Problems solved by technology

During the operation, the wall thickness and ellipticity of the coiled tubing will change due to fatigue damage, acid corrosion, sulfide cracking, pressure or tension overload, external mechanical damage and wear, and may also cause crack defects in the tubing
This reduces the useful life of the coiled tubing and increases operating costs for the coiled tubing service company

Embodiment Construction

[0027] Such as figure 1 As shown, an integrated coiled tubing defect detection device includes two detection units, the upper half detection unit and the lower half detection unit. The two detection units are connected by two locking buckles. After the two detection units are assembled with each other, a channel through which the oil supply pipe passes is created between the two. In the channel, there are magnetic generation devices and magnetic flux leakage arranged on the two detection units. Detection probe, ellipticity detection probe and guide device, the detection unit is connected with a measuring arm assembly that guides the two detection units to move along the oil pipe, and the detection unit is also connected with a connecting rod assembly for connecting peripheral equipment.

[0028] Such as figure 1 As shown, the integrated coiled tubing defect detection device of the present invention adopts a clamshell design, and the overall structure is composed of an upper h...

Abstract

The invention provides an integrated coiled tubing defect detection device. The coiled tubing defect detection device comprises an upper half detection unit and a lower half detection unit, and a passage for coiled tubing to pass through is formed between the two detection units after the two detection units are matched and assembled with each other, and internally provided with a magnetism generating device, a magnetism leakage detection probe, an ellipticity detection probe and a guide device which are arranged on the two detection units; a measuring arm assembly kit for guiding the two detection units in moving along the coiled tubing is connected to the outsides of the detection units. The device can achieve real-time and precise detection of the wall thickness, outer diameter, ovalityand various physical defects such as corrosion, cracks, mechanical damage and pitting corrosion of coiled tubing columns.

Description

technical field [0001] The invention relates to the fields of petroleum equipment manufacturing and non-destructive testing, in particular to an integrated coiled tubing defect testing device. Background technique [0002] Coiled tubing is welded by a number of flexible pipe sections with a length of more than 100 meters through butt welding or skew welding, and the length is generally several hundred meters to several thousand meters. Each pipe column is a welded pipe formed by steel strip and welded by resistance straight seam. In recent years, coiled tubing has been used more and more widely in oilfields, such as gas lift, acidizing, drilling and grinding, downhole tool fishing, well washing, perforating, etc. During the operation, the wall thickness and ellipticity of the coiled tubing will change due to fatigue damage, acid corrosion, sulfide cracking, pressure or tension overload, external mechanical damage and wear, and may also cause crack defects in the tubing . ...
