Welcome to contact GN solids control if you are interested to apply for our distributors in Venezuela. GN solids control is a young but fast developing company and we are solids control specialist in China. We have exported many sets of drilling mud cleaning and recycling system to South American regions, for example, Brazil, Colombia, Venezuela, Argentina, Ecuador, etc.

Perhaps the most important thing to know about Venezuela is that it is an oil exporting country, the fifth largest in the world, with the largest reserves of conventional oil (light and heavy crude) in the western hemisphere and the largest reserves of non-conventional oil (extra-heavy crude) in the world.

GN manufacture complete line solids control equipments for the drilling rig( shale shaker, desander, desilter, mud cleaner, vacuum degasser, decanting centrifuge, mud pump, poor boy degasser, mud gun, mud agitator, mud mixer,mud tank), and we can provide a complete solution on drilling waste management( high G dryer, decanter centrifuge, screw pump, vertical cutting dryer, mud tank, etc). As government policy is more and more strict on environment related on drilling, our equipments are more and more important recently.

All of the foregoing sets the stage for showing just how extremely important the country’s conflict over oil is. At the most overt level, the conflict between the Chávez government and the oil industry is one about who controls PDVSA. Beyond that, the specific issues that control is being fought over have to do with the company’s efficiency, its internationalization program, its outsourcing and subcontracting practices, OPEC membership, and special oil contracts.

PDVSA, State owned company in Venezuela

PDVSA has a production capacity, including the strategic associations and operating agreements, of 4 million barrels per day (600,000 m³). Officials say production is around 3.3 million barrels per day (520,000 m³/d) although most secondary sources such as OPEC and the EIA put Venezuela’s output at least 500,000 barrels per day (79,000 m³/d) lower.

GN solids control exported several sets of drilling mud system to Amazon region, including Ecuador. We can produce the complete drilling mud separation system, including shale shaker, vacuum degasser, desander, desilter, decanter centrifuge, vertical cutting dryer, mud tank, etc.

 Ecuador produces more oil than it needs for domestic consumption and thus it is one of the country’s leading exports. Therefore, any new drilling for oil is not intended to meet local demand but is intended for export overseas, most likely to Japan and the United States.

Drilling mud is used to control subsurface pressures, lubricate the drill bit, stabilize the well bore, and carry the cuttings to the surface, among other functions. Mud is pumped from the surface through the hollow drill string, exits through nozzles in the drill bit, and returns to the surface through the annular space between the drill string and the walls of the hole.

Drilling mud separation system

As the drill bit grinds rocks into drill cuttings, these cuttings become entrained in the mud flow and are carried to the surface. In order to return the mud to the recirculating mud system and to make the solids easier to handle, the solids must be separated from the mud. The first step in separating the cuttings from the mud involves circulating the mixture of mud and cuttings over shale shakers.

The liquid mud passes through the screens and is recirculated back to the mud tanks from which mud is withdrawn for pumping downhole.

GN provides air-operated double-diaphragm pumps and accessories. Now we have inquiry for Air compressor driving the diaphragm pump. Welcome air compressor manufacturer to contact us for cooperation.

What is Air Diaphram pump?

An Air Diaphram pump is a positive displacement pump that uses a combination of the reciprocating action of a rubber, thermoplastic or teflon diaphragm and suitable non-return check valves to pump a fluid. Sometimes this type of pump is also called a membrane pump.

Air Diaphram pump features:

• have good suction lift characteristics, some are low pressure pumps with low flow rates; others are capable of higher flows rates, dependent on the effective working diameter of the diaphragm and its stroke length. They can handle sludges and slurries with a relatively high amount of grit and solid content.
• suitable for discharge pressure up to 1,200 bar
• have good dry running characteristics.
• are low-shear pumps.
• can be used to make artificial hearts.
• are used to make air pumps for the filters on small fish tanks.
• can be up to 97% efficient.
• have good self priming capabilities.
• can handle highly viscous liquids.
• are available for industrial, chemical and hygienic applications
• cause a pulsating flow that may cause water hammer

GN 2-WAY Flow Divider is designed to maximize the solids removal capabilities of shale shaker. It is mainly used for GNZS703 tandem shale shaker, GNZS852 triple shale shaker.

 Function of flow divider for LMSS

• Ensures even distribution of liquid and solids to downstream shakers
• Eliminates need for back tanks and shaker bypasses
• Minimizes the effect of pitch and heave

Solids removal efficiencies are dramatically increased by the Flow divider, which distributes fluids/solids equally to multiple downstream shale shakers. Positive sealing weir gates are removable, allowing flow per selected shaker or installed omitting flow. The Flow divider eliminates the need for back tanks and shaker bypasses and minimizes the effect of pitch and heave. The unit is available in four sizes: 2,3, 4, 5, and 6 way.

How do Derrick Flow divider Work?

Mud from the flow line enters the rear of the Flow divider (1) where it contacts a baffle (2) allowing the flow to pass under and sometimes over before it flows over the weirs (3), and divides the liquid and solids equally between the desired number of shaker feed ports (4). Positive-sealing weir gates permit flow to the downstream shakers .

GN Flo-divider advantages

1 Eliminates the need for a back tank and shaker by-pass

2 Minimize the effect of pitch and heave

3 Reduce overall space requirement

4 Fit easily onto most rigs

5  It is applicable for all GN shakers
