A kind of experimental method of quality connection, and in particular to continuous pipe flash butt welding method that can be used for produced on-site.
Background technique
Continuous pipe (Coiled Tubing, abbreviation CT) is that one kind can be wrapped in major diameter (being typically 1 m or more) reel
On, there is high-intensitive and high tenacity high-performance coiled tubing, single to be several kms, operating pressure, can up to 60 MPa
Continuous tripping in plays producing well progress operation.It is current state-of-the-art oil by the continuous pipe operation technique of core apparatus of continuous pipe
Gas field operation mode is widely used to during various oil field operations since it has many advantages, such as economical, safe and efficient.
Since China in 1977 introduces First coiled tubing unit, continuous pipe operation technique is gradually generalized to the country
The oil fields such as Sichuan, grand celebration, long celebrating, triumph and North China, job area is defeated etc. throughout well workover, complete well, volume increase, drilling well and pipeline collection
Aspect.It is continuous to manage as the coiled tubing unit and supporting operation facility of China's independent research promote and apply after 2007
Operation technique has also obtained very fast development, and the note application such as nitrogen drain and foam sand wash is promoted.Especially in recent years, continuously
Pipe operation technique gradually develops to drilling well, pressure break, deep-well, ultradeep well and horizontal well operating direction, to continuous pipe specification and intensity
More stringent requirements are proposed.As continuous pipe caliber increases, length increases, this just needs fragmented transport, then carries out joint connection in site.
In addition, will also result in the damage of continuous pipe during field operation, and the reparation after continuous tube field connection and damage is only logical
The mode for crossing butt welding is just able to achieve.Therefore, continuous tube field pipe-pipe butt welding is the key that must be solved in continuous pipe operation
One of technology.However, the manual TIG weldering production efficiency used when continuous pipe connection at present is low, at high cost, welding quality seriously according to
Rely in welder's level, limits the research and development and application of deep & ultra-deep well coiled tubing operation device.
Pipeline flash butt welding technology has many advantages, such as high degree of automation, without solder and welding quality stable, in oil gas
Delivery pipe connection area has broad application prospects, and is widely applied in external especially Russia and Ukraine.State
The interior research ability ground zero about pipe line steel flash butt welding technology, and continuous pipe flash butt welding technical research is even more to be rarely reported.
Research in terms of therefore, it is necessary to carry out continuous pipe flash butt welding.And flash butt welding method is used to carry out joint connection in site to continuous pipe
When, since tube wall is grounded, it is unable to complete welding, seriously restricts flash butt welding technology answering at continuous pipe oil field operation scene
With needing to develop a kind of continuous pipe flash butt welding method that can be used for produced on-site.
Summary of the invention
In order to overcome the above-mentioned deficiencies of the prior art, it can be used for the continuous of produced on-site the object of the present invention is to provide a kind of
Pipe flash butt welding method, the reparation problem after connecting and damage based on the pipe encountered in continuous tube field operation-pipe, in pipe
Road connection area has broad application prospects.This method is applicable not only to pipe-pipe connection of christmas field continuous tube field
With the reparation after damage, applies also for oil and gas pipeline and connect and repair with the pipe-pipe at underground water pipeline scene.
To achieve the goals above, the technical solution adopted by the present invention is that:
A kind of continuous pipe flash butt welding method can be used for produced on-site, including electrode holder, electrode holder connect lateral cylinder and indulge
To cylinder, lateral cylinder and longitudinal cylinder are controlled by control cabinet, and electrode holder is by electrical system power transmission, the continuous pipe flash of light pair
Soldering method the following steps are included:
1) equipment is opened in control cabinet, continuous pipe is put into electrode holder, and is installed steady；
2) electrode holder button, longitudinal cylinder starting are pressed in control cabinet, electrode holder clamps；
3) start electrical system, give electrode holder power transmission, intermediate electrode holder is anode, and the electrode holder on both sides is cathode；
4) lateral cylinder works, and the electrode holder on both sides is sent into identical speed to centre, to the sample in the electrode holder of both sides
When with sample contacts in target folder, flash of light processes occur for two connectors, and after a distance of glistening, two end electrodes folder is reversed
Mobile, after a distance to be removed, two end electrodes are fed with certain speed to middle sample entrainment of sample, in two connectors
There is appropriate overlap to generate, flash butt welding process is completed；
5) under the action of the cylinder, electrode holder unclamps, and removes sample；
The electrical system provides power to continuous pipe flash butt welding process；
The control cabinet controls continuous pipe flash butt welding process；
The lateral cylinder and longitudinal cylinder provides thrust to continuous pipe flash butt welding process；
The electrode holder provides clamping and electric action to continuous pipe flash butt welding process.
The beneficial effects of the present invention are:
This method solve, since tube wall is grounded, the problem of can not welding, can be used for continuous pipe field when continuous pipe field work
Joint connection in site, speed of welding is fast, and joint performance is good, and quality is reliable and stable.
