METHOD AND APPARATUS FOR FLUID DISTRIBUTION IN SHAKER

摘要

A shaker for separating solids from a drilling fluid includes a top screening deck, a flow-back pan positioned beneath the top screening deck for receiving an initially separated drilling fluid from the top screening deck. The flow-back pan is divided into a plurality of channels. The shaker further includes a fluid distribution box, which includes a plurality of conduits. Each channel of the flow-back pan corresponds to one of the plurality of conduits in the fluid distribution box and each channel communicates a stream of the initially separated drilling fluid to the corresponding conduit. The shaker further includes a middle screening deck and a bottom screening deck. Each conduit routes the stream of initially separated drilling fluid to a corresponding one of the middle screening deck and the bottom screening deck.
