Drill Cuttings Separation from Drilling Mud

Drilling mud is used to control subsurface pressures, lubricate the drill bit, stabilize the well bore, and carry the cuttings to the surface, among other functions. Mud is pumped from the surface through the hollow drill string, exits through nozzles in the drill bit, and returns to the surface through the annular space between the drill string and the walls of the hole.   As the drill bit grinds rocks into drill cuttings , these cuttings become entrained in the mud flow and are carried to the surface. In order to return the mud to the recirculating mud system and to make the solids easier to handle, the solids must be separated from the mud. The first step in separating the cuttings from the mud involves circulating the mixture of mud and cuttings over vibrating screens called shale shakers. The liquid mud passes through the screens and is recirculated back to the mud tanks from which mud is withdrawn for pumping downhole. The drill cuttings remain on top of the ...

Shale Shaker Screens Types and Application

S hale shakers typically consist of wire mesh  shaker screens  in various mesh sizes that shake or vibrate the drill cuttings which across and off the shaker screens as the drilling fluid or drilling mud flows through shaker screen s  and back into the drilling mud system.  There are mainly three types of shaker screens for different types of shale shakers, like PWP screen, PMD screen, and hook strip screen. PMD screens are Derrick ’ s patented products for Derrick 2000 series and Derrick 500 series shale shakers . While PWP and hook strip screens are widely used for world famous shale shakers like brand M-I SWACO, Derrick, Brandt and KOSUN. Hook strip s creen s  is a  common kind of s hale s haker s   s creen, which can be widely used in different conditions in drilling operation. This screen is constructed with two  or three layers of stainless steel wire cloths bonded to a steel...

Drill Solids Cuttings Separation from Liquid Drilling Mud

Drilling mud is employed to regulate subsurface pressures, lubricate the drilling bit, stabilize the well bore, and carry the drill solid cuttings to the surface, among alternative functions. Drill mud is pumped-up from the surface through the hollow drill string, exits through nozzles within the drilling bit, and returns to the surface through the ring-shaped   area between the drill string and also the walls of the outlet. As the drilling bit grinds rocks into drill cuttings, these drill cuttings become entrained within the mud flow and area unitcarried to the surface. so as to come the mud to the recirculating mud system and to create the drill solids easier to handle, the drill solids  should be separated from the mud. the primary step in separating the drill cuttings from the mud involves current the mixt...

Drilling Waste Management Processing Craft Description

During oil & gas exploration and production, there are lots of drilling cuttings  and fluid  generated. These drilling waste will leak into earth with time going which is great harm to surface and ground water and the surrounding environment even causes pollution, especially in sensitive area harmful to human health and life. Therefore, it is crucial important to drilling waste management before discharged. Here is a simple processing procedure for drilling waste management. The screw conveyor mounted under the shale shaker is used for collecting drilling cuttings from shale shakers and mud cleaners (desander or desilter), then convey the drilling cuttings to the H-G dryer for solid-liquid drilling waste management . There is one conical buried tank under the shale shakers for discharging mud and alleviate the grit in mud tank. Otherwise, if serious grouting off happened, the overflow mud will enter into the conical buries tank to prevent mud grounding...
