| titleOfInvention | METHOD AND DEVICE FOR CONTROLLING THE OPERATION OF A WELL PUMPING SYSTEM |
| abstract | THE INVENTION RELATES TO PUMPING TECHNIQUES FOR OIL WELLS. A DEVICE INTENDED TO DETECT A STUCK CONDITION ON THE FLUID IN A PUMPING PLANT FOR AN OIL WELL USES POSITION VALUES OF THE ROD TRAIN 16 AND THE LOAD ON THE ROD TRAIN TO CALCULATE A REFERENCE POSITION AND A VALUE OF SELECTED LOAD. THE DEVICE PERFORMS A CONTINUOUS UPDATE OF THE REFERENCE POSITIONS AND SELECTED LOAD VALUES TO COMPENSATE FOR A DRIFT IN THE CHARACTERISTICS OF TRANSDUCERS 47, 53 USED TO DETERMINE THE LOAD AND THE POSITION OF THE RIGGED GEAR. A WARNING SIGNAL APPEARS WHEN THE ACTUAL LOAD EXCEEDS THE SELECTED VALUE WHEN THE ROD TRAIN REACHES THE UPDATED REFERENCE POSITION, IN THE DOWNSTROKE. APPLICATION TO OIL PRODUCTION. |
