When the deep water turbine hydraulic internal cutting tool works, after the deep water turbine hydraulic internal cutting tool is lowered to a designated position, a pump is started, and pumped high-pressure liquid enters the turbine torque device 1 through the upper joint 5. The high-pressure liquid entering the turbine torque device 1 is split by the splitter 6 and then impacts the turbine rotor 9 so as to drive the main shaft 7 to rotate; the spindle 7 thereby rotates the torque transmission device 2, the supercharging device 3 and the sleeve cutting device 4 via the coupling 15.
While the torque transmission device 2, the supercharging device 3 and the sleeve cutting device 4 rotate, high-pressure liquid which is impacted on the turbine rotor 9 enters the torque transmission device 2 through the liquid flow holes on the guide ring 12, the communication holes 17 and the central hole on the main shaft 7.
The high-pressure liquid entering the torque transmission device 2 is collected in the central tube 20 and enters the sealing cavity 46 between the slips 19 and the central tube 20 through the pressurizing hole 21, and then continuously enters the sealing cavity 46, under the action of the pressure, the slips 19 are pushed to move towards the outer tube 41 end by the high-pressure liquid, and the claws 45 of the slips 19 are gradually spread out until the slips 19 are contacted with the inner wall of the tubular column and anchored on the tubular wall in the process of moving towards the outer tube 41 end due to the conical outer tube 41; thereby integrally fixing the tool; as the center tube 20 of the torque transmitting device 2 is threadedly connected to the casing anchor upper sub 18; the outer tube 41 is movably arranged on the central tube 20 through the baffle ring 42 and the rotary bearing 43, the slips 19 are in sliding connection with the outer tube 41, the outer tube 41 is in sliding contact connection with the sleeve anchor upper joint 18, and the outer tube 41 and the slips 19 can not rotate along with the central tube 20 in working engineering.
After the high-pressure liquid collected in the central tube 20 reaches a certain pressure, the piston 23 is pushed to move along the mounting straight rod 26, so that the state that the piston 23 is in sealing contact with the port of the step hole is released, and the high-pressure liquid enters the supercharging device 3. The purpose of the pressurizing means 3 is to force the high-pressure liquid to build up a hold-down pressure in the torque transmitting means 2, so that the high-pressure liquid entering the pressurizing means 3 must reach a sufficient pressure. When the high-pressure liquid pressure in the torque transmitting device 2 is insufficient to compress the elastic force of the spring 24, the piston 23 is restored under the action of the spring 24, and the piston 23 and the stepped hole port are sealed again.
The high pressure fluid entering the pressurizing means 3 enters the casing cutting device 4 through the annulus between the flow port 28, the fitting seat 25 and the housing 22.
Part of the high-pressure liquid that enters the casing cutting device 4 is discharged through the center hole of the push rod 32, the liquid flow hole 37 and the lower joint 30, and the other part of the high-pressure liquid acts on the end face of the push rod 32 and the push rod 32 moves axially.
In this process, the push rod 32 first shears the shear pin 38; during the movement, the compression spring 33 is compressed, and the cutter 36 is pushed to be gradually opened, so that the sleeve is contacted to realize cutting. The spring piece 35 is simultaneously extruded to store energy in the process of gradually expanding the cutter 36.
As the push rod 32 moves, the cutting depth of the cutter 36 increases, and when the cutter 36 cuts the sleeve completely; the central hole port of the push rod 32 and the end of the limit valve rod 21 are just in a completely embedded state, and the baffle 39 and the cutter 36 form a contact state.
In the moving process of the push rod 32 of the sleeve cutting device 4, the distance between the push rod 32 and the limit valve rod 21 is gradually reduced, namely, the valve port flow area formed at the end of the central hole port of the push rod 32 and the end of the limit valve rod 21 is gradually reduced, and the pressure drop at the valve port is gradually increased. When the sleeve is completely cut off by the cutter 36, the port of the central hole of the push rod 32 and the end head of the limit valve rod 21 are in a completely embedded state, the flow passage of high-pressure liquid is cut off at the same time, the bypass hole 40 is communicated with the central hole of the shell 29 due to the movement of the push rod 32, when the flow passage of the high-pressure liquid is cut off, the high-pressure liquid enters the annular space between the shell 29 and the sleeve through the bypass hole 40, at the moment, the pressure of the pumped high-pressure liquid is changed, and the ground can accurately judge whether the sleeve is completely cut off according to the pressure change; accurate, visual, convenient and reliable, and can avoid erroneous judgment.
After the cutting operation is completed, the pressing is stopped, the push rod 32 and the cutter 36 are reset successively under the action of the spring piece 35 and the compression spring 33, the pipe column is lifted, and when the pipe column is lifted, the outer pipe 41 and the slips 19 are in sliding friction, so that relative displacement is generated between the outer pipe 41 and the slips 19, and the slips 19 are reset.
The housing 29 of the deep water turbine hydraulic internal cutting tool is a reducing body, and can play a role in righting through the cooperation of the housing 19 and the slips 19, so that the cutting stability of the tool can be improved, and the service life of a cutter can be prolonged.
