Definitions

  • the invention relates to a packer, in particular to a pumping oil-absorbing type petroleum packer, belonging to the technical field of petroleum machinery.
  • the packer In the oil recovery project, the packer is used for stratification, and the oil collector is designed on the packer.
  • the piston sleeve When the seal is set, the piston sleeve is up and the oil production passage is opened. After the seal is placed, the upper layer pressure acts on the balance piston and pushes the rubber cylinder upward.
  • the unsealing pin is protected from shearing force; when unsealing, the friction pin of the rubber tube and the sleeve is used to cut off the unsealing pin, the piston sleeve is descended, the oil collecting passage is closed, and the oil plugging device is prevented from blocking the water construction process, which can be conveniently
  • the utility model can realize the non-pressure well not discharging operation, and can withstand high pressure in both directions and has a long service life.
  • the skin packers commonly used in oil fields are self-sealing.
  • the outer diameter of the cup is larger than the inner diameter of the sleeve, and the interference between the cup and the sleeve is used to achieve the sealing of the packer.
  • the resistance is large, and the cup is easily worn and scratched, thereby losing the sealing property.
  • thick oil layer digging potential is imperative, and also puts higher requirements on the downhole packer.
  • the existing packer is attached to the central pipe wall due to crude oil during oil recovery. It is easy to cause blockage and it is difficult to clear, but the existing technology is difficult to overcome the above problems.

  • the cylinder connecting member is provided in a shape matching the cylinder.
  • the piston is slidably coupled to the inner wall of the pump.
  • the piston is made of a rubber material.
  • the sealing plug is a detachable sealing pin.
  • the utility model achieves the beneficial effects that the device is a pumping and oil-absorbing type petroleum packer, and the device increases the oil staining device in the central pipe on the existing packer, which can effectively prevent the pipe jam and increase the equipment.
  • the service life of the whole device is reasonable and easy to use. It solves the problem that the existing packer is easy to cause blockage due to the adhesion of crude oil to the wall of the central pipe during oil recovery.
  • Figure 1 is a schematic view of the structure of the present invention
  • the present invention provides a pumping oil-absorbing type petroleum packer comprising an upper joint 1 which is in communication with a central pipe 7 at the bottom thereof, and a pin 2 is provided on one side of the center pipe 7, and the bottom of the pin 2 is provided.
  • An adjusting ring 3 is arranged, one side of the adjusting ring 3 is provided with a first O-shaped rubber ring 4, the bottom of the adjusting ring 3 is provided with a rubber cylinder 5, the bottom of the rubber cylinder 5 is provided with a spacer ring 6, and the bottom of the spacer ring 6 is arranged There is a second O-shaped rubber ring 8, and one side of the second O-shaped rubber ring 8 is provided with a pressure receiving joint 9 on one side thereof, and a third O-shaped rubber ring 10 is disposed at the bottom of the pressure receiving joint 9
  • the bottom of the apron 10 is provided with a setting shearing nail 11 , and the bottom of the sealing shearing nail 11 is provided with a key 12 , the bottom of the key 12 is provided with a lower joint 13 , and one side of the key 12 is provided with a compression distance ring 14 , the center
  • the tube 7 is in communication with the suction tube 16 on the other side thereof.
  • the suction tube 16 is transversely inserted with a sealing pin 19.
  • the inside of the suction tube 16 is provided with a piston 17, and the piston 17 is fixedly connected with the cylinder connecting member 18 on the surface of the suction tube 16, and the suction tube One end of 16 A water outlet 15 is provided.
  • the cylinder connecting member 18 is provided in a shape matching the cylinder to facilitate connection of the transmission mechanism of the cylinder.
  • the piston 17 is slidably coupled to the inner wall of the suction drum 16 to facilitate piston movement within the suction cylinder.
  • the piston 17 is made of a rubber material to increase the friction with the cylinder diameter.
  • the sealing pin 19 is a detachable sealing pin that is easy to pull out when needed.
  • the device is a pumping and oil-absorbing type petroleum packer.
  • the column When the device is needed, the column is arranged at the required setting height when setting. Because the pressure joint and the upper joint 1 are connected with the tail pipe, with the bottom of the well as the fulcrum, the set shearing nail 11 is cut, the upper joint 1, the adjusting ring 3, the central pipe 7 and the key 12 are descended together, and the oil pipe and the sleeve are sealed. The annular space of the tube, when the tube is unsealed, the tube is taken up, the rubber tube is retracted, and the original shape is restored.
