Description
Technical field
The present invention relates to petroleum drilling technology field, more particularly to a kind of centrifuge apparatus for being used to reclaim barite and its
Application method.
Background technology
In Process of Oil Well Drilling, using the circulation of drilling fluid come cutting carring, holding pressure, in the cyclic process of mud
In order to ensure being normally carried out, it is necessary to add bentonite, barite, organic salt, Iron Ore Powder etc. in mud again of drilling well.Conventional place
Managing the Fang Fang of weighted drilling fluid includes two kinds：By diluting whole drilling fluids, while addition a large amount of new weighting materials and chemistry
Agent；UNICOM's weighting material and rock drilling cuttings are separated abandon together.The method that wherein the former uses, which can not be removed effectively, to be blended in
Useless solid phase in drilling fluid；The method that the latter uses causes the serious waste of barite.For the latter use method and
Speech, the mud routed up from well head reenters circulation after treatment, and mud is when by centrifuge, and what is disposed is not only
Useless solid matter, still disposes the utilities such as a big chunk barite, Iron Ore Powder.In follow-up flow
Still these useful materials are rejoined, the need for meeting drilling well.
The mud conditioning flow of the existing centrifuge generally used is typically that mud enters centrifuge by inlet, by from
After the processing of scheming, liquid is further handled via liquid outlet into next centrifuge, and solid matter is discharged with sand removing hole.By
The solid matter of centrifuge processing is big in shape, viscosity, is not easily recycled and handles, be just thrown away under normal circumstances, causes people
A large amount of wastes of the important substance such as the waste of power resource and barite.
Up to hundreds of tons of the consumption of barite when a well, especially deep-well, ultradeep well is often bored in oil field, and barite price
Hundreds of members per ton, in order to be able to preferably reduction drilling cost, therefore study a kind of new centrifuge apparatus for reclaiming weight crystalline substance
Stone is to environmental protection and reduces cost etc. with long-range Research Significance.
