[0018] Beneficial effects of the present invention:

[0019] 1. Through the design of the telescopic shaft and the movable plate, when the mortar enters the installation box, the mortar impacts the movable plate, which can cause the movable plate to drive the telescopic shaft to contract, so that the pressure storage mechanism starts to store pressure.

[0020] 2. The present invention cooperates with the locking hole on the piston rod through the elastic locking block, so that the air in the inner cavity of the telescopic shaft can enter the elastic telescopic rod first. When the inner cavity pressure of the elastic telescopic rod reaches a certain level, the elastic locking block is squeezed so that the elastic locking block no longer restricts the piston rod.

[0021] 3. The present invention designs the protruding shaft A and the locking plate A. After the movable plate moves downward, the locking plate A limits the protruding shaft A, so that the telescopic end of the telescopic shaft can be kept stable, thereby keeping the inner cavity pressure of the sleeve and the elastic telescopic rod stable.

[0022] 4. The present invention designs the rotating plate and the limiting plate. When the blocking plate slides downward, the blocking plate rubs against the limiting plate to make the limiting plate slide downward, thereby limiting the rotating plate and preventing the rotating plate from resetting, which causes the blocking plate to interfere with the rotating plate when resetting.

[0038] It also includes a fixing frame A12, which is symmetrically fixed to the blocking plate 2, and an elastic telescopic rod 13 is fixed inside the fixing frame A12. The sleeve 9 is connected to the inner cavity of the elastic telescopic rod 13 through a hose (the hose is made of high-strength material and can withstand great pressure). The telescopic end of the elastic telescopic rod 13 passes through the blocking plate 2 and is fixed to a U-shaped plate 14. When the telescopic end of the elastic telescopic rod 13 moves, it drives the corresponding U-shaped plate 14 to move.

[0039] The impact mechanism includes a clamping plate 15, which is slidably connected to the U-shaped plate 14. The two clamping plates 15 abut against each other when moving.

An arc groove used in conjunction with the limit plate 221 is provided in the middle of the blocking plate 17, and when the arc groove of the blocking plate 17 contacts the limit plate 221, the friction force can drive the limit plate 221 to move.

[0042] It also includes a wedge block A23. The top end of the piston rod 10 is fixedly connected to the wedge block A23. One side of the elastic locking pin 21 is rotatably connected to a roller used in conjunction with the wedge block A23. The wedge block A23 is used to disengage the elastic locking pin 21 from the locking hole of the blocking plate 17.

[0043] When the jet radial drilling device in the prior art is in use, a high-pressure pump is used to provide high-pressure mortar to the hydraulic jet radial drilling device. After the high-pressure mortar passes through a pipeline that is several thousand meters long, its pressure will be greatly reduced, resulting in insufficient mortar pressure when the hydraulic jet radial drilling device is working, and poor drilling effect. The present invention can effectively solve the above problems, specifically:

[0044] When the nozzle 100 moves to the drilling position, the mortar is transported into the outer tube 1 through the high-pressure pump in the prior art, and the mortar enters the installation box 4 through the one-way valve 3 and impacts the movable plate 6. The movable plate 6 falls under the impact and drives the telescopic end of the telescopic shaft 5 to contract, and the movable plate 6 drives the protruding shaft A7 to fall. After the protruding shaft A7 falls, it contacts the inclined surface of the adjacent locking plate A8. The locking plate A8 slides horizontally under force, and the elastic member A between the locking plate A8 and the telescopic shaft 5 contracts. After the protruding shaft A7 continues to move, it no longer contacts and passes over the inclined surface of the locking plate A8. At this time, the elastic member A is released to drive the locking plate A8 to slide back to its original position. The locking plate A8 limits the movable plate 6 through the protruding shaft A7, so that the telescopic end of the telescopic shaft 5 no longer moves. At this time, the inner The cavity air enters the sleeve 9 through the transverse tube, and the piston rod 10 is pushed by the air. Since the elastic force of the elastic locking block 11 is large and the locking groove of the piston rod 10 applies force to the lower wedge surface of the elastic locking block 11, the air thrust received by the piston rod 10 cannot squeeze the elastic locking block 11 out of the locking groove, and the piston rod 10 remains stable. The air entering the sleeve 9 enters the elastic telescopic rod 13 through the hose, and the elastic locking pin 21 is inserted into the locking hole of the blocking plate 17 to limit the blocking plate 17. The blocking plate 17 limits the telescopic end of the elastic telescopic rod 13 through the U-shaped plate 14. At this time, the inner cavity pressure of the elastic telescopic rod 13 gradually increases. When the inner cavity pressure of the elastic telescopic rod 13 reaches a certain level, the air can no longer enter the inner cavity of the elastic telescopic rod 13 At this time, the thrust of the air in the inner cavity of the telescopic shaft 5 on the piston rod 10 increases, and the squeezing force of the locking groove of the piston rod 10 on the elastic locking block 11 increases. The elastic locking block 11 is forced to slide and shrink to the side away from the piston rod 10 and disengage from the locking groove of the piston rod 10. After the piston rod 10 is freed from the restriction, it slides upward to shrink the elastic member B. The piston rod 10 drives the adjacent rotating plate 22, the limiting plate 221 and the wedge block A23 to slide upward. After the rotating plate 22 slides, it contacts and squeezes the sliding shaft B19. Since the torsional force of the elastic member D is greater than the elastic force of the elastic member C, the sliding shaft B19 is forced to drive the corresponding guide frame 20 to slide upward. At this time, the elastic member C is forced to extend, and the guide frame 20 squeezes the convex shaft on the adjacent sliding shaft A18. The convex shaft is forced to drive the corresponding locking member through the sliding shaft A18. The plate 15 slides, and at this time, the two plywood 15 slide close to each other and abut against each other, and then the wedge block A23 contacts and squeezes the roller on the adjacent elastic locking pin 21, and the roller rotates under force and drives the elastic locking pin 21 to slide to the side away from the blocking plate 17 and disengage from the locking hole of the blocking plate 17. After the blocking plate 17 is freed from the restriction of the elastic locking pin 21, the U-shaped plate 14 can move. At this time, the inner cavity pressure of the elastic telescopic rod 13 is released, and the telescopic end of the elastic telescopic rod 13 falls rapidly and drives the plywood 15 to fall through the U-shaped plate 14. The two U-shaped plates 14 and the two plywood 15 exert a huge squeezing force on the mortar in the installation box 4, so that the mortar is sprayed with high pressure through the nozzle 100. At this time, the sliding shaft B19 is no longer in contact with the rotating plate 22. In the process of the two plywood 15 falling,Since the bottom surfaces of the two plywoods 15 are inclined toward each other, the reaction pressure generated by the mortar on the two plywoods 15 can make the two plywoods 15 always counteract each other, preventing the two plywoods 15 from separating when falling and causing pressure loss. The nozzle 100 sprays high-pressure mortar to drill holes. When the mortar in the installation box 4 is completely sprayed out, the two plywoods 15 are no longer subjected to the reaction force of the mortar. At this time, the elastic member C contracts and drives the guide frame 20 to slide and reset. The guide frame 20 drives the sliding shaft B19 to reset, and the guide frame 20 drives the sliding shaft A18 to slide and reset by squeezing the convex shaft, thereby driving the two plywoods 15 to open, thereby realizing the pressure storage and release of the pressure storage mechanism, and realizing secondary squeezing and pressurizing of the mortar through the pressure storage mechanism, so that the nozzle 100 sprays high-pressure mortar, thereby ensuring efficient drilling.

[0045] When the U-shaped plate 14 drives the closing plate 15 to fall, the U-shaped plate 14 drives the blocking plate 17 to slide downward in the guide groove of the installation box 4 and the fixing frame A12, thereby preventing the mortar from entering the installation box 4 and the fixing frame A12 and causing the mortar pressure to be lost, and the blocking plate 17 squeezes the rotating plate 22, and the rotating plate 22 is forced to rotate downward and be accommodated in the rectangular groove on the piston rod 10. At the same time, the arc groove on the blocking plate 17 contacts the surface of the limit plate 221 and applies friction force. The limit plate 221 is forced to slide downward in the sliding groove and limit the rotating plate 22, so that the elastic member D cannot drive the rotating plate 22 to reset.

[0046] Example 2

[0047] like Figure 1-Figure 9 As shown, it also includes a sliding shaft C24, and the sliding shaft C24 is symmetrically connected to the movable plate 6 in a sliding manner. An elastic member E is arranged between the sliding shaft C24 and the movable plate 6, and the elastic member E is a compression spring. A wedge block B25 is fixedly connected to the bottom end of the sliding shaft C24, and a protruding shaft B26 used in conjunction with the wedge block B25 is fixedly connected to one side of the locking plate A8. When the wedge block B25 contacts the protruding shaft B26, the locking plate A8 can slide horizontally.

[0048] When the movable plate 6 falls, it drives the sliding shaft C24 to fall, and the sliding shaft C24 drives the wedge block B25 to fall. After the wedge block B25 falls, there is a gap between it and the adjacent protruding shaft B26. After the U-shaped plate 14 falls, it contacts and squeezes the top of the sliding shaft C24. The sliding shaft C24 slides downward under the force and contracts the elastic member E, and the sliding shaft C24 drives the wedge block B25 to fall. After the wedge block B25 falls, it contacts and squeezes the protruding shaft B26. The protruding shaft B26 drives the corresponding locking plate A8 to slide horizontally. The elastic member A contracts under the force. After the locking plate A8 slides, it no longer contacts the protruding shaft A7. After the protruding shaft A7 is freed from the restriction, the telescopic end of the telescopic shaft 5 can move. At this time, the telescopic end of the elastic telescopic rod 13 contracts and drives the U-shaped plate 14 to reset. The U-shaped plate 14 drives the adjacent combined plate 15 and The blocking plate 17 is reset, and the blocking plate 17 drives the guide frame 20 to reset through the sliding shaft B19. At the same time, the elastic member B is released and drives the telescopic end of the piston rod 10 to reset. The telescopic end of the piston rod 10 drives the rotating plate 22, the limit plate 221 and the wedge block A23 to reset. When the limit plate 221 passes through the blocking plate 17, the limit plate 221 contacts the arc groove of the blocking plate 17, and the limit plate 221 slides upward due to friction. After sliding, the limit plate 221 no longer limits the adjacent rotating plate 22. The rotating plate 22 is released and rotated to reset through the elastic member D. At this time, the air in the inner cavity of the sleeve 9 and the elastic telescopic rod 13 returns to the inner cavity of the telescopic shaft 5. The telescopic end of the telescopic shaft 5 drives the movable plate 6 to rise and reset. The movable plate 6 drives the protruding shaft A7, the sliding shaft C24 and the wedge block B25 to reset, thereby completing the reset of the entire device.

[0049] A method for exploiting a carbonate reservoir using a jet radial drilling device comprises the following steps:

[0050] S1: The mortar is delivered to the outer tube 1 by a high-pressure pump in the prior art, and the mortar passes through the one-way valve 3 and impacts the movable plate 6, thereby causing the telescopic shaft 5 to contract, and the air in the inner cavity of the telescopic shaft 5 enters the sleeve 9 and enters the inner cavity of the elastic telescopic rod 13 through the hose;

[0051] S2: After sufficient pressure is accumulated in the elastic telescopic rod 13, the elastic locking block 11 is separated from the locking groove on the piston rod 10, and the piston rod 10 drives the rotating plate 22 to squeeze the sliding shaft B19, so that the two closing plates 15 are merged, and then the wedge block A23 squeezes the elastic locking pin 21, so that the elastic locking pin 21 no longer limits the blocking plate 17;

[0052] S3: The telescopic end of the elastic telescopic rod 13 drives the clamping plate 15 to squeeze the mortar through the U-shaped plate 14, so that the nozzle 100 sprays the mortar to drill holes.
