Research On The Direction-changing Transmission Technology Of Sucker Rod

Determination of the Growd Driving Auger Stem Pump Working System Modern oil production activities include sucker rod pump, electric submersible pumps, electric submersible pumps and other oil recovery methods. The sucker rod pump oil extraction is a common problem:The pump is put far away from the oil section where called vertical wells, pumps sunk low, efficiency of pump is low, the advantages of horizontal wells can not be reflected, and with the capacity to will be more difficult to reduce the subsequent production; The Pump down to the deep slope section, needs to install more centralizer, the friction load increases, and with the deviation angle increases, there will be strictly off valve, leakage, worn rod tube and other serious effects the efficiency of oil recovery, horizontal wells can not be the greatest potential to play.In this essay, this new oil production-horizontal wells screw pump technology is a combination of rod pumps and electric submersible pumps, etc. for the new technology, the motor placed at the wellhead, while the use of the screw hole pump rotating pumping means, which would address the maintenance problems; Because the motor is placed at the wellhead, which largely reduces the cost.
