GN mud mixing hopper are widely used in HDD(horizontal directional drilling) and oil gas drilling for bentonite mixing.Mud Mixing unit is combination of drilling mud hopper and centrifugal pumps,it’s mixing force comes from the centrifugal pump.

The mud mixing hopper, also called a jet mixing hopper, in which materials are put into the circulating mud system. The mud hopper is powered by a centrifugal pump that flows the mud at high velocity through a venturi nozzle (jet) below the conical-shaped hopper. Dry materials are added through the mud hopper to provide dispersion, rapid hydration and uniform mixing. Liquids are sometimes fed into the mud by a hose placed in the hopper.

Mud Mixing Hoppers

The GN Mud equipmet range of mud mixing hoppers delivers safe, accurate and reliable mud mixing for both on- and off-shore applications. Design of the hopper is focused on key safety and usability features such as dust-free operations, interfacing abilities and remote or manual control options.

The mud mixing unit can be delivered with an integrated Venturi-type mud mixer to provide fast, easier and more effective mixing of fluids and powders. We can also design and manufacture upgrades of existing mud mixing hopper systems to ensure dust-free operations and more modern interfacing abilities. Feeding and dosing is controlled using Open / Close valves; the valves can be controlled remotely (optional) or locally.

HDD mud desander is a hycdrocyclone desander separator used in Horizontal directional drilling mud system.

GN design and manufacture mud desander for HDD mud system and oil gas drilling.

HDD( Horizontal directional drilling)

Directional drilling (or slant drilling) is the practice of drilling non-vertical wells. It can be broken down into three main groups: Oilfield Directional Drilling, Utility Installation Directional Drilling ( or HDD., Horizontal Directional Drilling, Directional boring) and in-seam directional drilling (Coal-Bed methane).All of the HDD need mud system.and many of them needs mud desanders to be mounted on the mud tank.

What is a mud desander?

Usually  the cone  diameter is more than 6″is called Desander, and used as the second-control equipment in drilling operation. We commonly used 10 “and 12” cones desander to separate solid-phase particle size 47-76μm in the drilling mud.

A mud desander is a  hydrocyclone device that removes large drill solids from the whole mud system. The desander should be located downstream of the shale shakers and vacuum mud degassers, but before the desilters or mud cleaners. A volume of mud is pumped into the wide upper section of the hydrocylone at an angle roughly tangent to its circumference. As the mud flows around and gradually down the inside of the cone shape, solids are separated from the liquid by centrifugal forces. The solids continue around and down until they exit the bottom of the hydrocyclone fluids desander (along with small amounts of liquid) and are discarded. The cleaner and lighter density liquid mud travels up through a vortex in the center of the hydrocyclone, exits through piping at the top of the hydrocyclone and is then routed to the mud tanks and the next mud-cleaning device, usually a desilter. Various size desander and desilter cones are functionally identical, with the size of the cone determining the size of particles the device removes from the mud system.

GN oilfield flare ignitor system is also called Electric Ignition Device.The flare ignitor used for igniting gases from mud gas separator.

An Flare ignition system for flares is described particularly suitable for use in remote areas with limited facilities and which includes as components a power source and specifically storage batteries with a solar battery for recharging and having an associated gasoline engine driven blower for supplying air for ignition, together with an ignition panel

adapted for ready connection to a source of fuel gas, to the blower, to the power source, to the stack pilot, to the pilot ignitor and if desired to the flare header for purge gas supply. The panel preferably includes a manually oprable push button for an ignition spark plug, has indicators of pilot operation and has manual control of the delivery of fuel gas for ignition, for use as pilot gas and for use as purge gas. A thermocouple is provided at the pilot for control of indicating lamps indicative of pilot operation or non-operation as well as purge failure.

Flare Ignitor is also called oilfield torch unit.

Flare Ignitors ffshore exploration and well testing. Our models are available in 12 volt solar or 110 volt electric, each comes with a standard manual flame detection, and if requested can be fitted with a thermocouple for detection and monitoring.

Both horizontal sand pump and vertical sand pumps are used in HDD(horizontal directional drilling) and oil gas drilling fluids system.

• Horizontal sand pumps

Horizontal sand pump is an important equipment in oil rig mud cycling system, be able to deliver corrodive drilling fluid(with suspended particulates) or other liquid media under similar work condition, are the best optional pumos of sand removers, mud recovers and mixing hoppers as well as perfect perfusion pumps of mud pumps. For design of their parameters, that equipment with which such pumps are used together can operate under the best work condition has been fully considered. These pumps are mainly characterized by good versatility and exchangeability of parts, less leakage of shaft seal, reliable operation, long service life and convenient maintenance.

Horizontal sand pump are used for feeding drilling fluids mud cleaners,mud desander,desilters.And provide the force for particle separation of drilling fluids.

• Vertical Sand pump Application Instruction

Vetical sand pump in drilling mud circulation system is usually submersible pump,it usually used to feed drilling mud decanter centrifuge,and sometimes also used to feed mud cleaners,desanders,desiters. Continue reading “Horizontal & Vertical Sand Pumps for drilling fluids”

Drilling mud vacuum tank degasser is one type of degasser in oil gas drilling fluids system.Another type of degasser is called Atmospheric Degasser.

Both of the vacuum degasser are devices that removes air or gases (methane, H2S, CO2 and others) from drilling fluids. There are two generic types that work by both expanding the size of the gas bubbles entrained in the mud (by pulling a vacuum on the mud) and by increasing the surface area available to the mud so that bubbles escape (through the use of various cascading baffle plates). If the gas content in the mud is high, a mud gas separator or “poor boy degasser” is used, because it has a higher capacity than standard degassers and routes the evolved gases away from the rig to a flaring area complete with an ignition source.

Vacuum Tank Degasser

Vacuum Type is the most common form of degasser. It can be horizontal, vertical or round vessel. A vacuum action is created to pull in the gas cut mud. When the liquid enters the tank it will flow and be distributed to a layer of internal baffle plates designed for the mud to flow in thin laminar film and is exposed to a vacuum that forces the gas to escape and break out of the mud.The vacuum pump moves the escaping gas from the vessel discharging it to the rig’s flare or environmental control system.
