Oil drilling mud purification equipment development

By using proper solids control techniques maintenance cost of drilling fluids, disposal and clean-up. cost can be minimized dramatically. In late nineteenth century oil industry realized the importance of these facts while separation of cutting from borehole was going on by using open earth pits.

shale shaker

Settling of solids due to gravity was allowed by the settling pits and series of weirs completed the process of solids control. To re-pump the clean mud down the hole, it is sent into the suction pump. This marks the beginning of using first solid control technique.

Introduction of shale shaker in early 1930 signifies the innovation for oil industry.

Technologies applied in mining industry were used to derive shale shakers.
In today's world solids control is the basic solids control equipment used in oil industry.

Hydrocyclone or clone classifier was another machine used in 1930 hired from mining industry.

It works on the principle involving centripetal force that causes spinning of drilling fluids in the cone with high velocity compelling the settling of heavier soilds downward. Use of combination of drilling shale shaker with hydrocyclone becomes important part of solids control system.

Today’s solids control system includes formation of system of closed loop which permits enhancement in environment control and decrement of potential for drilling fluid spills.

Drilling Fluids Mixing Mud Gun Maintenance

Drilling fluid mud gun is used to provide supplemental or primary mixing in mud tanks depending on the number being used and the pit size. They are best used in the drilling fluids circulation mud tank corners to keep solids from settling with a drilling fluid mud agitator placed in the tank center. The oilfield drilling mud gun in the drilling mud system is also used to transfer drilling fluids from compartment to compartment, like for trip tank compartment.

Mud Gun

Drilling Fluids Mixing Mud Gun Maintenance:
1. Grease the swivel once a week and add shots of a multi-purpose grease.
2. Visually inspect the mud gun assembly for any leaks, loose fittings once a week.
3. Inspect mud gun jet nozzle for excessive wear once a month.

Once installation is complete, the unit can be started by turning the feed pump on. The direction of discharge may be modified to suit the operators requirements by rotating the swivel.

As the China solids control leader and drilling waste management expert, KOSUN provides all the drilling solids control equipment for the drilling fluid circulation system, all the products can be manufactured on the requirements of the customers.

Vertical centrifuge for oil based drilling waste management

Drilling waste management equipment Vertical Centrifuge is also called Vertical Cutting Dryer,it is a innovative design which fit for Oil based drilling waste management.Drilling cuttings from the primary solids control equipment like shale shakers,mud cleaners which is picked up by Auger(Screw) conveyor and transfer to feeder of the vertical cutting dryer.

Vertical Cutting Dryer

Vertical Centrifuge uses centrifugal force to dry drilled solids in oil or synthetic base fluids. A stainless steel screen bowl traps “wet” solids and accelerates them up 900 RPM. Liquid is forced through the screen bowl openings, while “dry” solids are extracted by the angled flights attached to the cone, which rotate slightly slower than the bowl. Tungsten carbide protects the flights from abrasive solids and ensures long operational life. This aids in maintaining a constant gap between the scroll and screen bowl, which is crucial for proper operation.

Designs of vertical centrifuge:

1. Air knife is firstly installed the dryer which is consistently used for cleaning the screen during the work to prevent the viscous oil-based mud from blocking the screen. Precision design for angle and distance make sure air knife efficiently wipe out the sticky mud on the screen.
2. Cleaning pump will provide the high pressure water and vertical angle effectively to get rid of accumulated solids in the screen
3. Two augers are equipped at the bottom to continually transport disposal solids to the site which is suitable for handling a large amount of mud.
4. Oil cooling and lubrication system ensures the long operation life and reliable motor performance.
