Invention relates to means for monitoring and control of objects for oil extraction, in particular pumping units, for matching productivity of well rod pump and bed productivity, and can be used in oil producing industry. Specific point of the method proposed for control of electric drive of well rod pumping unit is in fact that there for determination of coefficient of filling of pump as informative parameter one uses current of drive motor. Such approach removes error of measurement of force in polished rod, this substantially affects increase of accuracy of control of electric drive of rod well pumping unit and decreases operation expenses. |
