Patent ID: 11608714

Abstract:
A switch sliding sleeve device for oil-gas exploitation and switching method thereof, an oil-gas exploitation tool and a switching method of a wall through hole thereof are disclosed. The disclosure relates to the technical field of oil-gas exploitation, and solves the technical problems in the prior art that the switching operation steps of a wall through hole of an outer cylinder are tedious and complex, and a large amount of manpower and material resources are consumed. The switch sliding sleeve device for oil-gas exploitation and the oil-gas exploitation tool include an outer cylinder, a switch sliding sleeve mechanism and a trigger. When the trigger is put into the outer cylinder and punching triggers the switch sliding sleeve mechanism, the switch sliding sleeve mechanism is capable of being switched from a state of opening the wall through hole to a state of closing the wall through hole until is triggered by the trigger or another trigger again. The switching method of the wall through hole of the oil-gas exploitation tool includes the following steps: putting a trigger into the outer cylinder to open the wall through hole, and putting the trigger into the outer cylinder again to close the wall through hole. Thus, the switching operation of the wall through hole is facilitated, and the operation cost is reduced.
