America Auger , Vermeer and Ditch Witch are top 3 directional drills manufacturer in the world, especially for the HDD application, water well, construction and other engineering.

All of the above HDD rig manufacturer has a lot of dealers all around the world, in some countries, there is still no exact regulation for HDD mud treatment; but in some HDD applications, mud recycling is necessary, plus more and more countries issued much more strict regulations on environment protection, used drilling fluids for HDD can not be disposal directly, you will need a HDD mud cleaning/recycling system. GN solids control is a specialized manufacturer for HDD mud cleaning/recycling system.

Agitator Impeller Shaft

GN mud agitator is made of explosion-proof motor, worm gear reducer. Impeller shaft, mounting plate, elastic coupling, and rigid coupling. Impeller shaft including impellers( single or double), shaft, stabilizer,etc. Impeller size depends on the customer’s mud density & viscosity&,mud tank size, it can be adjusted. Usually the impeller shaft diameter is fixed for same model, totally we have 4 models, JBQ5.5(7.5HP), JBQ7.5(10HP),JBQ11(15HP), JBQ15(20HP).

The keyed motor and driven impeller shafts are rigidly connected by a multi-piece coupling, which uses tapered locking bushings to secure the shafts together. Shaft lengths are customized to suit customer specifications. For shafts longer than 8’, a stabilizer is mounted on the tank bottom to support the lower end of the shaft.

Mud agitator impeller

GN mud agitator impeller is fixed to the shaft with bolts to avoid rotating or sway (connection with key groove optional). Its vertical location on the shaft is determined as a height from the tank bottom corresponding to the impeller diameter times 0.75. For example, a 20” impeller should be mounted 15” above the bottom. GN recommends straight impeller blades for tanks under 5’ deep and canted blades for deeper tanks. If dual impellers are desired, straight blades are mounted on the bottom and the canted blade impeller is installed at a point about two-thirds above the tank bottom.

Slurry separation equipment for TBM

TBM is short for Tunneling boring machines, which are used as an alternative to drilling and blasting (D&B) methods in rock and conventional “hand mining” in soil. Tunnels of less than a metre or so in diameter are typically done using trenchless construction methods or horizontal directional drilling(HDD) rather than TBMs.

GN designed and manufacturer a set of slurry separation system for TBM, below is the photo take at site. GN solids control can make customized design according to the client’s required treating capacity.

Centrifugal pump mechanical seal

Before packing material is the main seal for centrifugal pump in China, but in oilfield it is inconvenient to replace the packing seal time by time, it is too easy to damage, compare with packing, mechanical seal is much more durable, even if with high cost.

Centrifugal pump mechanical seals consist of two basic parts, a rotating element attached to the pump shaft and a stationary element attached to the pump casing. Each of these elements has a highly polished sealing surface. The polished faces of the rotating and stationary elements come into contact with each other to form a seal that prevents leakage along the shaft.

Mechanical treatment of the mud

There are 2 ways to treat the drilling mud, chemical treatment and mechanical treatment. Chemical treatment usually works together with mechanical treatment. Chemical treatment is to use chemical material to add into the drilling mud to get the ideal result.

Mechanical treatment is to use the 4-phase mud cleaning equipments , including shale shaker, desander, desilter, decanter centrifuge to separate large solids from the mud and keep the mud balance. If finally after centrifuge treatment, the mud will not be recycled and re-used, they may continue to use chemical treatment to get clean water and solids, the water will be drain off to the river and the solids will be used for cementing factory. GN solids control is the professional manufacturer and designer for the mechanical treatment system for the drilling mud.

Bentonite Recycling Equipment

Bentonite recycling equipment from drilling fluids maybe a equipment ( decanter centrifuge) or a complete unit(mud recycling system, including shale shaker, hydrocyclones, decanter centrifuge, mud tank, centrifugal pump,etc). Normally GN solids control will recommend a complete unit of mud recycling system, which can separate better.

Last week GN shipped one set of 500gallons/min mud recycling system to Australia, where have a lot of drilling companies.

Circulating system on a drilling rig

Circulation system on a drilling rig is the circulation of drilling mud during the drilling process. During drilling, it increased a lot of drilling mud with cuttings, the circulation system will use 4-phase or 3-phase separation equipments to separate the un-useful cuttings from it and get clean drilling mud to reuse for the drilling, the cuttings will be collected by a storage box for further process, so that it can meet the environment emission standard.

The circulation system produced by GN solids control usually include shale shaker, desander/desilter, ( sometimes we choose either of them or both of them), decanter centrifuge(depends on what kind of drilling you are doing).

Brandt 2 cone desander

Desander is the 2^nd phase of separation in drilling fluids circulation system for drilling rig. It is a completely mechanical equipment, do not consist of any electric or hydraulic drive.

The most common desander produced by GN solids control is composed of 2 desander cone, 1 bracket, solids discharge trough. Desander can be assembled by different qty hydrocyclones, e.g. 1pc cone with 500gpm processing rate, 2pcs cones with 1000gallons/min processing rate, 3pcs cones with 1500gpm process rate.

Except for desander, the 1^st phase of separation is shale shaker, the 3^rd phase of separation is desilter, the 4^th phase of separation is decanter centrifuge. The structure of desilter is similar with desander, just replace the 10” desander cone with 4” desilter cone.

Mezclador del lodo

Los mezcladors del lodos GNJBQ5.5, GNJBQ7.5, GNJBQ11, GNJBQ15 ofrece gran confiabilidad junto con la flexibilidad necesaria para satisfacer sus necesidades específicas.

El mezclador esta hecho de un hierro fundido muy resistente, con engranajes helicoidales que dan un funcionamiento más eficiente y una vida más larga. La unidad de configuración única permite el mantenimiento en la parte superior del tanque, eliminando la necesidad de inspecciones dentro del depósito. Disponible en el acoplador de eje o doble eje único.
