Description

Technical Field

[0001] The utility model relates to the technical field of joint plug - and - unplug inspection, in particular to a tubing joint plug - and - unplug inspection device. Background Technique

[0002] The tubing is a pipeline that transports crude oil and natural gas from the oil and gas layer to the surface after drilling is completed, and it is used to withstand the pressure generated during the exploitation process. After the tubing is produced, it is usually necessary to conduct plug - and - unplug inspection on the tubing to determine whether the tubing quality is qualified and ensure the production quality. However, the traditional tubing plug - and - unplug inspection is usually carried out by manually holding and plugging / unplugging, which is not only laborious but also has extremely low efficiency.

[0003] For example, a tubing quick plug - and - unplug device applicable to industrial vehicles disclosed in the authorized announcement number CN211398919U. The utility model is achieved through the following technical solutions: A tubing quick plug - and - unplug device applicable to industrial vehicles includes a tubing group. Each tubing group includes a tubing, and each tubing group includes an inlet tubing and an outlet tubing; it also includes a connection block. The connection block includes an oil - passing channel for the tubing to be inserted. The oil - passing channel includes an inlet oil channel connected to the inlet tubing, an outlet oil channel connected to the outlet tubing, and a through - channel connecting the inlet oil channel and the outlet oil channel. The purpose of the utility model is to provide a tubing quick plug - and - unplug device applicable to industrial vehicles, which has good fixing effect on the tubing, is beneficial to the orderly position of the tubing during the movement of the gantry, and protects the tubing. However, it is difficult for this utility model to achieve the effect of repeated mechanical plug - and - unplug inspection of the tubing, and its role in the quality inspection operation during tubing production is relatively small. Therefore, we propose a tubing joint plug - and - unplug inspection device, which solves the problem of mechanical repeated plug - and - unplug inspection during tubing production, improves the tubing detection efficiency and production efficiency, and saves labor.
