The coiled tubing (CT for short) is widely applied to the fields of exploration and development of oil and gas wells such as well workover, well logging, well drilling and the like. The coiled tubing has superior performance and can be operated under pressure, has absolute advantages compared with the common tubing, and is a novel petroleum tubing. At present, the coiled tubing technology is mature, and the coiled tubing can be used as a conveying pipeline instead of a conventional oil tube and can also be used for oil tube perforation. Coiled tubing is coiled on the drum under non-operating condition, can pass through repeated bending when the borehole operation, and the body is in elastic deformation state. In addition, the pipe body is easy to rub when the coiled tubing is operated underground, and the coiled tubing can cause the section of the coiled tubing to be oval. The ovalization of the oil pipe can reduce the anti-extrusion capability of the oil pipe and shorten the service life. After the ovality of the in-service coiled tubing changes, serious consequences are easily caused, and the safety operation is greatly threatened.
In order to ensure safe field operation, the ovality of the coiled tubing needs to be detected accurately in time, the deformation of the coiled tubing is analyzed, damaged and bent parts are repaired in time, and the service life of the coiled tubing can be prolonged effectively. The eddy current displacement sensor is a non-contact sensor based on eddy current effect, and can measure process quantity and state quantity. The detection of the ovality of the continuous oil pipe is to measure the diameters of the same section of the continuous oil pipe in all directions and compare the maximum value and the minimum value of the measurement result to obtain the ovality. Most ovality detection device is the integral type at present, because the great sensor probe that same cross-section was placed when detecting minor diameter coiled tubing of test probe is limited, the diameter of same cross-section all directions of unable accurate measurement causes detection error, influences detection effect and coiled tubing's life.
