Desander is the second equipment in solids control system, it is used to separate the solid phase particles whose diameter is more than 44μm from drilling fluid. Desander is the combination of hydrocyclone and shale shaker. The main body can be separated into two parts, the above part is the hydrocyclone and the bottom is the circular 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 along the wall, the bigger solid particles along the wall of hydrocyclone sink spirally under the centrifugal force and gravity, and to be discharged from the bottom flow hole and fall on the under micromeshsieve for separation. The other mediums rise along the spiral of hydrocyclone, flow into the third class separation equipment-desilter for a further cleaning treatment from the overflow hole. The above procedure guarantees the mud can be well handled in the next equipments and decrease the workload.

The above procedure guarantees the mud can be well handled in the next equipments and decrease the workload.

Desilter is the third class equipment in solids control system, it is used to separate 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 along the wall of hydro cyclone sink spirally under the centrifugal force and gravity, and to be discharged from the bottom flow hole and fall on the under micromesh sieve for separation. The other mediums rise along the spiral of hydro cyclone, flow into the fourth class separation equipment-centrifuge for a further cleaning treatment from the overflow hole.

Mud Cleaner is the second class and the third class solid control 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 class and the third class solid control 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.

This pump has a strong adaptability to medium, smooth flow, small pressure fluctuation and high suction capacity. With unique design of rotor and stator, low rate of pump internal flow and more stable pressure. Screw and machine body are made of stainless steel material which is corrosion resistant and has a long service life. With few spare parts ,simple maintenance, easy to be replaced and maintained , compact structure and small footprint. The advantages of screw pump are compact structure, small volume and easy maintenance. Rotor and stator, wearing parts of this pump, are convenient to replace

Vacuum degasser can wipe off the invaded gas from drilling mud quickly, restore drilling mud proportion, keep mud viscosity performance and improve the quality of drilling fluid. Vacuum degasser utilizes vacuum pump suction action, causes negative pressure zone in vacuum tank, under the action of atmospheric pressure, drilling mud through the suction pipe into the hollow shaft of rotor, and then through the window around hollow shaft jilt to the tank wall by spurting. Due to the effect of collision and separation wheel, separating drilling mud into thin layer, the invaded bubble 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 by impeller. Because of the main motor first start, and the impeller which connected with motor is high rotation speed, so drilling mud can only from the suction pipe into the tank, not be inhaled from drain pipe.

Mud agitator, also called drilling mud agitator, used for drilling fluid agitation mix, prevent drilling fluid solid particles in the tank circulation system deposit, cycle drilling fluid performance stability, mixed evenly. Mud agitator composed by explosion-proof motor, reducer, engine base 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 can make the mixing liquid to produce the vortex motion, thereby enhancing the mixing effect.

Directional boring, commonly called horizontal directional drilling or HDD, is a steerable trenchless method of installing underground 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 boring is used when trenching or excavating is not practical. Directional boring minimizes environmental disruption. It is suitable for a variety of soil conditions and jobs including road, landscape and river crossings. Installation lengths up to 6,500′ (2,000m) have been completed, and diameters up to 56″ (1,200mm) 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.

Mud tank is a container, typically made of square steel tube and steel plate, to store drilling fluid on a drilling rig. Mud tanks play an important role in solids control system. It is the base of solids control equipment’s, and also the carrier of drilling fluids. Mud tank is an important part in the solid control 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 operation of circulating drilling fluid during drilling process. 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. Chemical 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.

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. It is the preferred equipment to dry drilling cuttings, recycle drilling fluid and especially recycle oil base drilling fluid.

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.
