Shale shakers process drilling fluid and remove most of the large particles. The efficiency of operation of other solids separation equipment depends heavily on the proper and effective functioning of the shale shaker. Dual deck shakers are had tremendous advantage on the field of generate dryer cuttings and decease none- productive time.

The Screens of dual deck 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.

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 differnet mesh screen. The top deck use coarse screen bring about scalping screen function.

Many Models Of Shale Shaker From China DC Solid Control

These shale shaker devices remove drill cuttings from the drilling fluid while circulating and drilling. There are many different designs of the Shale Shaker and much research has gone into these designs to facilitate lowering costs associated with drilling fluid and drilling operations.

The basic design consists of large, flat sheets of wire mesh screens or sieves of various mesh sizes that shake or vibrate the drill cuttings across and off of thescreens as the drilling fluid flows through them and back into the drilling fluid processing system, often called the mud system. This separates the drill cuttings, often called solids from the drilling fluid so that it can be recirculated back down the well bore. In oilfield industry, linear motion type shale shakers are the standards foruse in drilling mud solids control systems in oil and gas well drilling.

Finished The Production Of The Decanter Centrifuge Mud Tank

A mud tank is a sizable storage container, typically with an open top. In the past, people called it a mud pit because it used to be just a pit dug out of the earth. It’s used to hold drilling mud.Mud tanks are constructed from welded-up steel plates and tubes. The bottom of the tank can either be square or cone-shaped. A tank can have several compartments.

tanks

DC Solid control finished the production of the decanter centrifuge mud tank for a China client Which is used for oil and gas industry. A mud tank is classified as either active or reserve. For safety reasons, a catwalk with guard rails may be installed at the top of the container. This allows workers to inspect the drilling fluid without the danger of falling into it.

mud tank

DC Mud Tank is divided into Square tank and Cone-shaped tank according to the shape of tank bottom. The tank body is welded by steel plate and section steel, either flat cone-shape structure or the corrugated structure. We choose steel grating or checkered steel which resistant to slip as mud tank covering, cat walk, and stairs.
On top of the tank, water pipelines are integrated for tank cleaning. The ladder includes the channel steel as the supporting and the linearity netted steel plate as the foot board. Hand rails are installed to safe suspension hook at both sides. The tank surface is coated with marine corrosion-resistant zinc rich epoxy coating and painting, generally two layers for tank inside surface and three layers for tank outside surface.

Each project is different, that is why we do NOT apply one-fit-all approach. We would analyse the project requirement and give the tailor designed proposal. From equipment configuration, tank design to electric control system, we always deliver the most satisfaction to our clients.

Characteristics and application of Hydrocyclone desander

Hydrocyclone desgassing technology is widely used in solid phase separation of environmental protection, medicine, food and other industries. The particle proves that hydrocyclone degasser is a kind of economic and efficiency, operation is simple and need not maintenance, it is a green and protection environmental physics water treatment equipment.

desander01

Hydrocyclone desander is according ministry of construction stander and allas stander is based on many practical, degassing effect is more ideal.
According the theory of centrifugal sedimentation and density difference, when water fluid is tangential enter into equipment from desander inlet by a certain pressure will produce strong spiral motion. Because the density of sand and water is different and in the function of centrifugal force, entad buoyancy, fluid drag force make the low density pure water rise is discharged from overflow mouth.

Desander and Tank Ready to Export to Malaysia02

The big density sand subside to bottom and discharged from degassing mouth to reach the aim of degassing. In a certain rang and condition, the salt of inlet pressure of desander is more big, the degassing efficiency is more high and it can many sets are parallel used.

Characteristics and application
The structure is simple, cost is lower, it is easy to maintain and operate.
The volume is small, capacity is big and save field space compared with expansion pipe, buffer box and other degassing equipment.

Application range: river water, well water degassing, solid and liquid separation and liquid eliminate gas.
Application area: it can be used in air condition water treatment, chemical, oil, mine, medicine and spin industries.

Drilling fluid centrifugal pump function and features

Drilling fluid centrifugal pump is a ideal corollary equipment which provide power for desander, desilter and the jet mud mixer, it also be as the replenishment pump of slurry pump. The most of components can interchange, it has the advantages of operation and maintenance is convenience, the leakage of the shaft seal is small, the
working operation is reasonable, the using lifetime is long. Because there are a lot of solid phase particles and all kinds of chemical additive in drilling fluid, so the impellers of centrifugal pump and the shell must meet the requirements of the two phases motion law, in order to decrease the wear, resistance the corrosion.

centrifugal pumps

The features of drilling fluid centrifugal pump

Now the centrifugal pump is in the oilfield, usually use the water parameter design, so the performance of the pump is influenced by the solid phase particles, density and consistence of drilling fluid. The abrasive of solid phase is accelerating the abrasion and the seal of the fluid passageway, made the performance of pump is decrease, using life is short.

sand pump

Drilling fluid centrifugal pump functions

The centrifugal pump is designed by the motion law of the two phases and the pressure change rules, according the best industrial and mining parameters of the experiment pump, make it fit the motion rules of the two phases in the pump. The types of the impeller is the half open, the number of the impeller is less, the radial of impeller is small, the length of the impeller is big, the inlet angle of impeller is big, the exit angle of impeller is small, the molded lines of impeller is logarithmic spiral line, in order to prove its indrawing and the abrasive resistance is good, the efficiency is higher than circular arc line blade 6% – 10%.

The volute chamber of centrifugal pump use the quasi spiral, the volute chamber section is rectangle. In order to prove it has a good waterpower and abrasive resistance. The shaft extension of centrifugal pump is short, the rigidity is good, arc is bracket, visuality is good, it has sense of beauty.
