计算机诊断技术的理论基础。使用计算机绘出地面示功图、井下示功图及减速箱扭矩曲线图,并计算出抽油装置(包括电动机、抽油机、抽油杠及深井泵)多项定量数据。通过使用新型电子动力仪和微型计算机对大量抽油井的现场诊断表明,此项技术有助于准确诊断深井泵故障及全面掌握抽油设备的使用情况。目前,我国已具备推广此项技术的各种条件。 The theoretical basis of computer diagnosis technology. Use the computer to draw the ground dynamometer, underground dynamometer and gearbox torque curve, and calculate the pumping unit (including motor, pumping unit, pumping rod and deep well pump) a number of quantitative data. Field diagnostics of a large number of pumping wells using the new electronic dynamometers and microcomputers show that this technique can help accurately diagnose deep well pump faults and fully grasp the use of pumping equipment. At present, China has all the necessary conditions to promote this technology.
