- W4376471605 abstract "In view of the problems existing in the traditional downhole injection and production device for oil production, this paper puts forward the improvement. On the original basis, by setting the sealing disc and O-ring, the connection tightness between the production pipe and the external connecting pipe is improved, the problem of easy leakage in the production process is effectively solved, and the sealing plate, limit rod, movable plate and spring are added, It can effectively avoid the blockage caused by the accumulation of more oil in the gap at the connection and the slow pumping speed of the oil extraction pipe, and greatly improve the oil production efficiency. In addition, the improved function of the device is tested and verified through device installation experiment, reverse sealing experiment, live simulation experiment and opening and closing experiment." @default.
