About microtunneling

Microtunnelling is a nature method of construction using pipe jacking. In many countries and areas, it also defined as a “Trenchless Construction Method”.

Slurry separation system for microtunneling

Microtunnelling project usually takes in urban district. In this case mud system matched for microtunneling request compact and a very small footprint recirculation slurry system with different capacity. This kind of mud system usually called as “slurry separation system”.

Features of slurry separation system

1) Steel Frame Screen with large open microns usually used.

As the solids usually bigger than oil and gas drilling, solids content higher and many bigger size sands / solids. And it is big diameter well with smaller depth, no higher request for mud quality. It is no need to separate very fine. And steel frame have a longer lifetime for microtunneling.

2) Compact system with smaller footprint: all separation equipment combined together, a storage tank and a mixing tank.

Usually, GN only offer separation plant and equipment for mixing part. And recommend users to build storage / mixing tank locally to save cost.

3) Big size hydro cyclones for large capacity. And it is not easy to be blocked.

GN Solids Control also have very good busines in Nigeria for Solids Control Equipment & Decanter Centrifuges.

About GN Vertical Cuttings Dryer:

In drilling operations, typical solids control equipment discards 1-4 barrels of liquid for each barrel of solids removed.GN drilling cuttings dryer system consisting of Vertical cuttings Dryer and the relevant equipment could discharge 1 barrel of liquid for 3 barrels of solids removed.GNCD930 has proven to reduce this liquid to below 3% by weight by site test：

• 1) Reduce the amount of OBM or SBM on cuttings discharge to reduce waste volume and meet environmental objectives.

• 2)  Recover valuable base fluids for reuse and lower the cost.

• 3)Reduce fluid content prior to other treatment, thereby increasing process capacity.

GN Vertical Cuttings Dryer Structure Features:

In short，GNCD930 Vertical Centrifuge could help you meet environmental objectives by reducing waste volume, maximizing liquid recovery and reducing your project cost.GN Solids Control can provide all-around mud recycling and treatment equipment.

n the design process of GNCD cuttings dryer, user maintenance is taken into full account. All wearing parts are easily removable belt can also be replaced without disassembling the gear box, and the gear box part can easily be removed.

GNCD dryer is designed for high-speed rotation industry work, and take full account of the dynamic balance. Each rotating parts have been done a dynamic balance, in order to ensure that the replace part does not affect the whole dynamic balance.

The gear box is used to offer differential speed between screen basket and screw pusher. As the gear box is an integral structure, whole replacement is required. GNCD dryer has independent external circulating oil lubrication system. The lubricating oil pump and the filter device are arranged outside the GNCD dryer for easy operation and maintenance. To ensure sufficient lubrication for gear box and bearings, a pressure control switch and the flow control switch is needed in this lubrication system. To ensure the normal lubrication, these switches are connected with host or alarm.

The horizontal Solid Bowl decanter centrifuge design by GN Solids Control is very popular for oilfield drilling mud solids control application of drilling waste management system.

The centrifuge are the solid bowl, horizontal, continuous feed, scroll type specifically designed for drilling mud processes to continuously separate one solid and one liquid phaseMounted on a rugged, portable skid made of a fabricated carbon steel base with 304 stainless steel wetted parts.

Solid bowl decanter type centrifuges often will dewater materials which are too fine for effective dewatering by filtering centrifuges.

In decanter-type units, extraction of liquid takes place in the cylindrical part of the bowl. Dewatering of solids by compression of the cake takes place in the conical part of the bowl. Bowl geometry must be adapted to achieve optimum results for the desired application.

The solid bowl decanter centrifuge consists of two horizontal concentric rotating elements contained in a stationary casing. The outer rotating bowl element is tapered so that the solids discharge from a smaller radius than the liquor. The inner element is a hollow hub screw conveyor with blade tips shaped to fit closely to the contour of the bowl. Feed slurry is introduced into the conveyor hub. The feed accelerates to the machine speed the slurry is delivered by centrifugal force into the rotating bowl by way of ports in the conveyor hub. The solids settle through the liquor pool formed on the wall of the bowl. The solids are then conveyed, due to a slight differential between the screw and bowl, up the drying beach to the solids discharge ports. The clarified liquors are discharge in the opposite direction from adjustable overflow ports.

For a longer lifetime and reliable performance, suitable and on time operation and maintenance on decanter unit is essential. Below instruction from work top cantrifuge manufacturer- GN Solids Control

Operation

A. All safety protection guards shall be installed before starting up. It is forbidden to open the guards of decanter centrifuge to observe the running state of the machines.

GN Screw Conveyor Summary 

Generally speaking A screw conveyor or auger conveyor is a mechanism that uses a rotating helical screw blade, called a “flighting“, usually within a tube, to move liquid or granular materials. They are used in many bulk handling industries. Screw conveyors in modern industry are often used horizontally or at a slight incline as an efficient way to move semi-solid materials, including food waste, wood chips, aggregates, cereal grains, animal feed, boiler ash, meat and bone meal, municipal solid waste, and many others. The design of the conveyor is dependent on operating conditions, the type of transported material and its properties. Traffic enforcement can be controlled by changing the speed of propulsion.

Screw Conveyors main parts

♦ Conveyor Body (tube or trough)

GN Shearing pump saves the cost of mixing polymers and clays while improving mud properties. Shearing the polymers eliminates fish eyes and prevents polymer chaining (long strings), which cannot pass through the shaker screens. The Shear pump is available as a belt-driven or diesel-driven package including a mud hopper, mud gun, and transfer line orifice plate. A complete system with skid, tanks, and piping are also available.

Feartures of GN Shear Pump

The GNJQB6545 shear pump adopts a set of compound seal for no leakage at stuffing box. Inside pump is a 300series stainless steel turbine containing 44 nozzles, four scoops and shear plate. Fifty(50)% of the fluid is sheared twice each time through the pump. This turbine shear pump is mounted on a special base with belts and sheaves to drive pump, OSHA type belt guard and a 75HP(55KW)1800RPM EXPLON PEROOF U/L approved electric motor, 460 volt, 3 phase 60 cycle. Included is a special hopper(ZHP150) with nozzle sized for this
application and one mud kit as a package in order to build a complete shear and hydration system. The pump is designed to give longer service life through the improved.

Principles of the installation for shear pump

There are many principles of proper pump installation and application as well as special considerations for the pump design which, if followed, will further enhance the performance of your GNJQB turbine shear pump.

The pump should be located the liquid source so that the suction line can be short and reduce loses. The foundation should be sufficiently rigid and substantial to adsorb any vibration and support the base plate at all points. The base plate should be installed in a level
position.

The capacity of a centrifugal pump should never be adjusted by throttling the suction line, but a positive shutoff valve of a type to cause minimal turbulence should be installed in the suction line to permit the closing of the line for removal of the pump for inspection and maintenance.

The mud mixing system normally use shear pump to connect with hopper for mixing.
