Description
Technical field
The utility model belongs to the equipment or the device technique field of recover petroleum or the external application of natural gas oil well, is specifically related to the adjustable height workbench that a kind of coiled tubing oil field work that is used for that the coiled tubing of bending is carried out the preceding preparation of weldering of butt welding and implements to weld is automatically used.
Background technology
(Coiled Tubing CT) is the endless tubing that is welded by butt welding or inclined weld technology at the flexible pipe more than hundred meters by plurality of sections length to coiled tubing, and length can reach hundreds of rice to several kms, is also referred to as coiled tubing, coiled pipe or coil pipe.With respect to being threaded for the conventional oil pipe of going into the well, coiled tubing is wound on the reel and directly goes into the well after stretching.The coiled tubing commanding apparatus is called coil pipe working rig or coild tubing unit (Coiled Tubing Unit, CTU), be that the coiled tubing that a kind of mobile hydraulic drives removes transporting equipment, it is lowered to and trips out coiled tubing in production tube or sleeve pipe when the coiled tubing operation, and the coiled tubing that trips out is wound on the reel so that transportation.The coiled tubing technology is mainly used in well workover, well logging and bores completion practice, and the typical process that is used for workover treatment has squeezing off, salvaging, drifting reaming hole, sand-flushing, scale removal, release to lure stream, annotates the nitrogen well testing, acidizing treatment (pickling, fixed point are annotated sour), oil pipe anti-corrosive processing operation and coiled tubing separate stratum fracfturing etc. do not stop production; The typical process that is used to bore completion has old well heavily to bore intensification, slim-hole horizontal drilling, under balance pressure drilling, gaslift completion, cross oil pipe sand control treatment etc.; Coiled tubing can also be used for cleaning, cementing and underreamer, salvaging, sand control, well logging and the perforation of sand and impurity in addition, also can be used as the speed tubing string, implement to stride across the cleaning of completion interval of well section and local acidifying, kill-job, flushing sand plug, underbalance perforating, well testing, high angle hole electrical measurement, salvaging and use as production tube at peupendicular hole and high angle hole; In addition, coiled tubing is used as flow line and gathering line also has bigger application potential, and especially in recent years, external application aspect coiled tubing drilling has obtained comprehensive development.
The coiled tubing operation technique is compared with the routine work technology, and have following advantage and characteristics: one, operating cost is low, because CTU equipment is few, resettlement is installed and well in operation time weak point, and rountrip speed is fast, and workload is little, can directly reduce cost, reduce expenses 25%～40%; Two, increase oil well output, coiled tubing operation technique or heavily bore or sidetrack horizontal well by the old well of oil pipe, can make does not have the old well of economic benefit to increase output originally; Three, protection oil reservoir, job safety can be carried out not open flow, put pressure for some responsive stratum, and band is pressed and worked continuously, and prevents formation contaminant, and is safe and reliable; Four, in high-inclination directional well, carry out as electrical measurement and steel wire rope operation, or the sand-flushing operation in net horizontal section, the advantage of convenient working had; Five, because the CTU floor space is little, be particularly suitable for restricted offshore platform drilling well of surface condition and through-tubing drilling operation, not only shorten duty cycle, and increase output, reduce cost.
But coiled tubing is occurred depression owing to a variety of causes can cause oil pipe break or oil pipe section by improper extruding in the process of going into the well, or certain section will be welded the part and the down-hole part of fracture when by improper corrosion the coiled tubing quality seriously being descended need to block; Oil well reaches when coiled tubing length wants continued access new to coil coiled tubing inadequately under several kms deeply in addition, the coiled tubing welding lengthening that length is not enough continues to be fed into the down-hole, because coiled tubing one end is wrapped on the spool, flexural deformation is very big, the other end is pulled out in well by force, distortion is complicated, the linearity of coiled tubing and circularity can be subjected to very big influence, therefore must correct its shape before the coiled tubing weldering, could guarantee welding quality, also not have a kind of basic platform that can be used in the preceding preparation of the on-the-spot solution of oilfield coiled tubing butt welding and implement to weld automatically at present.
