PATTERN MATCHING TO DETECT DEFECTS IN ROD LIFT DOWNHOLE CARDS

摘要

Data characterizing a load on a rod of a down-hole pump at different positions of a stroke of the rod can be received. An image characterizing the load of the rod at the different positions of the stroke can be determined. A defect in operating conditions of the down-hole pump can be determined. The determining can include comparing the image to a set of predetermined images with associated defects. The determined defect can be provided.
