Abstract

The invention provides a tubing coupling detection device and a reducing pipe column detection device. The tubing coupling detection device comprises a static platform, a movable platform and a detector, wherein the static platform can be fixed to a wellhead and is provided with a first through hole for a pipe column moving axially to penetrate through; the movable platform is movably arranged on the static platform, is provided with a second through hole for the pipe column to penetrate through and can move relative to the static platform along a first plane parallel to the radial plane of the pipe column; and the detector is movably mounted on the movable platform and makes contact with the outer wall of the pipe column, the detector and the movable platform can move along the first plane along with the pipe column and keep relatively static when the pipe column deviates radially, and a tubing coupling of the pipe column enables the detector to move relative to the movable platform and trigger the detector when passing through the detector. The tubing coupling detection device is high in detection accuracy and can meet the requirement for automation of operation under pressure and workover treatment.

Description

technical field [0001] The invention relates to the technical field of oil field hot-press operation, in particular to a detection device for an oil pipe coupling and a detection device for a variable-diameter pipe string. Background technique [0002] With the continuous promotion of snubbing technology, low-pressure snubbing technology has gradually matured, and has changed from special operations to routine operations, in which lifting and lowering pipe strings is the most important operation process, which is highly repetitive and takes up man-hours. , The underpressure operation is always a construction operation under high pressure conditions, and the spirit of the operator is always in a state of high tension. Therefore, in order to reduce the labor intensity of the operator, the demand for automatic underpressure operation has been put forward. The same situation also exists in conventional workover operations, and with the aging of operators, the lack of timely repl...
