摘　　要：为解决人工添加固井堵漏材料劳动强度高、精度差和混合均匀度低等问题,开发以料仓、皮带计量和软管式螺旋输送机等为主要部件的固井堵漏材料自动化计量添加装置。设计以PLC为核心,触摸屏为人机交互界面,以料位计、变频器、称重传感器、变频电机为主要硬件,采用专家PID控制策略,实现信号采集、逻辑控制和数据通讯。进行纤维料3~5 kg/min,片状料10~50 kg/min极限输送的自动化测试,材料可以通过软管式螺旋输送机实现持续混合搅拌,和任意位置的均匀稳定投送,满足片状料、纤维料2类材料在仓内的下料计量和输送。测试结果显示,材料混合均匀度好,人工参与度少,计量精度稳定且误差<±1%;与人工相比,综合效能提高2倍以上。研究为海洋石油钻井平台自动化作业提供支撑。To solve the problems of high labor intensity,poor accuracy,and low mixing uniformity in manually adding cementing and plugging materials,an automated metering and adding device for cementing and plugging materials was developed,mainly consisting of silos,belt metering,and hose spiral conveyors.The device was designed with PLC as the core and touch screen as the human-machine interaction interface.The main hardware includes a level gauge,frequency converter,weighing sensor,and variable frequency motor.The device adopts an expert PID control strategy to achieve signal acquisition,logic control,and data communication.Through automated testing of extreme conveying of fiber materials at 3~5 kg/min and sheet-like materials at 10~50 kg/min,the material can be continuously mixed,stirred,and uniformly and stably delivered at any position through a hose type screw conveyor,meeting the requirements for feeding measurement and conveying of two types of materials,including sheetlike materials and fiber materials,in two silos.The results show that its mixing uniformity is good,with less manual participation,stable measurement accuracy,and an error of less than±1%;Compared to manual labor,the overall efficiency is two times higher.The research provides a support for automated operation of offshore oil drilling platforms.
