Description

Drilling device mud processing system based on clean mud distributing flume

Technical Field

The invention relates to a clean slurry distribution groove structure design for a drilling device slurry treatment system, which can meet the design requirements of functions related to slurry treatment and discharge in the drilling device slurry treatment system.

Background

For the mud after the well head of the drilling device reflows, the whole processing flow is an important link for the drilling operation, generally, the mud after the well head reflows is distributed to each vibrating screen through a mud distributor, and the mud after the vibrating screen processing has solid waste mud (namely rock debris) and reusable clean mud. The waste mud (namely the rock debris) is large mud screened out by the vibrating screen, is discharged from the stern of the vibrating screen, and the clean mud filtered by the screen flows to the bottom of the vibrating screen and then flows out from outlets at two sides of the bottom of the vibrating screen. The waste mud (namely the rock debris) can be directly discharged to the sea or collected after being treated, and the clean mud flowing out of the bottom of the vibrating screen flows to each mud treatment tank (a sand basin, a degassing tank, a sand removal tank and a mud removal tank) for treatment and then flows back to the ship body mud tank for reuse.

How the mud flowing out of the two sides of the vibrating screen flows to each mud treatment pool is a key link of the design problem. Most drilling installations are equipped with four or five vibrating screens and a mud cleaner (the mud cleaner is composed of a vibrating screen, a sand remover and a mud remover integrated skid block, wherein the sand remover and the mud remover are arranged above the vibrating screen), and mud returned from the wellhead can be further processed by the sand remover and the mud remover on the upper part of the mud cleaner according to the components of the mud, or the mud cleaner can not be needed. The mud flowing out of the vibrating screen needs to be distributed to different mud treatment pools according to specific components of the mud, one traditional design scheme is that a plurality of vibrating screens and cleaners are designed into an integral prying block, mud flow outlets on two sides of each vibrating screen are connected together, and the mud flow outlets are supplied by equipment manufacturers. The design has the problems that the supply cost is increased, the size of the whole prying block and the size and the position of the upper slurry outlet are not necessarily matched with those of the slurry treatment pool, the position and the size of relevant parts on the prying block need to be adjusted, and the trend distribution of slurry cannot be observed specifically.
