Drilling fluid mud gas separator is a special equipment of gas cut drilling fluid primary degassing, it is mainly used to eliminate the bubbles which the diameter is about 3-25mm.

The big bubbles is aiming at the expansion gas which is fully the borehole, if it is not eliminated, it will causes the well kick even spurt the surface of drill plate. The equipment uses the prevent sulfur material and adapts the gas with H2s processing.


Installation and maintenance


It is installed ground side of the circulation tank, use steel wire ropes fixed gas liquid separator with the ground.


1Before using, we should check the bottom buffer baffle, if attrition more than 10mm, it must be replaced the two baffles at the same time.
2After using we should keep the separator empty and open the washing month and clean it.

DC Solid control is a professional manufacturer of solid control equipment. We can supply all kinds of mud gas separator such as DCZYQ800, DCZYQ1000, DCZYQ1200.

DC Solid control is a professional manufacturer of mud cleaning system. We transported a set of drilling liquid mud plant in batches to our customers on March 30, 2022. We provided integrated solutions and services for this liquid mud plant project from planning, construction to production and operation.


This liquid mud plant consists of mud agitator system, pipeline slurry transfer system, conveying system, solids control system, slurry mixing system, slurry storage system, electric control system and slurry laboratory.

First of all,the mud in the mud pit is stirred and cleaned through the mud agitator system, and transported to the solids control system for separation, then, it is mixed and prepared through the slurry mixing system through the conveying equipment and pipeline slurry transfer equipment, finally it is stored in the slurry storage system for use.


Our customer was very satisfied with the integration scheme and technical ability of our company in the field of drilling mud station construction and establish cooperation with us finally after in- depth investigation on the domestic drilling mud station at very beginning.

We sent our technical engineers to our customer’s project for on-site investigation to understand the project site in details. As required, we finally provided our customers with integrated solutions and services for the whole process from planning, construction to production and
operation. At the same time, we have established friendly and long-term cooperative relations.

Last week DC Solid control ship 4 sets of double deck shale shakers to abroad clients. Although effected by COVID, but DC machinery business was not affected. We obtained more and more foreign business.

Dual-deck shale shaker, also be called double layer screen shale shaker, is a fitful device on drilling mud management or HDD. It is linked to upper-and-lower two screens deck into one shale shaker. The upper deck is all for scalping, with API40 screens, and the lower deck is with API100 screens.

shale shaker

Selection of screen mesh for a particular application depends on a number of factors: flow rate, fluid condition, formation, rate of penetration (ROP), fluid type and number of shakers. The finest screen possible is to be used to ensure optimum performance to the relative screen life. However, coarser screens give higher capacity.

drilling fluid shale shaker

The screen cloth is considered to be one of the most important parts of a shale shaker and hence a good understanding of screen technology and its effects on shaker capacity are important.

Dual deck shale shaker use two different mesh screen. The top deck use coarse screen bring about scalping screen function.

Hookstrip bonding shaker screen is a kind of screen which is designed by our country proper development, it is made of two layers or three layers of stainless steel cloth to glue, it without metal plate, the screen cloth according high temperature bonding technology to strong unifies in together. This kind of multilayer structure design increases the strength of shaker screen and using life time. But each screen meshes are different, accurate and reasonable collocation make screening effect is more detailed, it not only can guarantee the enough strength but also increase the effective area in screening process.


Hookstrip soft bonding shaker screen use a coarse mesh screen and a detail mesh screen to bond together. When use it, we should install a network, then the bonding laminated screen is tension. Field tests show that, the using life of this kind of screen can extend. Special to point out, the two sides of super fine screen is not pressed in crochet, so in tension process, the more fine screen layer bears pressure is very small, it is only used as screening layer. This new kind of pressure layer is separate with screening layer is proved is reasonable and the effect is remarkable.

shaker screens

The crudeness or fineness of bonding grid size and bearing layer screen is according need to choose. The upper screen is more fine, the stress layer screen is more fine, the size of grid smaller. Usually the screening layer use 60-100mesh, the stress layer use 30 mesh, when screening layer is bigger than 150 mesh, the stress layer use 40mesh. When screening layer is bigger than 150mesh, the press layer use 60 mesh, in general the grid size is 33mm*25mm*25mm.

Desilter is the third class equipment in solids control system, it is used to separate the solid particles whose diameter is 15-44μm from drilling fluid. The desilter produced by DC Machinery has the advantages of large handling capacity, high separation ability and convenient operation.


The important problem is how to install it.

A The outlet and inlet connected by 6’’sebific duct, there is a pore on the top of overflow pipe to prevent desilter produce siphoning functionary. In order to don’t affect desilter regular work, we should not block the air-bleed hole, because it will have little drilling fluid outflow when desilter works, when it works shouldprevent desilter bleeder pipe blocked to avoid influence it normally work.
B The two ends of inlet pipe and overflow pipe all connected with flanged, and guarantee all can ingress or egress drilling fluid, in order to 8’’sebific duct caninstall in the other tank, the joint of overflow pipe can extend to any angles of axis spinning.

C Before operate desilter should open the screen box fixed device.
D The outlet pressure of centrifugal pump is the key of adjustment desilter.
E We must note when install screen, because screen installation directly influence screen service life, if can’t well install will damage screen. When install screen shouldn’t too loose and too tighten, if too loose, screen and supporting adhesive tape will have panting when shale shaker works, screen will rapidly damaged. If tootighten, screen forced too big can damage serious even tear the screen.
F Using retaining mechanism, it used to lock the screen and tighten scroll.
G We should notice the screen maintenance, don’t use spade and other hard scrape, hit screen, and according to different drilling fluid use different mesh screen.







Poorboy degasser also called mud gas separator that is an ideal for use where drilling is likely to encounter large volumes of gas. The technology is especially beneficial in sour gas environments or when drilling with an under balanced mud column.

To be as an professional producer of drilling fluid circulation equipment, DC Solid control has many different models of mud gas separator for sale, such as ZCQ800,ZCQ1000, and ZCQ1200. Different types with different treating capacity that according to your actual use to proposal.

Mud gas separator

Eachmud gas separator has limitation on much it can safely handle volume of gas. If the volume of gas exceeds the maximum limit, gas can blow through into the rig. It is very important that you must estimate gas flow rate on surface based on pit gain and kill rate in order to see how much expected gas on surface. This will be the limitation on how much you can circulate for well killing operation. You can estimate the volume gas on surface by using well control kill sheet provided by several companies. You need to ensure that the vent line should be as straight as possible with a larger ID in order to minimize back pressure while venting the gas out.


Anything that you don’t understand, please contact us to learn more about how to calculate the gas volume of your drill rig. And welcome to your valued inquiry of mud gas separators.
