Problems solved by technology

In the process of lifting the drill, it is necessary to manually clean the sludge on the surface of the drill pipe with a hand-held mud scraper. Usually, the mud scraping work of the drill pipe is a simple but highly repetitive manual operation. It is used for drilling thousands of meters deep. The number of drill pipes is huge, and manual mud scraping for a long time is a very inefficient work

Embodiment Construction

[0016] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0017] Such as figure 1 figure 2 Shown: a vertical purely mechanical drill pipe mud scraper, including two powerful magnet suction cups 7 adsorbed on the drill floor next to the wellhead. There are uprights 5, and the uprights 5 are arranged horizontally with each other, and the top of the uprights 5 is provided with a working grip 8, and the working grip 8 is provided with a semicircular left casing 1, and one end of the left casing 1 is connected with a semicircular Shaped right housing 2, the other end is provided with a locking mechanism 4 that can fasten the left housing 1 and the right housing 2, and the left housing 1 and the right housing 2 are provided with ring-shaped rubber mud scrapers 3. The left casing 1 and the right casing 2 are buckled together to form a ring structure.

[0018] The inside of the left housing 1 and the right housing 2 are...

Abstract

The invention discloses an upright pure mechanical drilling rod mud scrapping device. The device comprises two powerful magnet suction plates, the powerful magnet suction plates are provided with upright rods, working grippers are arranged on the tops of the upright rods, semicircular left housings are arranged on the working grippers, semicircular right housings are connected with the ends of theleft housings, locking pin mechanisms which can buckle the left housings with the right housings are arranged at the other ends, and circular rubber mud scrapping pieces are arranged in the left andright housings. When the device is used, the two powerful magnet suction plates adhere to a steel drilling well platform, the locking pin mechanisms are switched on to separate the left and right housings, the grippers on the edges of the left housings are held by hands, the left housings are moved to allow the rubber mud scrapping pieces installed in the left housings to be completely in contactwith the outer walls of drilling rods before the right housing are gathered up, the locking mechanisms are used, and after the upper portions of the drilling rods are in positions, the locking pin mechanisms are switched on again to draw back the left housings to wait for the next repeated movement. The device has the advantages of being time saving, strength saving, and capable of improving the safety of the drilling platform and reducing the labor intensity of drilling well workers.

Description

technical field [0001] The invention relates to the technical field of petroleum drill pipes, in particular to a vertical purely mechanical drill pipe mud scraper. Background technique [0002] At present, the drill pipe is the main working component of the drilling operation. After each downhole operation, a large amount of drilling mud and cuttings and other sludge particles will be adhered to the surface. In the process of lifting the drill, it is necessary to manually clean the sludge on the surface of the drill pipe with a hand-held scraper rope. Usually, the mud scraping work of the drill pipe is a simple but highly repetitive manual operation. It is used for drilling thousands of meters deep. The number of drill pipes is huge, and manual mud scraping for a long time is a very inefficient work. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies in the prior art, the object of the present invention is to provide a vertical purely...
