Mud System Can Be Used In Horizontal Directional Drilling, CBM
lebowski
Mud system is used not only for oil and gas drilling mud solids separation, but also can be used in horizontal directional drilling,CBM
What does mud system mean
A mud system, also known as oil drilling mud system is a control system specially desifned fotr oil gas drilling rigs. The system maintains the solids control and the overall performance of different quipment installed for the drilling fluid. The system is a single unit assembly of the well construction that remains connected with the wellbore in the drilling operation. A mud system is specially designed to operate according to the wellbore conditions.

Mud system in CBM equipment include:
1. Shale shaker, first-phase solids control equipment, separates the solid part of the drilling fluids greater than 75um and achieve dehydration capabilities under mechanical vibration principle.
2. Vacuum degasser, used for oil and gas drilling solids control, removes the mud, hydrogen sulfide, carbon dioxide and natural gas from the mud.
3. Mud cleaner, second-phase and third-phase solid control equipment for drilling mud barite recovery aggravated by pressure centrifugal sedimentation separation of solid particles larger than 15um above .
4. Centrifugal pump, also known as mixing pump, is ideal for mud supplying and jet mixing equipment.
5. Decanter centrifuge, depending on the treatment effect can be achieved with a medium or high speed centrifuges arranged in series and parallel manner 2um more subtle separation of solid particles.
6. Mixing devices include hopper, mud gun, mud agitator and mud jet mixing system.
As for the mud system in CBM, they should be equipped with in accordance with customer’s practical solid-liquid separation demand in application, using the most reasonable design to meet customer demand for recycled fluids or solid-liquid separation.
Process of Aipu solids control system
1. Drilling fluid from drill hole will feeding into shale shaker buffer box by pipeline, the shaker can install shaker screen mesh API 35 to API 120 to separate larger drilling cuttings. Fluids part will drop into sand trap through mesh screen panel.
2. drilling mud from sand trap will over flow into next compartment and vacuum degasser will suction mud to degasser and treated mud will overflow into degasser compartment.
3. Desander feeding pump will suck mud from degasser compartment and feed into desander cyclone for 47 – 76 micron separation. Solids part will drop from desander nozzle and fluids over flow into desander compartment.
4. Another will pick up mud from desander compartment and feed desilter cyclone, solids part drop through desilter nozzle and fluids over flow into desilter compartment.
5. Submersible slurry pump or screw pump then transfer mud from desilter compartment into decanter centrifuge for 2 – 7 micron separate and clean mud flow into centrifuge compartment
6. All tanks compartment after desilter compartment we name as clean mud, mixing pump can suction or discharge to any of the clean mud tank for mud transfer or new mud mixing.
Aipu solids control system is optimal solution for you to process well drilling fluids. From the shaker, cleaner, to centrifuge; from shaker screen, spring, to valves spare parts. If any demand,please contact us directly
