Description

Technical Field

[0001] The utility model relates to the technical field of tubing cleaning in the fields of petroleum engineering and drilling, and particularly relates to a full-automatic crawler-type oil and casing thread cleaning machine. Background Art

[0002] A tubing is a pipeline for transporting crude oil and natural gas from an oil and gas layer to the surface after drilling is completed. Due to operating environment limitations, all parts of the tubing or casing need to be stain-resistant, corrosion-resistant, and pressure-resistant. Once a tubing leakage accident occurs, the entire tubing will be scrapped and needs to be redrawn and reinstalled, which will greatly waste manpower and material resources. Generally, each tubing is more than ten meters to dozens of meters long, and the two ends of a tubing are respectively a male joint and a female joint. The screwing thread at the male joint part is located outside the tubing, and the screwing thread at the female joint part is located inside the tubing. When screwing two tubings together, the male joint of one tubing is screwed into the female joint of the other tubing to connect the two tubings together. The joint part not only requires high connection strength but also good sealing performance. However, when connecting two tubings, collisions inevitably occur between the male joint and the female joint, which will cause scars at the connection part. At the same time, substances such as carbon dioxide and hydrogen sulfide inside the oil and gas field will corrode the tubing, especially at the connection part with scars, and the corrosion phenomenon is more serious, resulting in tubing leakage and failure. Therefore, before connecting two tubings at the construction site, it is generally necessary to clean the tubings first, especially the male and female joints of the tubings.

[0003] At present, although there are tubing cleaning machines that replace manual cleaning, such as the Chinese utility model patent with the application publication number CN106694487A and the title of tubing cleaning machine. However, oil fields and gas fields are often located in remote and harsh geographical environments, and the tubing cleaning machines on the market are inconvenient to move and operate in environments such as deserts and gobi. Therefore, there is an urgent need to develop a tubing cleaning machine with strong environmental adaptability. Summary of the Utility Model
