Trial order of corrugated pyramid shaker screen from Nigeria

Trial order of pyramid shaker screen will flying to Nigeria this morning. This is only a simple which we send to them. The use of corrugated pyramid screens on a dryer in second stage mud and cuttings cleaning helped recover a large volume of oil-based drilling mud to save more than $60,000 in mud costs.


DC Machinery Company has again revolutionized screening technology with the introduction of the patented Pyramid (PMD) and Pyramid Plus (PMD+) screens. This revolutionary three dimensional screen design offers the benefits of traditional flat screens while adding a significant increase in useable screen area; allowing for a 70% increase in fluid handling capacity.


Benefits of Pyramid Screens compare with the flat screens:

1. Increased Shaker Capacity—Pyramid and Pyramid Plus screens increase the total amount of useable screen area by 50% to 125%.
2. Screen Finer Faster—Utilizing Pyramid or Pyramid Plus screens enables rigs to screen 2 to 3 mesh sizes finer than traditional perforated plate panels. This maximizes solids removal capacities.
3. Makes Fine Separations—Pyramid and Pyramid Plus screens are capable of making separations as fine as 43 microns.
4. Easily Repaired—The Pyramid screen design lends itself to easy field repair with RTV products.

Pyramid screens provide an easy, cost effective increase in shaker performance. Designed with the latest technology, Pyramid screens allow rigs to screen finer earlier in the drilling process, thus significantly reducing mud and disposal costs.

Lowestline price of mud guns from DC Machinery

Mud gun is another equipment for agitating drilling mud or fluid during mud process. It is mounted on mud tanks. DC Machinery 2 models of mud guns 2″ and 3″.

For many years, mud guns were used as the sole means of agitation. These devices usually carry mud from a down stream comapartment and spray it into an up-stream compartment to keep solids suspended. However, the true mixing effect of mud guns tends to be localized around the point where the nozzle may add 100-200 GPM of mud into the tank above and beyond the normal flow from the well.

Daily maintenance of DCZCQ vacuum degasser

DCZCQ advanced degassers are designed to remove virtually all entrained gases—including hydrogen sulfide and corrosive oxygen—from drilling fluids. These degassers reduce the threat of dangerous and costly blowouts caused by recirculating gas-cut mud.

The maintenance of vacuum degasser for drilling fluid processing in daily use is more important than the repair after it breaks down. So I’d like to introduce several tips about the maintenance.


Firstly, the vacuum degasser for drilling fluid processing should be washed after use. The rotor and the suction pipe in the vacuum tank should be cleaned. You should cut off the power supply, remove the blocking plate of the hole, and check components whether it is damage or not. You could wash the tank wall and the rotor by using high-pressure pipe. All the cleaning work should be done after each use to ensure the normal use.

Secondly, the top cover of vacuum tank should be cleaned once a week in order to avoid debris blocking the gas channel. When it is washed by water, you should rinse off the vacuum line and remove the screw plug and table seat. High pressure pipe is inserted into it for 3~5 minutes each time.

Thirdly, for the vacuum pump, you should always check working condition of bearing and lubrication condition. The bearing is 15~20 degrees higher than ambient temperature on normal working condition. When working temperature of vacuum degasser for drilling fluid processing is higher than 30 degrees, you should always check the vacuum gauge, replace water in separator of steam and water in time, and maintain the water temperature less than 35 degrees.

Drum and screw together of decanter centrifuges

Drum and screw together is the key part of decanter centrifuges. The screw of a decanter (solid wall screw centrifuge) serves to discharge the solid material from the drum and can, depending on the application, be performed differently.

Thus, in the event of abrasive media, various forms of wear protection can be added to the screw helix. Furthermore, for sanitary applications or for sticky products, the screw helix can, if necessary, be relief ground.


There are also different versions with respect to the gap of the screw helix (screw pitch) to each other and with respect to the number of screw flights.

In addition there are different designs with respect to the form and position of the holes or slits, through which the medium to be centrifuged is fed into the decanter drum.

DC Customized Mud Recycling System for HDD

Horizontal directional drilling short name is HDD. HDD technology has the obvious in oil and gas pipelines crossing the rivers, lakes, highway, railway hub and other obstacles and important area.

Relative to the use of drilling fluids within the oil &gas industry, the use of drilling fluids within the horizontal directional drilling (“HDD”) industry, is new. As the use of HDD technology did not become mainstream until the 1980’s, it took another decade before drillers started to consider the use of basic drilling fluids. Even today, the amount of research and development aimed at HDD drilling fluids is considered a rounding error in the oligopoly of drilling fluid manufacturers.



HDD Mud Recycling System is made up of drilling rig mouth to return to mud of the ground through the mud into the mud pit, using liquid slurry pump or vertical sand pump the submersible supply to shale shaker,and then male the shale shaker removing out of solid phased particles, the processed mud fall into the mud tank having many separate space.
