Abstract
The utility model discloses a quick coiled tubing pressure-welding connecting device, and belongs to the technical field of oil fields. A first hydraulic power push block and a second hydraulic power push block are respectively in the shape of a regular hexagon. A trefoil pressure-welding connector is solid, bar-shaped pressure-welding connectors are provided with first annular pressure-welding grooves, second annular pressure-welding grooves and limiting clamps, and the limiting clamps can catch a deformed coiled tubing due to the stepped shape of the limiting clamps. Due to the cable partitioning structure of the trefoil pressure-welding connector and the stepped shape of the annular grooves, the deformed coiled tubing can be caught. The quick coiled tubing pressure-welding connecting device has the advantages that it can be guaranteed that the situation that cables between a well mouth and a testing control console lose efficacy due to high temperature generated by electric welding cannot occur, the technological difficulty is lowered and the construction speed is increased.
Description
Technical field
The utility model relates to the quick press-contact connection apparatus of a kind of coiled tubing, belongs to oilfield technology field.
Background technology
Coiled tubing is a kind of flexible continual minor diameter tubing that has, in SAGD oil field, conventional long coiled tubing built-in testing instrument is transferred to and in well, is carried out temperature, press the operations such as test, on the injection head that uses while the carrying coiled tubing squeezing structure that is chain track type, four legs fix on the ground and support, top injection head coordinates stiction that motor produces to make it regain Operation Tubing Aggregate with chain crawler belt, because injection head chain caterpillar belt structure is fixing non-adjustable, if coiled tubing is greater than its original diameter, just cannot or damage machine by injection head, therefore must connect upper and lower two coiled tubing joints by the form of electric welding, but be made with so following 3 shortcomings:
1, the instrument of coiled tubing the inside or ground residue cable cannot bear the high temperature that electric welding brings and cause damaging, and are again lowered to the test cable that need to cut out damage, have so just caused the deep-seated that can test to be set up and have moved.
2, need on-the-spot consumer, need professional electric welder, operation is more complicated, and once welding needs the construction of half an hour, and the weld bond of need to polishing.
3, upper and lower two coiled tubings are not easy to welding with one heart together, after welding, can produce fracture because of the stress that injection head tilts to produce when not drawing, cause the trouble of construction again.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of coiled tubing quick press-contact connection apparatus.
The quick press-contact connection apparatus of a kind of coiled tubing, the first hydraulic power pushing block, the second hydraulic power pushing block adopt regular hexagon; Trilobal crimping connector is solid, and clavate crimping connector has the first annular crimp groove, the second shape crimp groove and limiting card, and the step shape of limiting card can tangle the coiled tubing of distortion; Trilobal crimping connector is separated the structure of cable and the stepped ramp type of annular groove thereof and can tangle the coiled tubing of distortion; Operation Tubing Aggregate loads cable dish recovering tray, crawler belt iron chains and injection head stube cable pipe, underground continuous oil pipe stube cable, underground continuous oil pipe from well head along enter, stablize seat supports crawler belt iron chains and injection head, hydraulic pump connects the first hydraulic power pushing block, the second hydraulic power pushing block.
The quick crimping connection method of a kind of coiled tubing, contains following steps;
On put forward process steps: injection head is connected to bearing and is steadily placed on well head top; injection head forward is stretched out and is carried joint; the ground residue cable of underground continuous oil pipe is filled in and carried joint; then with on propose joint butt welding, polishing utilizes after soldering opening the reversion of injection head hydraulic system to propose underground continuous oil pipe;
Clavate crimping connector can be assisted coiled tubing coaxial step with one heart up and down, limiting card makes upper and lower coiled tubing move to relevant position to stop, annular crimp groove is can tightly link together with crimp head after coiled tubing distortion in order to make, can crimping the joint of twice be to use for the super dark well of overlength, crimping can produce larger pulling force twice
Crimp head makes coiled tubing with one heart coaxial up and down, and limiting card can tangle device at coiled tubing place, and this three-vaned device has used solid mode, is applicable to manage the coiled tubing crimping of interior 3 cables; Hydraulic pump uses foot-operated supercharging, after crimping, can produce the pressure of 60 tons-100 tons by pressure release taking-up pushing block die head, is enough to compressive strain coiled tubing joint;
Also contain following steps;
After step 3, crimping, use and on injection head, carry underground continuous oil pipe;
Step 5, proposition steel pipe and joint, expose cable.
The external diameter of coiled tubing is in about 32mm, and wall thickness is in 3mm left and right, is not lowered to 500-1000 rice not etc. in oil well, and 3-4 testers are generally contained in inside, and most of tester is cut off rear inefficacy and cannot be born high temperature.
Underground continuous oil pipe welding and on carry in incidental situation have: the cable internal insulating layer that the high temperature in welding process destroys instrument causes instrument to lose efficacy, on carry in process because top connection and lower contact have low-angle can cause the stress of welding position to concentrate and produce fracture, after welding position overheap, cannot pass through injection head.
The utility model has the advantages that the cable that can guarantee between well head and test console can not lose efficacy because electric welding produces high temperature, reduce technical difficulty, improve speed of application.
