DC solid control equipment shipped to India at the end of July

Solids Control Equpment is used for maintain the drilling mud properties, Normally we call it 4 phases solids control equipment, including the first phase solids control control with the shale shaker for solids up of 100 microns, and secondary solids control desander for solids up 50 microns, and the thrid solids control desilter unit to remove solids above 20 microns, the fourth solids control decanting centrifuge to separate solids of 2-7 microns.

Many Models Of DCJBQ Series Mud Agitators for sale

Mud agitator operator, also known as drilling fluid agitator is used for mixing drilling fluid, making fluid particle float up to prevent them from deposition.

DCJBQ Series Mud Agitators have been designed keepingin mind the oilfield’s most severe mud mixing conditions at any weight. It’s rugged and sturdy design requires lower maintenance. DCJBQ Mud Agitators are highly energy efficient.

DCJBQ Mud Agitators have compact design and their low profile reduces headroom requirements providing more layout space on top of the tanks for other equipment. The low center of gravity ensures stability and safety should sudden shock loads be encountered by the Impeller.

DCJBQ Mud Agitators are available in four models ranging from 202kw to 15kw Horsepower. Impellers range from 20″ to 52″ and are available in foil, Canted, Flat or Turbine blade design. The Air-o-foil design promotes axial as well as radial flow and ensures all fluid is mixed continuously and the same fluid consistency is maintained in all parts of the tank.

The manufacturing ending work of desilters

Today, the desilter produced by DC Machinery already got the ending work, the desilter is used for building construction industry. Desilters are designed to remove silt-sized (20 to 74 microns) solids from drilling fluids.

Usually the cone diameter is less than 6″is called Desilter, and used as the third-control equipment in drilling operation. We commonly used 5 “and 4” cone to separate solid-phase particle size 15-47μm in the drilling fluid. Based on customer requirements and capacity, we can select groups of cone into Desilter.

The desilters are simple to operate and easy to maintain. Optional shutoff valves on each round desilter cone inlet permit individual cone removal and inspection without interrupting operation of the desilter.

Useful of mud desander for a active mud system

A desander is an important part of the mining and drilling process. This simple container helps filter out grainy solids from drilling liquid, often in mud form, that is brought up from a drilling hole.

Desander located close to the end of the entire purification process, but not the last step, desanding is renowned for its simplicity and lack of moving parts. Its effectiveness has seen this technique adapted into many industries.

Desander 1

Desanders are what larger diameter hydro-cyclones are typically referred as, and will be the next step in solids removal after an initial scalping shaker pass.

Desanders are capable of handling large flow rates, up to 500 gpm per cone, but do not offer as fine of a cut. The underflow will be recirculated over a shaker and processed again while the overflow will be free to move on to the next stage, typically a desilter.

Generally, colorfully named tools such as gas busters, gumbo removal equipment, shale shakers, mud cleaners and vacuum degassers are all used to break down the fluid to the stage where the desander can remove small grains. After the desander is utilized, many industries also use a desilter to further purify the liquid.

Why Choose Coarse Flow Line Shaker Screens in drilling rigs

Most drilling rigs operate their primary flow line shakers with screens that are far too coarse (to achieve meaningful solids control. Many factors cause this selection, and we now find ourselves in a viscous industrial cycle.

shaker screen

To cut costs, drilling rig operators use coarse screens that last longer and require significantly less personnel attention. Further, coarse screens minimize the risks of whole mud losses when drilling fluid circulation rates are high. However, the risk of whole mud losses would be significantly reduced, if a sufficient number of shakers, creating sufficient surface area, were installed.

By using coarse screens, drilling rig operators have become more reliant on solids control service companies to maintain the drilling fluid performance and ultimately the rig’s rate of penetration.

Most drilling rig hands do not understand that usually, the wetter the solids discharge from the flow line shakers, the higher quality solids cut is being achieved. This is especially the case when drilling through reactive hydrophilic soils.

What will making mud gas separator blow-through.

DCZYQ Mud gas separators are intended to sustain safety for high pressure wells. Our units are closed bottom skid mounted model designed around safety and precision. Uniquely designed baffles break up mud and gas which is then expelled by the gas vent line to the flare line.

mud-gas-separator

But what will cause the mud gas separator blow-through.

1. Friction pressure of the gas venting through the vent line exceeds the mud-leg hydrostatic pressure, resulting in evacuation of fluid from the separator. Friction pressure of the mud through the mud return line is considered negligible because of its short length.

2. Vessel ID is too small, causing insufficient retention time for the gas to separate efficiently from the mud. This situation is commonly called insufficient separator cut.

To estimate a peak gas flow rate properly, we must consider a “typical” kick. The typical kick will depend on the well location, depth, type size, and component ratios of influx. Kick data should be based on previous offset well data and should be a realistic worst-case gas kick.
