。(图1,表3,参6)。
It is difficult to accurately measure the parameters of high gas-liquid ratio wells due to their high gas-liquid ratio and poor operation stability. To solve the problem, a three-phase automatic metering device for metering high gas-liquid ratio has been developed. The device with two stage separator and cyclone pre-separator double entry design has good separating effect and high anti-volatility. The device is small in size and skid-mounted and can be mounted on vehicle or installed in field, allowing its application in a wider range of conditions. With RTU as the data control module in the control system, the metering process is fully automatic without manual control, and GPRS date transmission module allows the remote transmission of metering data to a central server. Based on connecting pipe theory and equipped with precise liquid level meter, the liquid production and water content can be measured simultaneously. The field application on high gas- liquid ratio wells, low gas-liquid ratio wells and intermittent wells shows that the high gas-liquid ratio three-phase automatic metering device is not only stable and highly accurate, but also adaptable to special working condition of intermittent wells. The relative errors of gas production, liquid production and water content measured are less than 10%, 2% and 5% respectively. （1 Figure, 3 Tables, 6 References）
