China Remanufacturing technology helps oil field production

• At the end of February, jidong oilfield machinery remanufacturing company completed pumping units 72 units, saves money for oil of more than 10 million Yuan.
  In recent years, with reservoirs further incline, directional wells in jidong oilfield more of downhole pump depth increase. In order to slow down the rod and tube partial wear and improving pump efficiency, production processes need to switch to a low stroke pumping unit with long stroke, causing some in the short-stroke, low torque pumping idle due to oil production requirements are not met. Meanwhile, some of the longer-running unit, due to components wear, aging equipment, failure is much more, updated maintenance difficulties and other factors need to be scrapped, much larger cost burden for oil.
  Jidong oil field beginning in 2012 to begin pumping "remanufacturing" research, waste recycling, dismantling of pumping units, on the basis of performance evaluation and life, remanufacturing engineering and maximize idle scrap unit of resource potential. Scientific and technical personnel through technical innovation, application of new technologies such as motor drives, power feedback, make long strokes, big torque under the barbell and energy saving beam pumping unit, stroke and torque not only meets the needs of oilfield production and remanufacturing low stroke pumping units and gives good energy-saving performance.
  So-called remanufacturing, is based on an old machine for blanks, using special techniques and technologies, on a new original manufacture based on manufacturing. Application through design innovation and a range of new technologies, manufacturing unit of new pumping unit standards for reliability, service life is reached, use has much better performance than the original pump.
  It is understood that the base of the old pumping units, frame, gear box and crank, balancing blocks, connecting rods, bearings and other components and through improving the maintenance of the best possible reuse, even under the old donkey head was also converted into a barbell, 72 cumulative savings over more than 1000 tons of steel manufacture pumping unit, significant economic and social benefits.
