If you're new here, you may want to subscribe to my RSS feed. Thanks for visiting! GNZS703 shale shaker produced by GN solids control has been widely used in oil & gas drilling. GNZS853 shale shaker is normally used for drilling cuttings treatment.
Below is the photo taken in South America oilfield drilling site. They use GN shale shaker to separate the large solids from the drilling fluids and get clean mud for reuse. Also they user GN shale shaker as a underflow shaker to help the performance of desander cone & desilter cone.
 shale shaker for sale To know how to operate GN shale shaker is much more important, also the maintenance. Only if you operate and maintain it according to the manual, you will use it same with Derrick, SWACO shale shakers.
1 Angle adjustment
The angle can be adjusted both under running and off condition.When delivered ,the deck is horizontal(0°) 。While operating with the same shaker screen, according to the worksite mud property, and feeding capacity ,by adjusting the deck angle in order to improve the treatment result .When the drilling mud run off, enlarge the deck angle to solve the problem. Angle adjustment range -1°~+5°，rated angle 0°~3°。
2 Pool configuration
A better pool configuration can maximize the screen area and such achieve better result. It is hard to set the deck angle at one time ,it needs the operation personnel adjusting several times according to the flow of the mud .The best pool configuration is when the mud covers the first and second shaker screen.
3 Screen tention

Drilling fluid is used to aid the drilling of boreholes into the earth. Often used while drilling oil and natural gas wells and on exploration drilling rigs, drilling fluids are also used for much simpler boreholes, such as water wells. Liquid drilling fluid is often called drilling mud.
In drilling operations, solid weighting materials are commonly added to the drilling fluid to give sufficient density to the fluid to hinder inflow of oil or gas into the wellbore from the down-hole formation. Weighting material sag. i.e. sedimentation of weighting material from the drilling fluid, has been and is currently one of the biggest challenges within the drilling fluids industry as it can lead to well control problems, lost circulation, hindered running of casing/liner, insufficient displacement etc.
 weighting material adding equipment CALCIUM CARBONATE is Acid souble weight material.It is used to prevent fluid invasion of permeable zones, and to prevent loss of circulation during drilling, workover, and completion activities. CALCIUM CARBONATE is applicable in all drilling fluids, aqueous and non-aqueous. It can be used to prepare a pill for spotting purposes. is also used as an acid soluble weighting material for drill-in or workover fluids with a density of 14.0 ppg or less.
HEMATITE is for extremely high density mud.It is used to obtain mud weights in excess of 20.0 ppg in water based drilling fluids, 19.0 ppg in oil based drilling fluids, or any time that exceptional control is required of solids percentage for rheology control.
Barite is the most used weighting material, has a density of 4.1. It is used for increasing the density of fresh water, salt water, and oil based muds.
Barite is added through a hopper, GN designed Jet mud mixer is used for barite adding, it consist of venturi hopper and mixing pump. It can be used with the complete mud system, also it can be used separately.
Jet shearing unit is consist of venturi hopper and shearing pump, which can cut the big section into small pieces and add weighting material then mix them. It is commonly used in oil & gas drilling solids control system, usually it is installed on the weighting tank or mixing tank. Sometimes it is used together with decanter centrifuge.

When water-based muds (WBMs) were used, only limited environmental harm was likely to occur, but when operators employed oil-based muds (OBMs) on deeper sections of wells, the resulting cuttings piles created impaired zones beneath and adjacent to the platforms. So it is necessary to process drilling waste by GN drilling waste management system.
 offshore drilling waste manaegement Many offshore rigs do not process the drilling waste or even drilling mud at site, because there are professional facilities who can recycle the drilling mud and process the drilling waste. Then the rig can re-use the recycled drilling mud. Unlike onshore drilling rigs, there are complete solids control systems in onshore drilling site.
The drilling waste produced by onshore drilling are mainly drilling cuttings and less water, which can be transferred by screw conveyor to hi-G shaker or vertical cutting dryer for further process.
The drilling waste produced by offshore drilling usually is not produced by solids control equipments, they are collected by containers then transport to the drilling waste management facilities for process. Firstly they are pumped to shale shaker( drying shaker), then desander, desilter cone, the clean fluids can be processed by decanter centrifuge directly. The cuttings are transferred to vertical cutting dryer, then to decanter centrifuge, the clean fluids are collected and re-used in offshore drilling rig.

The majority of Mud Motor use is in the drilling of Directional Holes. Many of our HDD contractor clients asked if we have mud motor for sale, they prefer a complete solution for triplex mud pump, mud motor, recycler, mixing unit, GN can provide mud recycler and mixing unit as a package.
 HDD mud motor recycler Mud motor also called Drilling Motor refers to a Progressive Cavity Positive Displacement Pump placed in the Drill string to provide additional power to the bit while drilling. The PCPD Pump uses Drilling Fluid to create eccentric motion in the power section of the motor which is transferred as concentric power to the drill bit. The Mud Motor uses different rotor and stator configurations to provide optimum performance for the desired drilling operation, typically increasing the number of lobes and length of power assembly for greater horsepower. In certain applications, compressed air, or other gas, can be used for Mud Motor input power. Normal rotation of the bit while using a Mud Motor can be from 60 rpm, to over 100 rpm.
GN mud recycler and mixing unit can match with Ditch Witch HDD rig and Vermeer rig according to their required mud flow capacity. The recycled drilling fluids by GN mud recycler and mixing unit are provided to mud motor for charging.
Mud motors are powered by drilling fluid ,the fluid consists of water mixed with bentonite or polymer additives designed to match various soil conditions. The fluid is pumped down through the drill string to the downhole motor, which converts the flow to rotary speed and torque.

GN solids control is specialist of solids control equipments for rotary rig in China, we have various kinds of mud equipments in stock, welcome to inquiry us.
Rotary rigs drill the vast majority of wells today, including all medium and deep wells. The rotary rig consists of four major systems. These include the engines, and the hoisting, rotating, and mud systems.
 rotary rig equipments General of drilling mud(drilling fluids)
Common drilling mud is made of bentonite clay. A heavier drilling mud can be made by adding barite. Various chemicals are also used in different situations. The drilling mud liquid is usually water but is sometimes oil-based. Drilling mud are described by weight. Water weighs 8.3 pounds per gallon. Average bentonite drilling mud weighs from 9 to 10 ppg. Heavy drilling mud weighs from 15 to 20 pounds per gallon. The heavier the drilling mud, the greater the pressure it exerts on the bottom of the well.
Fluid is circulated while the drilling proceeds. Powerful pumps move the fluid down to the pipe, through the bit and back to the surface, carrying the cuttings and other debris with it. Thus, on a rotary rig , drilling can be continuous as stopping to bail the cuttings is no longer required. The drilling mud also stabilizes the walls of the hole.
Mud circulation system for rotary rig
Drilling mud is stored in steel mud pits beside the rig. The drilling mud then flows down through the hollow rotating drill string and jets out through holes in the drilling bit on the bottom of the well. The drilling mud picks cuttings from the bottom of the well. It flows up the well in the space between the rotating drill string and well walls.

Mud rotary drilling is popular in wellbore drilling, offshore works, well drilling, Horizontal directly drilling, mining, geotechnical. Drilling fluid system is one very important part of the drilling work. The two main parts of the drilling fluid system is the actual drilling fluid and the solids control equipments, to separate the cuttings from the drilling mud at the surface, and circulating water based drilling fluid.
 
As we all know the quality and charactor of the drilling fluid effects the drilling works. The viscosity, density, fluid loss control, sand content, gel strength, and so on. The drilling fluid system is used to control them.
If not use the drilling fluid system correctly, effiently, there must be some trouble. High fluid density causes pressure in the formation of the borehole. This pressure drives the drilling fluid through the filter cake into the formation, leads to excessive drilling fluid loss to the formation, and extends well development time required to remove the mud from the formation. As the fluid density increases, the pressure required to move the fluid up the borehole also increases, leading to high mud pump pressure requirements. Continue reading »

Centrifugal pump with mechanical seal some are required by GN Solids Control Clients for drilling mud System.As a manufacturer for mechanical seal centrifugal pump we give explanation info. as below.
Centrifugal Pump
A centrifugal pump is a roto dynamic pump that uses a rotating impeller to increase the pressure of a fluid. Centrifugal pumps are commonly used to move liquids through a piping system. The fluid enters the pump impeller along or near to the rotating axis and is accelerated by the impeller, flowing radially outward into a diffuser or volute chamber (casing), from where it exits into the downstream piping system. Centrifugal pumps are used for large discharge through smaller heads.
 Centrifugal Pump With Mecheanical Seal In some situations, packing material is not adequate for sealing a centrifugal pumps shaft. One common alternative method for sealing the shaft is with mechanical seals. 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.
The most effective method of preventing the leakage of the drilling fluids from the centrifugal pump to the external surroundings is using the mechanical seals. The mechanical seals Continue reading »
