what equipment is used to control solids in a mud system

MUD EQUIPMENT

1) Shale Shaker

The shale shaker is the first stage of solids command equipment in drilling purification organisation,also known as key solids control equipment in drilling mud system used for separating larger cuttings above 75 μm brought from the drilling well to leave the liquid with smaller particles into the tanks below, which will flow into next grade solids control equipment for further handling..The shale shakers produced by united states of america accept the advantages of large handling chapters, screening high precision, depression-energy, environmental protection.

2) Desander

Desander is the second equipment in solids control organization, it is used to separate the solid phase particles whose diameter is more than than 44μm from drilling fluid. Desander is the combination of hydrocyclone and shale shaker. The main body can be separated into two parts, the higher up part is the hydrocyclone and the bottom is the round shale shaker. The vibration exciter is driven by a vibration motor to keep the whole screen box vibrate with a forward circular track.
The mud produces pressure and speed when it passes the centrifugal pump, and flows into the hydrocyclone forth the wall, the bigger solid particles along the wall of hydrocyclone sink spirally nether the centrifugal force and gravity, and to be discharged from the bottom menstruation hole and fall on the under micromeshsieve for separation. The other mediums ascent forth the screw of hydrocyclone, flow into the tertiary class separation equipment-desilter for a further cleaning treatment from the overflow pigsty. The above procedure guarantees the mud can be well handled in the next equipments and decrease the workload.

3) Desilter

Desilter is the tertiary form equipment in solids control system, it is used to split up the solid particles whose diameter is 15-44μm from drilling fluid.Desilter is designed by the theory of particle sedimentation. The separation medium-drilling fluid produces some pressure and speed when it passes the centrifugal pump, and flows into the hydro cyclone along the wall, the bigger solid particles forth the wall of hydro cyclone sink spirally under the centrifugal force and gravity, and to be discharged from the bottom menstruation hole and fall on the under micromesh sieve for separation. The other mediums ascension along the spiral of hydro cyclone, catamenia into the 4th class separation equipment-centrifuge for a further cleaning treatment from the overflow pigsty.

4) MUD CLEANER

Mud Cleaner is the 2nd grade and the third class solid command equipment which are combined from desander ,desilter and underflow screen to treat the drilling fluid . It occupies small space and the function is powerful, mud cleaner is the ideal device of the second grade and the third class solid command to treat the drilling mud. Multi-functional mud cleaners are designed to be combined with desander, desilter , pressure pump , the bottom slot ,an Underflow shale shake , a bracket and a base of operations.

five) SCEW PUMP

This pump has a strong adaptability to medium, smooth menstruation, pocket-size pressure fluctuation and high suction capacity.With unique pattern of rotor and stator, depression rate of pump internal catamenia and more stable force per unit area. Screw and auto body are made of stainless steel material which is corrosion resistant and has a long service life .With few spare parts ,elementary maintenance, easy to be replaced and maintained , compact structure and small footprint. The advantages of screw pump are meaty construction, small book and easy maintenance. Rotor and stator, wearing parts of this pump, are user-friendly to supervene upon

6) Vacuum Degasser

Vacuum degasser can wipe off the invaded gas from drilling mud quickly, restore drilling mud proportion, keep mud viscosity functioning and better the quality of drilling fluid. Vacuum degasser utilizes vacuum pump suction action, causes negative pressure zone in vacuum tank, nether the activeness of atmospheric force per unit area, drilling mud through the suction piping into the hollow shaft of rotor, so through the window around hollow shaft jilt to the tank wall past spurting. Due to the effect of collision and separation cycle, separating drilling mud into thin layer, the invaded chimera broken and gas escape. Through the vacuum pump suction and gas water separator separation, gas escape to safety zone, and the drilling mud is discharged to tank outside past impeller. Because of the main motor get-go start, and the impeller which continued with motor is high rotation speed, and then drilling mud can only from the suction pipage into the tank, not be inhaled from drain pipe.

vii) MUD Agitator

Mud agitator, also called drilling mud agitator, used for drilling fluid agitation mix, prevent drilling fluid solid particles in the tank circulation organisation deposit, cycle drilling fluid functioning stability, mixed evenly. Mud agitator equanimous by explosion-proof motor, reducer, engine base of operations and impeller components four parts. The motor and the speed reducer, reducer and the impeller shaft are connected through rigid coupling. Impeller consists of four blades welding formed. The impeller tin make the mixing liquid to produce the vortex motion, thereby enhancing the mixing effect.

viii) HDD

Directional boring, commonly chosen horizontal directional drilling or HDD, is a steerable trenchless method of installing hugger-mugger pipes, conduits and cables in a shallow arc along a prescribed bore path by using a surface launched drilling rig, with minimal impact on the surrounding area. Directional dull is used when trenching or excavating is non practical. Directional tiresome minimizes environmental disruption. It is suitable for a variety of soil conditions and jobs including road, mural and river crossings. Installation lengths up to 6,500' (2,000m) have been completed, and diameters upwardly to 56″ (i,200mm) have been installed in shorter runs. Pipes can be made of materials such as PVC, polyethylene, Ductile iron, and steel if the pipes can be pulled through the drilled hole.

nine) MUD TANK

Mud tank is a container, typically fabricated of square steel tube and steel plate, to shop drilling fluid on a drilling rig. Mud tanks play an of import role in solids control arrangement. It is the base of solids control equipments, and also the carrier of drilling fluids. Mud tank is an important part in the solid command system.Based on functions, mud tank includes metering tank, circulating tank, chemical tank, aggravating tank, precipitating tank, storing tank, etc.Metering tank is used for perfusion fluid metering.
Circulating tank is used in store normal performance of circulating drilling fluid during drilling procedure. Normally the shale shaker and vacuum degasser and desander are mounted together on the same circulating tank, while desilter and centrifuge on the second circulating tank.
In general, chemical tank's roof is mounted with shear pump. Chemic tanks are used for adding chemicals into drilling fluid. Aggravating tank is used to configure weighted drilling fluid.
Reserve tank used for storing drilling fluid.

x) VERTICAL CUTTING DRYER

A vertical drilling cutting dryer is a kind of separation equipment which utilizes mechanical rotary produce centrifugal force to realize. The advantages of the equipment are adaptable, better treating efficiency, stable working, and long service life and can effective recycling the drilling fluid in drilling cuttings. Information technology is the preferred equipment to dry out drilling cuttings, recycle drilling fluid and particularly recycle oil base drilling fluid.

eleven) JET shearing device

The Technoflo jet shearing device system is a unique design with most effective and economical means of hydrating polymers and improved mixing with instantaneous results. The low pressure high volume Technoflo shearing mixer, mix dry materials into liquids and blend, shear drilling fluids.
Advantages includes, Shearing of long chain polymers, mixing & shearing additives Hydrate and Disperse polymer, reduce production settling, like shooting fish in a barrel maintance, no moving parts, saving cost.

12) Screw conveyor

Screw Conveyor is normally known every bit Auger,it is a widely used conveyor equipment. Compared with other conveyor equipments, it has the advantages of small size, good sealing, stable and reliable functioning, much belch loads and unloads prophylactic operation and easy maintenance.
