Description
Technical Field
The utility model belongs to a connecting device for online detection of a coiled tubing.
Background
When the continuous oil pipe is subjected to online detection operation at present, a detector and the continuous oil pipe are connected and fixed without a device, so that the detector shakes up and down and left and right to seriously influence the detection sensitivity. The patent number CN201620079600 provides a coiled tubing test data acquisition system, which provides data support for coiled tubing drilling and grinding, salvaging and other operation fields by accurately detecting the stress condition of coiled tubing in the test processes of coiled tubing drilling and grinding, salvaging and the like. The mode of collecting data through the electrically connected sensor group has the defect that the problem of inaccurate collecting result of the sensor collecting box exists due to vibration, up-down left-right shaking and the like of the coiled tubing during operation in the field operation process of the coiled tubing. For another example, CN107632061A discloses a method for marking defects in online coiled tubing inspection, which comprises passing coiled tubing through a defect inspection device installed on a roller tube arranger at a traveling speed of 0.5 m/s, and inspecting the defects on the coiled tubing one by one, wherein the defects include surface defects, wall thickness deviations, ovality deviations, and the like. The patent only mentions a coiled tubing on-line detection defect marking method, a connection method between the detector and the coiled tubing in the defect detection process is not described in detail, and similarly, in the defect detection process, the detector and a counting device installed on the coiled tubing can shake up and down, left and right in the operation, and the detection sensitivity is influenced.
