Problems solved by technology

However, for the collected defect magnetic flux leakage signal, it is still necessary to manually analyze the filtered waveform diagram to determine whether there is a defect and the approximate location of the defect. The location of the defect cannot be accurately located, which affects the safety of the oil pipeline operation.

Abstract

The invention discloses an installation method of a coiled tubing defect spray marking system, which belongs to the technical field of tubing detection, and is characterized in that it comprises the following steps: S1, installing the coiled tubing through the marking positioning device, and setting the roller encoder in the continuous On the magnetic flux leakage detection unit of the tubing magnetic flux leakage detection device; S2. Connect the marking positioning device with the electrical control box, connect the coiled tubing magnetic flux leakage detection device with the signal processing box, and the signal processing box is connected with the electrical control box respectively. The control box is connected to the computer; S3. Finally, insert the debugged paint spray gun into the spray gun ferrule, and align the nozzle of the paint spray gun with the wall of the coiled tubing. The whole installation process of the present invention is convenient and fast, and can realize the stable connection between the magnetic flux leakage detection device of the coiled tubing and the marking positioning device, and realize the precise marking positioning of defects, which not only ensures the safety of the coiled tubing operation, but also reduces the operating cost.

Description

technical field [0001] The invention relates to the technical field of oil pipe detection, in particular to an installation method of a coiled oil pipe defect spraying system. Background technique [0002] With the rapid development of unconventional oil and gas, unconventional operations are increasing year by year. Unconventional oil and gas mainly include tight sandstone oil and gas reservoirs, tight carbonate rock oil and gas reservoirs, shale oil and gas reservoirs and coalbed methane. Coiled tubing operations, which have a series of advantages of short operation period, can be lifted and lowered under pressure, safety and high efficiency, cost reduction and reservoir damage reduction, are more and more favored by various oil companies. Coiled tubing has been widely used in sand washing, well washing, salvage, gas lift drainage, drilling and grinding bridge plugs, perforation, logging of highly deviated wells and horizontal wells, acidizing and fracturing of oil and wa...
