摘　　要：抽油机冲程、冲次是绘制抽油机示功图、计算抽油机平衡率的重要参数。通过加速度传感器测量冲程、冲次,避免了传统拉线式、角度式等方法故有的故障率高、操作繁琐、需要停井等缺点,具有自动化、不影响生产等特点。采用单轴加速度传感器测量抽油机冲程误差较大,而该项目使用三轴加速度传感器,并采用新技术、新算法,能够精确测量抽油机冲程、冲次,而且可以将数据远传至智能终端,因此该项目具有重要的研究意义和应用价值。The pumping speed and stroke of the pumping unit are important parameters for drawing the indicator diagram of the pumping unit and calculating the balance ratio of the pumping unit.The measurement of the pumping speed and the stroke by acceleration sensor can avoid the disadvantages of the traditional wire-drawing type and the angle type,such as high failure rate,cumbersome operation,and need to stop the well,and has the characteristics of automation and no influence on production.There is a large error in the measurement of pumping speed and stroke with single-axis accelerometer.The project uses a three-axis accelerometer and adopts new technology and new algorithm to accurately measure the pump speed and stroke,and can transfer the data to the intelligent terminal,so the project has important research significance and application value.
