METHOD, ANALYZER AND PUMPING SYSTEM FOR DETECTING AN OIL LEAK IN A WALKING BEAM WELL PUMP

摘要

Computer-implemented method for detecting an oil leak in a rod deep pump, wherein during a pumping movement of the rod (5, 10) by the borehole head (6) a stroke region is formed, which is detected by a camera (22) by an image sequence, and the following process steps are carried out:a) capture images of the image sequence with at least the stroke range of the boom;b) Detection of contamination in the lifting area of the rod relative to a known clean state for a particular image of the image sequence,c) Determine the position of the detected contamination for a particular image of the image sequence using the respective position of the rod,(d) Determine the change in pollution at the determined location via at least one pump cycle from the images of the image sequence;(e) Check whether the change in pollution exceeds a predetermined limit value and, if applicable, issue an oil leak warning.
