HDD Mud Treatment System from DC Machinery

HDD Mud Treatment System is a set of specially developed equipment for non-excavation engineering, drilling fluid recycling (mud treatment system) is involved in separating the simple excavated spoil from the fluid/slurry, so it is not separating all solid matters, only separating the unnecessary matters.

Drilling mud tank design and manufacturer from China supplier

As the Mud Tank Manufacturer, DC Solid control can design and provide the different models Skid mounted tank, Mud Storage Tank, Mud Circulation Tank, Mud Recycling Tank, Mud Mixing Tank, Oil Sludge Tank for Oil drilling mud control system and HDD drilling Mud recycling system. Customized into horizontal mud tank, vertical mud tank and trailer mounted 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.

mud tank

The main function of mud tank is storage, because the worked drilling fluids must stored to the next separation or to the next recyclation, or to be reused. A tank is sectioned off into compartments. A compartment may include a settling tank, sometimes called a sand trap, to allow sand and other solids in the drilling fluid to precipitate before it flows into the next compartment. Other compartments may have agitators, which are large fan blades stirring the fluid to prevent its contents from precipitating.

Mud tanks play important role during solids control system. If any leakage please inspect all pipe fittings, connections and drain gate at once. Find out the reason as early as possible and do related repairing. If we can’t confirm the reason please contact DC freely we’ll give you solutions at soonest.

 

Cost-effective mud cleaner from DC Solid control for sale

Mud Cleaner is the second phase or the third phase solids control equipment, and it is the combination of desander, desilter and underneath shale shaker, so it can be called Desander and Desilter.

The mud cleaner can integrate a group of de-sanding cyclones and de-silting cyclones on one vibrating screen. The drilling fluid will firstly pass the de-sanding cyclones or de-silting cyclones for separation, with overflow returning to the circulatory system and the bottom flow screened and treated by the vibrating screen. If necessary, the vibrating screen of the integrator could be used as the fore-stage vibrating screen.

Oifield cleaners

The Mud cleaner  was used on many wells. In these applications, mud weights have ranged from 9.5 to 18.6 ppg. No well using the mud cleaner had a differential-pressure sticking problem. Many of the offset wells had experienced this problem, and the mud cleaner was used primarily to decrease the chance of getting stuck. The mud costs in these wells have varied above and blow the predicted costs.

The number of the desaner and desitler cones is customized to the drilling circulation system mud flow. And our shaker unit can easily fit in with the hyrocyclones assembly. Please contact us and our sales representative will give you an optimum solution for your system.

Centrifugal pump/feeding Pump China factory

Usually, oilfield centrifugal pump is a machine which converts mechanical energy into the kinetic energy of oilfield centrifugal pumped fluid for the purpose of transporting that fluid from one point to another.

But in order to be classified as a centrifugal pump, oilfield centrifugal pump needs to have two unique components: the first is a rotating disc with curved blade like vanes on it called an impeller, and the second is a specially shaped pipe called a volute casing which contains the impeller and the pumped fluid.

centrifugal pump

We have many model of the drilling fluid sand pump, the commonly used are SBSB8x6-14, SB6x5-12, SB5x4-12, SB4x3-12 and ect. Usually users selects the centrifugal pump is according to flow rate demand. Furthermore, the flow rate is related with motor power, head, electric system, the impeller size. Centrifugal pump in drilling mud process system is mainly power supply. And pump drilling fluid from mud tank to mud process equipment. Such as desander, desilter, or mud cleaner cones, decanter centrifuge.

sand pump

Besides, the pump working condition is rather hard by transferring drilling fluids with solid in for a long term. We need the bearing seal to be very reliable and steady. If you have request of any sand pump, please freely to contact DC Machinery.

Decanter Centrifuges in drilling mud cleaning system

Decanter Centrifuges are a key component in drilling mud cleaning on a Drilling Rig solids control equipment to the oilfield. To maintain drilling mud in an optimum condition results in less waste, reduced operating cost and a high efficiency of the total solids control system.

Separation point of decanter centrifuge is as fine as 2~7 microns. According to different rotation speed, there are high-speed and middle-speed centrifuges. It really plays an important role in lower mud density and bentonite recovery.
