Background technology
Long working is carried out, it is necessary to which coiled tubing is put into well when carrying out the operations such as well logging and heavy crude heat extraction, together
When, there are multiple wells job requirements simultaneously again.Current operating type could be incited somebody to action, it is necessary to coiled tubing is all proposed from well
Equipment removes next well head and carries out operation, in order to meet that it is same that coiled tubing is placed on operation and multiple wells in well for a long time simultaneously
Shi Zuoye operating mode needs, it is necessary to removes equipment using more sets, cost is high, and utilization rate of equipment and installations is low.Such as coiled tubing is protected
Hold in well, and enable a device to remove, it is necessary to block coiled tubing, the coiled tubing being truncated is difficult to be applied to it
In his well, the consumption of resource is indirectly caused, adds operating cost.
The content of the invention
The present invention is directed to above-mentioned the shortcomings of the prior art, it is proposed that a kind of construction work of continuous oil pipe operation sledge group
Skill.
The construction technology of the continuous oil pipe operation sledge group of the present invention, the continuous oil pipe operation sledge group include oil pipe roller
Sledge, injection head sledge and well control device, the oil pipe roller sledge include roller sledge frame and roller, and the roller is removably mounted on
On roller sledge frame；The injection head sledge includes injection sledge frame, injects on sledge frame and installs the injection head main body and gooseneck of opening type；Apply
Work processing step is as follows：
1) operation sledge group is installed：Well control device is installed on wellhead assembly, and injection head sledge is installed to above wellhead assembly, will
The drive device of drive device and oil pipe roller sledge on injection head sledge is by controlling cable and hydraulic line online.
2) coiled tubing injects：Coiled tubing is removed from roller, then passes sequentially through gooseneck, injection head main body and well
Device is controlled, underground is sent to by wellhead assembly, the drive device Driver injection head main body on injection head sledge, carries out coiled tubing
Remove.
3) coiled tubing is fixed：After coiled tubing is put into underground setting position, between well control device and roller
Coiled tubing both ends installation oil pipe geometrical clamp, coiled tubing and well control device and roller are fixed.
4) operation sledge group removes：Injection head main body is opened, and injection head sledge is removed from wellhead assembly, takes roller sledge frame apart
Bindiny mechanism, roller sledge frame is removed.
Preferably, the drive device Driver injection head main body on injection head sledge, the process removed of coiled tubing is carried out
In, the drive device driving drum of oil pipe roller sledge provides opposition, and coiled tubing is tensioned.
Preferably, after operation sledge group removes, roller is placed on roller holder, the company between roller and well control device
Continuous oil pipe freely hangs placement.
Preferably, before coiled tubing injection, when carrying out operation sledge group installation steps, injection head sledge is installed to well
The side of mouth device, the gooseneck of injection head sledge are located above wellhead assembly；When carrying out coiled tubing implantation step, roller is left
Coiled tubing is directly conveyed towards well control device by gooseneck, and is sent into underground, the drive device of oil pipe roller sledge by wellhead assembly
Driving drum, carry out removing for coiled tubing.
Preferably, after the removal of operation sledge group, roller is installed onto on roller sledge frame, and injection head sledge is installed into well head
The side of device, the gooseneck of injection head sledge are located above wellhead assembly, and the coiled tubing between well control device and roller is placed into

Coiled tubing removes.
The beneficial effects of the invention are as follows：The construction technology of this continuous oil pipe operation sledge group can carry out rising for coiled tubing
Under, while coiled tubing, in the case where not being truncated, operation sledge group is extensible to carry out operation, operating flexibility to other well heads
By force, utilization rate of equipment and installations is high, and operational reliability is strong, more meets the needs of operation field, equipment usage quantity is few, operation cost
It is low, without coiled tubing is destroyed, the consumption of coiled tubing is alleviated, further reduces cost.
Before equipment is removed, coiled tubing is fixed above well control device using oil pipe geometrical clamp, avoids coiled tubing from falling
Well, coiled tubing is fixed above roller using oil pipe geometrical clamp, ensure that coiled tubing does not relax on roller, be easy to again
The rountrip that equipment carries out coiled tubing is installed.
The process removed of coiled tubing, the drawing of injection head main body and the acting in opposition of roller, make coiled tubing
Do not relax tightly, when ensureing coiled tubing rountrip, the fluency of operation.
Under the operating mode of oil equipment has been installed above without using injection head folding and unfolding oil pipe or wellhead assembly, oil pipe rolling
The roller of cylinder sledge can provide enough moments of torsion, overcome the deadweight of OIH pipe, can also carry out the rountrip of coiled tubing,
Realize the operation under various working, strong adaptability.
