Description

Intelligent trolley for cleaning drill floor

Technical Field

The utility model relates to a clean field of rig floor face particularly, relates to an intelligent vehicle for rig floor face cleans.

Background

On the drilling operation site, whether the drilling platform surface is clean is a key factor influencing the working efficiency and personal safety of well head operators. According to the field practical experience, common mud spraying conditions and reasons are summarized: 1. and during the drilling operation, slurry is remained in the drill rod, and when the upright column is dismounted, pressure difference exists and can be sprayed out from the lower single joint in the upright column. While there is a heavy mud fill on site and a blowout preventer is used to prevent mud spray, the heavy mud eventually fails as the pull-out length and pull-out time increase. The manual use of the blowout preventer can cause two results due to inaccurate judgment: a. the stand column without mud is closed, and the drilling time efficiency is reduced. b. The column with the slurry is not closed, and the slurry is sprayed. 2. The mud returns and is sprayed out of the drill pipe, and the mud has uneven density or is collapsed due to the fact that drilling fluid is not filled. 3. And (3) manual misoperation is carried out, and the top drive inner blowout preventer is not closed when the upright post is dismounted.

If the table top is cleaned manually, the following hazards are caused: 1. the sprayed mud falls on the drilling platform surface, so that the drilling platform becomes sticky and smooth and is difficult to walk, the working failure is reduced, and the escape risk of well head operators after accidents is increased. 2. The on-site cleaning mainly uses diesel oil and towels, and people squat for a long time on a drill floor to clean, so that body blood cannot be well circulated. Diesel oil and towels belong to consumable materials, and the drilling operation cost is increased.
