Each year, GN Solids Control produces and provided more than 200 sets for shale shakers for drilling rig solids control systems in more than 70 countries and regions in the world. Some equipment are exported together with GN’s system, some are exported separately to replace the old ones for existing system, or when clients are building tanks locally.

GN Shale Shaker System for Australia
Recently, just in last month, GN Solids Control has shipped a complete mud solids control system to an Australian drilling company, and this system now is approaching the destination port in Australia, and is schedule to be put into use in early March. Besides the basic functions a solids control system could provide, this system for Australia must meet some extra requests specific to Australia and New Zealand projects, like the cable laying rules, the distances between each stair and etc. GN Solids Control has an engineer team with rich experiences and a strict QC department to survey the producing procedure and final products, that’s why clients are always happy with GN. In the past years, GN has provided to Australia and New Zealand many systems, including but not limited to following typical ones:

1. Webster drilling’s solids control system, which was fabricated by GN Solids Control years ago.

2. A helicopter lifting system with accurately calculated weights for each tank unit.

3. A 400BBL system with 2 mud tanks and 1 mixing hopper skid with limited height and minimum storage capacity.

And in HDD industry, GN Solids Control has delivered more than 30 sets of complete mud systems to Australia and GN Solids Control is the most famous Chinese brands, and one of the best known among international brands.
Shaker screen is another popular product GN provides to Australian market. Last year when GN upgraded the screen producing line and started to make all frame screens with composite material frames.

On the bottom of mixing tank in a complete drilling mud solids control system, there are always 2 sets of centrifugal pumps installed there. These 2 centrifugal pumps are parallel connected, by means of complicated valves and pipes, these so called mixing pumps could serve for various functions more than mixing when connected with other equipments.

Here, we cited the 3 main functions of mixing pumps.

  1. Traditional function as mixing pumps when connected with mixing hoppers.

As the 2 centrifugal pumps are called mixing pumps, they are connected to 2 mixing hoppers installed on tank top. The inlets of centrifugal pumps are connected with pipelines leading to mixing tank, and next storage tank. Such pipelines are controlled by valves, and therefore, either centrifugal pump can be fed from either tank, and also could feed either hopper.

  1. As mud pump feeding pumps.

There is a bypass pipeline on outlet pipe of centrifugal pumps, when the valves to mud tank is shut down and valve to mud pump is open, the pumps could feed mud from mixing tank or storage tank to the mud pumps, via which, the well treated drilling mud could return to drilling system.

  1. As mud gun feeding pumps.20141101_102604

Another bypass pipeline on outlet pipe of centrifugal pumps are directed to mud gun pipeline on the cubic pipe by side of mud tanks. This pipe is used for feeding the mud guns. Mud guns are installed all over the tanks, except for the shaker tank. Besides stirring the mud from settling, mud gun and their pipes are also used to transfer drilling mud from tank to tank.

In a word, mixing centrifugal pumps and mixing systems are vital to a complete and efficient drilling mud solids control system, and GN Solids Control, as the TOP solids control system designer and manufacturer in China, is professional in such field, and always provides with customers the most suitable solutions and high quality products.

This weekend, GN team will attend to Abu Dhabi Oil Show held in UAE. You’re welcome to visit our booth in HALL 10, 10320D.

Mud Hopper Brief Indtrodcution

Mud hopper usually used in mud mixing pump, High shearing mixer. Or the mud hopper can be used as separated device matched with pump to do bentonite configuration and mixing in mud mixing system

Most popular mud hopper is 6 inch low pressure (435~580MPa) type. Mud hoppers Complete with 2 nozzle, venturi, funnel, sack table, 6 inch butterfly, valve all mounted on a base.

GN Mud Hopper VS FSI Hopper Feature

GN common mud hopper including 6”(150mm) and 4”(100mm) inlet diameter, the usual input whole dimension is designed as 600x600mm, or 750x750mm according to bentonite bags dimension.

Fluids system mud hopper well known by world clients. They hold strict standard also technique process. Including paint requirements. Anyhow, GN also pursue better hopper as ideal solution for client demand on mud mixing pump and slurry processing.

Commonly GN mud hopper with 2”(50mm), 1-1/2”(40mm), 1-2/5”(35mm). Also the mud hopper can be customized on the caliber dimension according to client actual requirements for the drilling mud processing or mixing.

Mud Hopper Work Condition

The mud hopper also be matched with centrifugal pumps (sand pumps), used on HDD, land drilling, and offshore drilling, etc. A butterfly valve is incorporated in the neck of the hopper to adjust flow and to close off the hopper after use.

The working condition of mud hopper usually is mud density 1.5~2.8g/cm3, while mud viscosity is 60~120s. This is usual working condition to provide better performance as well as longer use life to save total cost on drilling.
