Suspended movable drill rod mud scraping device

Abstract

The invention discloses a suspended movable drill rod mud scraping device, which comprises a shell, and is characterized in that: the lower part of the shell is provided with an insertion opening for inserting into a drilling disc bushing; a suspension seat is arranged in the shell; the shell and the suspension seat are meshed by two bodies and are locked via a latch; a fixing square sleeve is fixedly arranged in the suspension seat along a circumferential direction; an inner sliding sleeve capable of sliding in a reciprocating way is arranged in the fixing square sleeve; one end of the innersliding sleeve corresponding to the center of the suspension seat is clamped with a special shaped rubber block; a movable top plate and a pressure spring are arranged in the inner sliding sleeve respectively; and a lead screw nut transmission component for adjusting the pressure of the pressure spring is arranged between each movable top plate and the suspension seat. The suspended movable drillrod mud scraping device has the advantages that: the mud on a drill rod and a box coupling of the drill rod can be scraped completely; the mud is prevented from splashing down on a drilling platform to pollute the environment and influence the operation of the worker; the potential safety hazard is eliminated, the labor intensity is low, and the scraping device is convenient to assemble and disassemble, and the drilling operation is not influenced.

Description

technical field [0001] The invention relates to a cleaning device for scraping mud on drill pipes during drilling in an oil field, in particular to a suspended mobile drill pipe mud scraper. Background technique [0002] In the process of oil field drilling, it is often necessary to move the drilling tool and pull out the drill. Especially in the process of pulling out the drill pipe, the mud attached to the outer surface of the drill pipe often splashes on the drill floor and the workers, which is not only not conducive to the work of the workers, pollutes the environment, but also brings to safety hazards. In order to avoid mud splashing when pulling out the drill, in the traditional drilling construction operation, two drilling workers squat down and hold two semi-circular iron sheets or use a rope to scrape off the mud attached to the drill pipe. This scraping method works The strength is high, the mud on the drill pipe cannot be scraped clean, and part of the mud will ...

AI Technical Summary

Problems solved by technology

Since the mud scraper is a closed ring, the elastic change of its diameter is small. Using the above-mentioned drill pipe mud scraper tool cannot effectively scrape the mud on the entire drill pipe. Cause the drilling cannot be completed smoothly
