Embodiment Construction

[0024] The separator according to the invention is a separator suitable for removing solids from liquids and in particular from drilling fluids. The separator includes a tube settler through which drilling fluid can flow. The separator also includes a transportable solids collection container. The tube settler and the solids collection vessel are separate or separable and arranged such that the solids collection vessel is located below the tube settler so that it can receive the solids separated by the tube settler.

[0025] The solids collection container can be transported independently of the tube settler. Thus, a standard waste disposal hopper can be used as both a particle collection container and a particle transport container in an efficient manner by using standard on-board hopper processing equipment.

[0026] Preferably, the separator further comprises a knock-out tank. The separator tank referred to here is the primary separation vessel used to remove coarse soli...

Abstract

The invention provides a separator for the removal of solids from a drilling liquid, the separator comprising a tube settler (4) through which the drilling liquid can flow and beneath which a particle collection container is arranged for collecting solids separated from the liquid in the tube settler, wherein the solids collection container is a transportable container that is separate or separable from the tube settler. The invention further provides a process for the removal of solids from a drilling liquid using a separator, in which process a drilling liquid comprising solids is set to flow through a tube settler in order to allow the solids to settle out, thereby obtaining a solids depleted drilling liquid and an accumulation of solids. The invention also provides the use of a separator comprising a tube settler to remove solids from a drilling liquid.

Description

technical field [0001] The present invention relates to a separator for removing solids from drilling fluid, and a method for removing solids from drilling fluid and a method for removing solids from drilling fluid using a separator comprising a tube settler. solid application. Background technique [0002] When drilling a wellbore into an earth formation, drilling fluid is used to transport solid particulates produced by the drilling process from the downhole location being drilled to the surface. Typically drilling fluid is pumped down the hollow drill string to the drill bit. Solid particles produced by the drill bit, such as cuttings, are suspended in the fluid and flow to the surface as the fluid passes through the annular space surrounding the drill string. At ground level, either the liquid and entrained particles must be dumped, or the particles must be separated from the liquid to allow the liquid to recirculate. In the latter case, the separated particles must b...
