Problems solved by technology

Although the above-mentioned utility model has improved the cutter, it still has not completely solved the problem of the incision, and still has an impact on the fluid output of the coiled tubing, which partially offsets the advantages of large and stable fluid output of the coiled tubing
[0004] Therefore, for the four-ram blowout preventer with inline cuts that have been widely used in the oil field, this inline cut has seriously affected the liquid output or gas output of coiled tubing. There are some toxic gases in the pipeline, such as hydrogen sulfide, carbon monoxide, etc., and the energy of the formation is uncertain. Some oil and gas wells have high formation energy. Simply opening the four-ram blowout preventer to repair the cut may cause poisoning that is easy to operate However, it is easy to cause safety accidents such as blowout and overflow of high-pressure wells. Therefore, there is no special repair tool that can complete the repair work of the above-mentioned tubing cuts. Therefore, it is necessary to design a special repair device for straight cuts. Make a safe fix

Embodiment 1

[0029] Embodiment 1, with reference to attached Figure 1-3 , a coiled tubing incision recovery repair device mentioned in the present invention, its technical solution is: including the repair port outer jacket 7, repair port inner mold 8, support spring 9, key sleeve 10, transition connection sleeve 11, connecting bolt 12, upper pressure Cap 13, single-flow valve sealing steel ball 14, single-flow valve inlet ball seat 15, wherein the four-ram packer includes four-ram BOP body 2, half-sealed ram 3, suspension ram 4, shear The ram 5 and the fully-sealed ram 6 are provided with a coiled tubing 1 in the oil well, and the end is a straight cut a cut by the shear ram 5 . The transition connecting sleeve 11 is connected with the upper joint 19 of the four-ram blowout preventer through an internal thread, the upper part of the transition connecting sleeve 11 is connected to the upper pressing cap 13 through the connecting bolt 12, and the key sleeve 10 is placed under the upper pre...

Embodiment 2

[0043] Embodiment 2, the difference between the present invention and Embodiment 1 is that the bottom of the repair mouth cover 7 can be provided with an L-shaped groove, and the two extruding ends of the incision can still be grasped, and then lifted, and at the same time pass Reaming extrusion of the notch by the conical structure.

Embodiment 3

[0044] Embodiment 3, the difference between the present invention and Embodiment 1 is that a bearing can be provided between the repair port outer cover 7 and the repair port inner mold 8 of the present invention, so that the rotation is easier and the operation is more labor-saving.

Abstract

The invention relates to a device for restoring and repairing cuts of coiled tubing. The technical solution is: the upper part of the transitional connection sleeve is connected to the upper pressure cap through the connecting bolt, the key sleeve is placed under the upper pressure cap, the key sleeve is provided with an inner key groove, and the inner key groove is matched with the outer key of the repair port jacket, and the repair port jacket is The lower part is provided with a T-shaped groove, and the bottom of the inner mold of the repair port is a cone structure, and is provided with a plurality of air injection holes, through which the air injection holes communicate with the one-way valve in the inner cavity of the inner mold of the repair port, the beneficial effect is: The cooperation of the plate and the transitional connection sleeve, key sleeve, repair port jacket, repair port inner mold and upper pressure cap effectively controls the toxic gas, avoids a large amount of leakage, and also avoids self-spray or overflow, and realizes The reaming and repairing of the straight incision greatly increases the liquid output or gas output, solves the current problems in the use of coiled tubing, and further promotes the application of coiled tubing.

Description

technical field [0001] The invention relates to a wellhead repairing device in the petroleum industry, in particular to a coiled tubing cut restoration and repairing device. Background technique [0002] With the continuous development of coiled tubing technology, the development and application of coiled tubing oil recovery or coalbed methane technology has been promoted. The existing coiled tubing has good flexibility. A roll of coiled tubing is several kilometers long and can replace conventional tubing for many operations. , The coiled tubing operation equipment has the characteristics of pressure operation, continuous lifting, small equipment size, fast operation cycle and low cost, and is especially suitable for the exploitation of self-flowing wells. Among them, the coiled tubing four-ram blowout preventer plays a pivotal role in coiled tubing operations and belongs to a special wellhead blowout preventer. The existing coiled tubing four-ram blowout preventer includes...
