Description

Technical Field

[0001] The utility model relates to the technical field of hydraulic sealing, in particular to a capillary hydraulic sealing tool. Background Art

[0002] Hydraulic seating is one of the main seating methods of the packer. When using the packer to seal the inside of a capillary pipe, the packer must first be inserted into the capillary. Then the hydraulic seating tool on the upper end of the packer drops a steel ball into the packer. After that, hydraulic oil is filled into the packer through the hydraulic seating tool. The hydraulic pressure applies force to the ball seat through the steel ball, which indirectly causes the packer rubber cylinder to be radially deformed. The deformed rubber cylinder fits perfectly with the inner wall of the capillary, thereby sealing the capillary.

[0003] The operating sequence of the hydraulic seat seal is to first release the steel ball and then pump in the hydraulic oil. If an error occurs and the hydraulic oil is pumped in first, the steel ball may break the support plate that controls the release of the steel ball under the action of the hydraulic pressure, thereby causing damage to the internal part of the equipment. Therefore, we need a new capillary hydraulic seat seal tool that can prevent this error. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figures 1 to 4In the embodiment of the utility model, a capillary hydraulic sealing tool comprises a cylinder 1, a liquid injection cavity 2, a liquid inlet 3, and a steel ball 4. Slide grooves 5 are provided on both sides of the lower inner wall of the liquid injection cavity 2. A first chamber 9 is provided on the inner end wall of the slide groove 5. A connecting groove 11 is provided on the upper inner wall of one of the first chambers 9 on one side, which is close to the liquid injection cavity 2. The connecting groove 11 extends upward through the lower inner wall of the second chamber 19. The second chamber 19 is provided inside the upper part of the side wall of one end of the liquid injection cavity 2. Anti-misoperation components are provided in the inner cavities of the slide groove 5, the first chamber 9, the connecting groove 11, and the second chamber 19;

[0027] The anti-misoperation assembly includes a support control unit having a support plate 6, a linkage unit having a connecting rod 10, and a baffle unit having a baffle 18;

[0028] The support plate 6 is used to control the placement of the steel ball 4, and the baffle 18 is used to control whether the hydraulic oil can be poured into the injection chamber 2;

[0029] The connecting rod 10 is used to ensure that when the two supporting plates 6 are opened away from each other, the baffle 18 is in a rotated open state, and when the two supporting plates 6 are in a close closed state, the baffle 18 is in a flat closed state.

[0030] In this embodiment: it should be noted that: in the initial state, the two support plates 6 are in a state of being close to each other, the upper end of the support plate 6 supports the steel ball 4, and the baffle 18 is in a 180-degree horizontal closed state;

[0031] When the sealing tool is used to seal the packer in the capillary, the staff controls the output shaft of the micro motor 8 to rotate, thereby driving the micro screw 21 to rotate. The sliding table moving on the micro screw 21 drives the supporting plate 6 to slide into the inner cavity of the slide groove 5 through the connecting block 7. At this time, the steel ball 4 is no longer blocked by the supporting plate 6, so it passes through the injection cavity 2 and falls smoothly onto the ball seat at the bottom end of the packer.

[0032] During this process, the connecting block 7 moves along the first chamber 9 toward the direction close to the micro motor 8, the connecting rod 10 on the connecting block 7 moves in the connecting groove 11 toward the direction away from the injection chamber 12, and the rack 12 at the upper end of the connecting rod 10 also moves synchronously;

[0033] The moving rack 12 drives the gear 13 to rotate, and the rotating gear 13 drives the second bevel gear 16 to rotate through the first rotating shaft 14 and the first bevel gear 15, and the rotating second bevel gear 16 drives the baffle 18 to rotate to a state of 90 degrees, at which time the baffle 18 no longer blocks the upper end opening of the injection chamber 2, so that the hydraulic oil can enter the injection chamber 2 through the liquid inlet 3;
