Adjustable drilling tool mud-scraping device

Abstract

The invention relates to the field of oil field drilling, in particular to an adjustable drilling tool mud-scraping device. The adjustable drilling tool mud-scraping device is simple in structure, convenient to move horizontally, and easy to install. The adjustable drilling tool mud-scraping device comprises a hoisting device and a scraper assembly, wherein the hoisting device comprises a fixing frame and a pair of parallelly-arranged moving frames, the pair of moving frames are separately and slidably connected to the fixing frame, and the moving frames are connected to the scraper assembly by a hanging assembly; the scraper assembly includes a U-shaped frame and a pair of scraping assemblies, and a U-shaped opening of the U-shaped frame is oriented in the same direction as the moving direction of the moving frames; the pair of scraping assemblies are disposed opposite to each other on the inner ends of two sides of the U-shaped frame and are arranged up and down; and the pair of scraping assemblies comprises inflatable scraping blades, steel rings, a pair of swinging cylinders, rotating shafts, a pair of fixing seats, a pair of swinging rods, and an air source. Flexible contact is achieved, the adaptability is wide, and the compactness of the mud-scraping device with a drill pipe is adjusted through regulating the air pressure of the inflatable scraping blades to improve thescraping effect.

Description

technical field [0001] The invention relates to the field of oil field drilling, in particular to an adjustable mud scraping device for drilling tools. Background technique [0002] During drilling operations in oil fields, mud adheres to the drill pipe, which affects the work of the drill pipe. At the same time, if the mud on the drill pipe is taken out to the drilling platform, it will seriously affect the working environment; therefore, it is very necessary to remove the drill pipe. Mud on the pole. [0003] The announcement number authorized by the State Intellectual Property Office on July 12, 2006 is CN2795439Y, and the patent title is "a kind of mud scraper". It is equipped with two sets of upper and lower mud scraper devices in the open barrel, which can effectively and automatically scrape the drill pipe The mud on the surface can reduce the labor intensity of oil workers; however, there are the following problems in the working process: [0004] 1) The positions ...

AI Technical Summary

Problems solved by technology

[0004] 1) The positions of the drill pipe and the mud scraper are relatively fixed, which is inconvenient to move the mud scraper; 2) It is not easy to replace the drill pipe, and the operation is complicated; 3) The assembly of the drill pipe and the mud scraper takes a long time, reducing the work efficiency
