Desander hydrocyclone function with optional pair with shale shaker

Solids control separation and drilling mud recovery and reuse is the critical parts of drilling operation due to the drilling mud is serving as lubricant to making the drill bit dill more smooth and also serve as cooling agent to prevent overheat of drilling bit that will cause damage of drilling bit and the oil-well as well.  There are 4 stages of solids control for drilling mud and requires 4 machineries to do the solids separation in the drilling mud:  Shale shaker, Desander, Desilter, and Decanter Centrifuge.  GN Solids America LLC as manufacture of these machineries offer transparent pricing policy and offer full after service capacity as just like other US manufactures.

shale shaker

As you are aware the steps of needs on solids control for drilling mud, the desander is the 2nd step of needed on solids control machinery.  GN Solids America LLC's concept of desander machinery is using 10" size hydrocyclone that create centrifugal force by using centrifugal pump feeding the drilling mud into the 10" hydrocyclone.  The numbers that need of 10" hydrocyclone is depends demand of treating capacity of drilling mud.  GN Solids America LLC offer desander that can manage 120, 240 and 360 (m3/h) by offer 1, 2 and 3 desander hydrocyclones in bracket .  To take the solids control of the drilling mud even further, GN Solids America LLC offer the optional shale shaker to pair with desander to do more through solids control drill cutting separation.  The 10" hydrocyclones can perform to remove the size of  drill cutting in the mud by down to 45 microns.  GN Solids America LLC offer various  model of shale shaker with multiple layers of screens panel. This combo unit is functioning as both primary shale shaker and desander unit in one. The drilling fluids gets into this de-sander unit via the mud distributor pipe and then flow on the bottom layer screen firstly for primary solids control. Liquid gets through the screen mesh and falls down to the under located mud tank.

Water recycling system for TBM Pipe Jacking Machine

Huge water consumption had been considered more and more for TBM projects, it will be a waste of money for the TBM contractors, they need a proper way to recycle the water to reduce the total cost and reduce the impact on the environment.

Herrenknecht AG is one of the best TBM pipe jacking machine in the world, nowadays more and more contractors try to source the pipe jacking machine in China, because some good Chinese TBM manufacture improved the underground technology and quality a lot to make their machine competitive.

GN solids control design and produce mud cleaning system/ water recycling system for TBM/ Tunneling and drilling waste management system. The normal design is with mud cleaning system and dewatering unit with dewatering decanter centrifuge, and water storage tank is included in the system to reserve the water, which could be reused for the TBM.

We provide 2 types of dewatering unit, one type is containerized dewatering unit with everything inside the container, to prevent sun/ water/ rain/ cold temperature. The other type is without container, the cost is cheaper, but you need to install a sun proof cover on top of the dewatering unit in the jobsite.

GNLW553C-VFD decanter centrifuge is the most common used decanter centrifuge for dewatering unit. It is the biggest model centrifuge we have now, the treating capacity varies for different mud, when it is used for drilling fluids, the treating capacity could reach 90m3/h, when it is used for TBM without dewatering unit, the treating capacity up to 60m3/h, when it is working with dewatering unit, the treating capacity will reduce a lot to 40m3/h, it depends on the mud weight and density.

If you need to recycle the water for TBM projects or bored piles or other underground constructions projects, pls contact GN solids control for a customized solution. 

Drilling cuttings solidification unit and cuttings disposal solution

Drilling cuttings solidification unit is one of the solution of cuttings disposal, it is also called stabilization unit. It is an effective solution for both water based cuttings disposal and oil based/ synthetic based cuttings disposal.

Why should we pay more attention of cuttings disposal?

Obviously, The waste cuttings will damage the environment, lead a heavy pollution and contaminate the under groundwater and influence the Sustainable Development.

There are 4 common ways for the drilling cuttings disposal”

(1)   Thermal Desorption Unit, Mechanical separation of drilling cuttings waste treatment with dewatering unit, which is the most popular solution right now

(2)   Cuttings re-injection (CRI)

(3)   Bio-remediation

(4)   Solidification unit/ stabilization unit

 

GN solids control is specialist for the mechanical separation of drilling cuttings. GNCM-40A & GNCM-40B is our standard drilling waste management system for oil based drilling cuttings, especially for international client, it is design suitable for container shipment. The main difference between them is the installation of the decanter centrifuge, the centrifuge is installed on the telescopic skid in proposal A, the centrifuge is installed on the catch tank on proposal B, they are 2 main methods in the existing projects.

The modular drilling waste management unit including high-G drying shaker unit and decanter centrifuge telescopic skid unit are the main equipments for water based cuttings treatment.

After treated by GN drilling waste management unit, solidification unit will be used for water based mud, and thermal desorption unit will be used for OBM and SOBM. The OOC in the discharged dry cuttings from the vertical cuttings dryer is under 5%, sometimes it reach 3.7%, in some countries, it is acceptable for environmental standard for land filling. In some counties where has more strict environment standard for the cuttings disposal, a further equipments TDU is necessary.

GN Solids Control, as TOP solids control manufacturer in China, has been the equipment supplier of the oil service companies for many years.Usually, in order to provide a better after sales service, GN Solids Control sends a checklist for customer to fulfill.
