Now more and more clients from China recognise GN as an international brand. More and more local big companies comes to GN for a solution, especially the people who heard GN international brand.HDD mud recycling system is one of GN main separation solution for no-dig drilling mud recycling and cleaning. This week, GN finished the fabrication of one set HDD mud recycling system for Sinopec. Now the system is in GN assembling workshop waiting for delivery.


To make it more proper for transportation, it have been designed as containerized system, container sized tanks, frames, and all the equipment built into. As most of the times, the 500gpm standarized equipment as below.


Shale shaker GNZS703F is the first stage separation equipment to remove the coarse solids. GNZJ703F-1S8N mud cleaner 2 units centrifugal pump are equipped in the system for feeding the drilling mud to the hydrocyclone units for smaller sand and silt separation. Decanter centrifuge GNLW363C-VFD is last stage sepa.ration equipment for fine solids separation
Well it is still not a must for all the equipment, depends on clients requirement, mixing section, desander desilter section can be optional, but normally when our clients want to do this, we need make sure there is enough reason to do this, or the whole system will not be capable to the job.
Free pre-sales consultancy from GN professional sales team, contact us when you are interested in.

Under the requirement of environmental regulation, vertical cutting dryer (vertical centrifuge ) is gained much attention from public. Cutting dryer is one kind of solution to deal with the oil based mud and synthetic base mud. Recently, GN Cutting dryer is also tested with water based mud which is widely recognized as  harder mud to separate solids without clogging. It is widely acknowledged that only high functional cutting dyer is able to deal with water based mud so GN cutting dryer is able to absolutely separator all kinds of mud

Compare to CSI Cutting Dryer, GN cutting dryer advantages

GN cutting dryer process water based mud

GN cutting dryer process water based mud

1.  GN vertical cutting dryer is install air knife and flushing system to prevent screen basket from plugging

2. Discharge screw conveyor is a good solution to transport the solids from the dryer to discharge site

3. Carefully select the material of flights and design the screen opening distance assure historically and consistently produced as low as 5% oil retention on cuttings by weight. GN  also provides parts and service for cuttings dryers.

GN also supports a plenty of solids control equipment to work with cutting dyer. GN not only provide the single device, but focus on offering a completely solution to your working site such as bored pile mud solution, diamond drilling mud recycling , dredging slurry separation, HDD(Horizontal Directional Drilling) and CBM

(Coal Bed Methane).  GN Solids Control will be your best partner in the solids control field.

Bored Pile Construction

Double Deck Mud Cleaner

Bored pile is widely used in massive civil infrastructure and industrial construction such as the tall building or bridge work. Less disturbance surrounding soil, little noise and  much economic drilling than the conventional drilling are the main advantages of bored pile. However, drilling engineers have to do mud investigation and decide which drilling technology has to be carried on. Piling contractors decide the correct drilling technology and solids control equipment minimize influence on the environment and reduce the cost.

GN double deck shale shaker with hydrocyclone is  perfect solids control system matching with the bored pile. The working function will be introduced below

Function

drilling mud is pumped to bottom deck (2) shaker screen separate large particle to disposal site and fluid penetrate to mud tank(3), the slurry pump(4) will transfer drilling fluid to desander cone(5) for further separation. The solids/sand will be separated on the top deck (6) to discharge. The cleaning fluid will store in tank (7)

Schemetic

Schemetic Graph

It is a compact and economic design. The smart solids control system  wins massive compliments from our clients. Please contact with us if you need more information.
