Drill solids are the main contaminant of all drilling fluids and therefore their control is of the utmost importance. There are 3 main ways of controlling solids:

• Dilution

• Mechanical removal

• Gravity Settling

I ever saw in the water well drilling site in Mongolia that they do not use any solids control equipments but only dig several mud pits, by this way, it is very low efficiency and Environmental Pollution.

Solids control system is a way for mechanical removal the drill solids. Mainly it includes screen devices & Centrifugal Separation Devices. Screen devices is the most important equipment called shale shaker. In the future of solids control system, shale shaker will become the only solids control equipment which will be used instead of desander, desilter, mud cleaner, decanter centrifuge by improvement of its design. At present, linear motion shale shaker is the most popular vibration mode shale shaker.

But the arrangement of vibration motor various by different shale shaker manufacturer. Sometimes it is vertical installed, sometimes it is horizontal installed, it doesnot mean that horizontal installed shale shaker must be balanced elliptical motion shale shaker, it might be linear motion shaker.

As a part of rig package, mud system is a separate but an essential part, the handling of drilling fluids can save huge cost of drilling. In the early oil industry open earthen pits were used as settling area to separate solids and mud thereby acting as a solids control equipment.

Now, with the stringent environmental regulations and high mud costs, the economics of an effective mud system come into consideration. Different solids control companies introduce zero-discharge systems, closed-loop systems, “quick move” technology, screening technology, disposal options etc. No reserve-mud pit is used in a truly closed mud system. Mud is continually processed primarily by mechanical means, such as screening, hydrocyclone and centrifuging to remove solids initially. A second stage to remove colloidal solids is by wastewater cleanup techniques.

Major components of a mud system, including:

Mud gas separator, flare ignition device

Shale shaker, mud cleaner(or desander, desilter), vacuum degasser, decanter centrifuge , centrifugal pump, mud hopper,  mud agitator, mud gun, mud tank and others, such as cutting dryer, screw auger, mud cooling unit,etc.

GNZYQ1000 mud gas separator is capable of handling 1000~1400gpm drilling fluids. We have 6 units of mud gas separator in stock which are all ready for shipment with painting &　package, welcome to contact with our sales. Except for mud gas separator, we also have flare ignition device in stock, which usually worked together with mud gas separator for oilfield. Mud gas separator is used to separate the harmful gas from the drilling mud, then flare ignition device is used to connect to the gas discharge line of mud gas separator, and burned it , they work together to avoid “kick” situation.

According to base type , the mud gas separator can be divided into :

• Fixed type
• Elevating type

According to the bracket type, it can be divided into horizontal type and vertical type. Most of Chinese mud gas separator is vertical installed, when you need to transport it, you can lay it down , and there is lifting pad hotizontally. MI-SWACO mud gas separator is horizontal type with a skid, it is for simplifies transport, spotting and installation. Unit can lay down during over-the-road transport
