Novel casing collar locator for coiled tubing

Abstract

The invention relates to the technical field of novel casing collars, and discloses a novel casing collar locator for coiled tubing. The locator comprises a shell, a screw rod is arranged in the shell, a mounting groove is formed in the shell, a rubber plate is arranged in the mounting groove, and a sound transmission groove is formed in the shell. According to the novel casing collar locator for the coiled tubing, a push rod drives an arc-shaped plate to move, so that the effect of locating a casing collar is achieved; a copper rod is matched with an N pole and an S pole, so that the effect of automatically stopping after the casing collar is fixed is achieved; the sliding plate is in contact with the feeler lever, so that the effect of automatically detecting whether the oil pipe is broken or not is achieved; and a bell is continuously hit through a hitting rod, so that a certain prompt can be given to a worker, and the situation that the worker forgets to overhaul due to negligence is avoided.

Description

technical field [0001] The invention relates to the technical field of novel casing collars, in particular to a novel casing collar positioner for coiled tubing. Background technique [0002] The tubing collar plays the role of connecting the two ends of the tubing downhole to form a continuous tubing string and drain the downhole fluid, and the casing collar positioner plays a very important role in it. [0003] The traditional casing collar locator for coiled tubing often adopts the collar locator based on the principle of electromagnetic induction, but due to the complex underground conditions, there may be certain errors in the use of the traditional locator, and if the positioning process After the middle casing collar deviates, the oil inside the pipeline may leak, resulting in a waste of resources. In addition, the traditional collar positioner needs to be checked and repaired regularly by the staff during use to prevent leakage. In the case of leakage, for the staff...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a novel casing collar positioner for coiled tubing, which can automatically position the tubing, automatically stop running after successful positioning, can automatically detect whether the tubing leaks, and can automatically detect whether the tubing leaks. It has the advantages of giving certain reminders to the staff when using the traditional positioner, which solves the problem that there may be certain errors in the use of the traditional positioner, and if the casing collar is shifted during the positioning process, the oil inside the pipeline may leak , resulting in a waste of resources, and the traditional coupling positioner requires staff to regularly overhaul it during use to prevent leakage. In this way, for the staff, each part needs to be overhauled, so A lot of time and energy will be wasted, and work efficiency will also be reduced
