Abstract
The utility model relates to welding seam metal material coiled tubing for the downhole operation, which is formed by welding continuous long tube bodies as required. The tube bodies are formed by bending boards and can be processed into different section shapes as required; and the boards are welded to form a closed space above the cross section, so that the boards form a coiled tubing with required length through the connection of welding seams. For meeting the requirements for electromotive force and signal transmission, boards can be bent into a shape provided with a grooved cross section, and power cables and signal wires can be embedded in the grooves; and for meeting the requirement of a downhole on double channels, the boards can be bent into an S shape and are welded to form the coiled tubing with double channels.
Description
Affiliated technical field
The utility model relates to the underground work field, and particularly a kind of drilling and repairing well, well logging, pressure break, downhole testing use the weld metal continuous-tube.
Background technology
The continuous-tube of seamless steel exists the problems such as transmission that manufacturing is difficult, size is single, can not carry out electric power and signal.
Development along with science and technology, there is the weld metal continuous-tube can reach the technical indicator that seamless pipe has, also have easily manufactured, can be processed into the circular or needed round complicated shape that is different from, to reach the higher requirement of underground work, also be easy to realize the transmission of electric power and signal.
Summary of the invention
In order to overcome the deficiencies in the prior art part, the utility model provides that a kind of underground work uses the weld metal continuous-tube.
The technical scheme that its technical problem that solves the utility model adopts is: have the weld metal continuous-tube to comprise body 1 and weld seam 2.It is characterized in that: body 1 is to be bent by sheet material to form, and can be processed into as required different shapes; Weld seam 2 connects into sheet material the continuous-tube of Len req.
For satisfying the needs of realizing power and signal transmission, can be bent into reeded shape to sheet material, in groove, can inlay power cable and holding wire, the quantity of groove is 2 to 5.
For satisfying the down-hole to twin-channel requirement, can be bent into the S shape to sheet material, and be welded into twin-channel continuous-tube.
For satisfying the needs of special process, there is weld metal material continuous-tube can be processed into double-deck structure.Body 1 is tubular, and section has increased inner tube 4 within it, and has increased dividing plate 3 between two pipes.Dividing plate 4 can link with inner tube 4, also can link with the continuous-tube 1 of outside.The quantity of dividing plate can be 2-6.Power cable and signal transmssion line can be placed between the inner and outer pipes.
The beneficial effects of the utility model are, compare with the seamless steel continuous-tube of present use, this utility model has avoided making the problems such as inconvenient, that model is few, use cost is high, can be processed into the circular or needed round complicated shape that is different from, to reach the higher requirement of underground work, also be easy to realize the transmission of electric power and signal.
