Drilling fluid centrifuge is a very important solid phase control equipment

In the drilling solids control system, the drilling fluid centrifuge is a very important solids control equipment. The drilling fluid centrifuge uses the principle of centrifugal sedimentation and separation to separate the suspension in the drilling fluid. It is one of the important equipment in the drilling field to balance the viscosity and specific gravity of the drilling fluid and recover the heavy gold powder in the drilling fluid. KOSUN horizontal spiral unloading sedimentation centrifuge is used for the separation of suspensions containing solid particles with a diameter of ≥2μm, as well as the treatment of drilling mud and liquid. It is particularly effective for oilfield and industrial services, especially in environmentally sensitive areas. The recovery rate is high, the solid phase control is effective, and the cost of mud replenishment and treatment is significantly reduced. This series of centrifuges are equipped with sophisticated dynamic balancing equipment, which can run smoothly for a long time at a speed of 0~3900RPM, and the centrifugal force generated can be as high as 3000G.

The drilling fluid centrifuge is a special equipment for solid-liquid separation. The separation process of the solid and liquid phases in the mud is completed in the drum, and is used to separate the ultrafine solid particles in the drilling fluid. Principle: The drilling fluid centrifuge uses the high-speed rotation of the drum to drive the mud that enters the drum to rotate at a high speed. The mud is thrown on the wall of the drum to form a liquid circle. The solid particles in the liquid circle are hundreds or even thousands of times greater than their own gravity. With the centrifugal force, the drilling fluid centrifuge overcomes the resistance of the mud viscosity and quickly settles on the inner wall of the drum to form a solid phase layer, and the liquid forms a liquid phase layer. The ratio of the centrifugal force of the solid particles in the fluid circle of the drilling centrifuge to its own gravity is called the separation factor of the centrifuge. A centrifuge with a large separation factor can separate finer particles from the mud.

Drill cuttings dryers are used in oil-based mud treatment system

Drill cuttings dryer is also called mud dryer, which is a kind of centrifuge. The spin dryer is a centrifugal separator that uses centrifugal filtration to separate the components in the suspension. There are many holes on the wall of the rotary drum of the drill cuttings dryer, and the inner surface of the rotary drum is covered with a filter medium. The suspension added to the drum rotates with the drum to generate a large centrifugal pressure. Under the action of the pressure, the liquid in the suspension flows through the filter medium and the holes on the drum wall and is thrown out, and the solids are trapped on the surface of the filter medium. Realize the separation of solid and liquid. The centrifugal force generated by the suspension in the drum is thousands of times that of gravity, which strengthens the filtration process, speeds up the filtration, and obtains a filter residue with a lower moisture content. Suspensions with solid particles larger than 0.03 mm can generally be used with drill cuttings dryers.

Drill cuttings dryers have been widely used in oil-based mud treatment systems:

1. Efficient solid-liquid separation, reducing solid phase emissions;

2. The liquid phase can be recycled and reused in the drilling solids control system;

3. Reduce drilling fluid costs and waste disposal costs;

4. Realize the on-site operation requirements that the mud does not fall to the ground;

5. Easy and fast to use, long time to use, which can effectively reduce product cost.

Oilfield Drilling Waste Mud Treatment Equipment
Oilfield Drilling Waste Mud Treatment Equipment

There are many kinds of Oilfield Drilling Waste Mud Treatment Equipment in oilfield drilling. Each treatment plan needs to be determined according to the drilling site and drilling construction conditions. It must not only achieve the treatment effect, but also meet the national environmental protection requirements, and strive to achieve harmless treatment. It plays an active role in improving and protecting the environment, soil and groundwater.

Drilling waste mud is one of the main pollution sources in the oil and gas industry, and its waste treatment is currently a major problem that plagues oil fields. The Oilfield Drilling Waste Mud Treatment Equipment is to treat waste drilling mud (drill cuttings) immediately while drilling, meeting the requirement of “mud not landing”, reducing land use and environmental pollution.

Oilfield Drilling Waste Mud Treatment Equipment is to change “end treatment” to “full process control”. The waste mud is diluted-flocculated-separated into three parts: rock cuttings, mud cake and water, and the solids in the mud are separated by washing and flocculation. With chemical reaction treatment, the cuttings and mud cakes can reach the discharge standard. After the harmful substances and chloride ions in the mud are separated into the water, they are then dehydrated by vacuum adsorption or extrusion to make mud cakes. At the same time, the mud cakes are separated by centrifugation. The wastewater is concentrated by air flotation sedimentation, filtration system, and reverse osmosis system. After treatment, the up-to-standard wastewater can be reused for drilling recycling.

Introduction to Mud Agitator and Reference for Selection

The Mud Agitator is an efficient mud mixing machine. Through customized size and configuration, it can meet the requirements of different types of mud tanks. How to choose a suitable model reasonably has become an important factor that technicians have to consider when designing.

The Mud Agitator is fixedly installed on the top of the mud tank, and the stirring rod impeller sinks into the mud. The stirring shaft and the motor are connected through a coupling, and the rated power is from 7.5 hp to 20 hp (5.5kw ~ 15kw). The selection of agitator should consider tank size, depth, and mud parameters. Generally speaking, single-layer impellers are used below 11kw, and double-layer impellers for 11kw and above. It depends on the depth of the slurry tank used on site or customer requirements.

The impeller of the Mud Agitator is fixed on the shaft by bolts to prevent the impeller from rotating and shaking during the mixing process. Normally, the impeller is installed at a height 3/4 times the diameter of the impeller from the bottom of the tank. For example, if the diameter of the impeller is 600mm, the impeller needs to be installed at a height of 450mm from the bottom of the tank. Guanneng Company recommends the use of a vertical impeller when the tank height is less than 1500mm, and an inclined impeller when the tank height is deeper. If a double-layer impeller is used, the vertical impeller is installed at the bottom, and the inclined impeller needs to be installed at 2/3 of the height of the tank bottom.
