A drilling platform mud recovery and drill pipe thread cleaning and oiling device

Abstract

The invention relates to the technical field of drill pipe thread cleaning and oiling, and relates to an automatic device for recovering drilling mud, thread cleaning and oiling. With the development concept of green and environmental protection deeply rooted in the hearts of the people, higher requirements are put forward for the recovery and treatment of mud in oil drilling. Mud and sand residues are easy to appear on the thread of the drill pipe joint. If it is not cleaned and oiled, the mud and sand are easy to scratch the drill pipe thread and cause downhole accidents. The present invention has a reasonable and compact structure and is easy to use. It is equipped with a planar movement positioning mechanism (01), a working lifting mechanism (02), a tapping thread cleaning and oiling mechanism (03), a female thread cleaning mechanism (04), and a drilling fluid receiving mechanism (05). ) to realize drilling platform mud recovery, automatic thread cleaning and oiling, which can effectively solve the problem that the mud in the drill string is difficult to be recovered automatically and pollute the table, so that the mud does not fall to the ground. At the same time, the drilling efficiency is improved, downhole drill pipe accidents are reduced, and labor intensity is reduced.

Description

technical field [0001] The invention relates to the technical field of mud recovery, drill pipe thread cleaning and oiling, and relates to a drilling platform mud recovery, drill pipe thread cleaning and oiling device. Background technique [0002] In the process of oil and gas drilling and production, tripping operations must be performed many times due to various reasons, and the number of drill pipes connected in the drilling operation generally ranges from 200 to 1,000. The number of times of recovery and recovery is very large, and the workload of recovery of mud and cleaning and oiling of drill pipe threads also increases. The traditional treatment method is: wrap the drill pipe with a woven bag, and fix it at the position in front of the front tightening, relying on the mud in a part of the drill string of the woven bag. But the effect is not very good, the woven bag is easy to loosen, or is dragged back to the inside of the front tightening device to affect the cons...
