摘要： Method and apparatus for entering control points relative to a dynagraph of a well pumping unit using the position of a beam and a pen holder of an XY plotter. The beam and/or the pen holder is physically moved to a desired location and an "enter" button is pressed to enter a value corresponding to an X or a Y position and another button is used to enter the other corresponding position value. The entered point is used to control operation of the well.

摘要： Method and apparatus for detecting problems in sucker-rod well pumps and for determining which type of problem occurs. A first transducer provides a signal representative of the load on a sucker-rod string and a second transducer provides a signal representative of the sucker-rod position. The load signal and the position signal are used to generate a dynagraph of rod load vs. rod position with the pump working normally. A working dynagraph is continually compared with the normal dynagraph and a working load signal is continually compared with a normal rod load signal to detect problems in the pumping system and to determine the type of problem detected if one does develop.

摘要： Method and apparatus for recording and subsequent playback of selected dynagraphs for wells employing sucker-rod pumping units to determine well faults which cause well shutdown. Calibration data from well monitoring equipment is stored in a first "endless tape" type of memory during calibration of the well and operation data from the monitoring equipment is stored in a second "endless tape" memory during well operation. After well shutdown the stored data can be retrieved and the operation data stored immediately prior to well shutdown compared with calibration data to determine what type of fault caused well shutdown.
