Solid Control & Drilling Waste Management Solution

Drilling mud recovery Most OBM drilling mud is disposed once drilling work finished. In contrast, much oil-based drilling mud and synthetic-based drilling mud is recycled possible. Sometimes the physical and chemical properties of the used drilling mud have degraded somewhat, and the drilling mud must be processed to rejuvenate the necessary properties. In other cases, drilling mud have been degraded sufficiently that it cannot economically be reused as new drilling mud. There are many relatively simple processes that can be used on drilling rigs to capture clean drilling mud that would otherwise be discarded and return for reuse. Like pipe wipers, mud buckets, and vacuuming of spills on the rig floor. Recovery of mud during tank cleaning may also allow the mud to be reused. Solids control equipment, like centrifuges, can be used to remove solids from the recirculating mud stream. Some new dri...

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 The liquid mud passes through the screens and is recirculated back to the mud tanks from which mud is withdrawn for pumping downhole.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 ...

Application KOSUN mud agitator is part of the drilling fluids solids control equipment ,which is mainly used to agitate and mix the drilling mud to prevent solid particles settlement in circulating tank. Mud agitator is composed of explosion–proof motor, speed reducer, motor base and blade.The connections between motor and speed reducer, speeder reducer and impeller shaft by steel coupling.The impeller is welded by four blades. Structure Mud agitator mainly consists of explosion-proof motor, reducer, motor base and impeller assembly, solid couplings are used to join motor with reducer, and reducer with impeller shaft. Four vanes are installed and welded to form the impeller. Working Principle The impeller makes the fluid in vortex motion and improves the agitation effect. The pallet among the vanes can prevent solid particles in mud from depositing around the lower vanes after shutdown, which reduces the moment of resistance of deposits agai...

  KOSUN high effective mud cleaner is the second or third stage s olids control system equipment of drilling mud , which will deal with the drilling   mud after being treated by the first stage s olids control system equipment. The barite will be recovered and drilling cuttings which are bigger than barite will be removed. Then the barite in the underflow will flow into circulation tanks through the shaker screens when the weighted mud passes while the particles that are bigger than mesh will be removed.   KOSUN desander is used as the second  stage of solids control system for drilling mud, which makes separations between 40 and 100 microns.   KOSUN desilter is used as the thir d stage of solids control system for drilling mud, which make separations between 15 and 44 microns. 1. Polyurethane (PU) Material for desander and desilter cones. 2. Desander cones can be installed between one and three 10 ” desander cones, each cone can process 5...

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...

Linear motion shale shaker  is  the  first stage  solids control equipment in drilling fluid   processing system, well  known as solids treating  equipment in solids control system . Linear motion shale shaker  decides the performance of the whole solids control system . Linear motion shale shaker  for solids control system   remove s  dril l  cuttings from drilling fluid during   mud circulat ion  and drilling.  Controlling the solids in drilling fluid is important to control  drilling  cost and protect environment. Linear m otion s hale s haker s typically consist of wire mesh shaker screens in  various mesh sizes that shake or vibrate the drill cuttings  which across and off the screens as the drilling fluid or drilling mud flows through shaker screen  and back into the drilling mud  system. This separates the solid drill cuttings from the fluid so that it can be recircu...
