Working principle and characteristics of single screw pump

Single screw pumps have been widely used in developed countries, and most foreign countries call single screw pumps “Monopumps” (MONOPUMPS). Due to its excellent performance, the scope of applications has also been rapidly expanding in recent years. The biggest feature of the pump is strong adaptability to the medium, stable flow, small pressure pulsation, and high self-priming ability, which cannot be replaced by any other pump type.

The single screw pump is a new type of pump that works according to the principle of revolving meshing volumetric type. The main working parts are eccentric screw (rotor) and fixed bushing (stator). Due to the special geometric shapes of the two parts, separate sealed cavities are formed respectively. The medium flows uniformly in the axial direction, the internal flow rate is low, the volume remains unchanged, and the pressure is stable, so there is no vortex and agitation. The output pressure of each stage pump is 0.6MPa, the head is 60m (clear water), and the self-priming height is generally above 6m.

The transmission can be directly driven by a coupling, or variable speed by high-speed motors, V-belts, gearboxes and other devices. G type screw pump has few parts, compact structure, small size, simple maintenance, rotor and stator are the vulnerable parts of the pump, simple structure, easy to assemble and disassemble. Because the stator is made of a variety of elastic materials, this kind of pump has the advantage of conveying high-viscosity fluids and conveying media containing hard suspended particles or media containing fibers that cannot be matched by general pumps. Its flow rate is proportional to the speed.

Reuse of liquid and solid phases after treatment of waste drilling fluid

The drilling industry strictly follows the Environmental Protection Law and regulations regarding waste treatment, and it clearly states that the arbitrary discharge of waste from drilling and completion operations is strictly restricted. So in the process of drilling, we will have some questions, how to deal with the final waste? Where is it used in the end? KOSUN Environmental Protection provides solutions for drilling waste treatment!

The waste drilling fluid treatment system includes: drying shale shaker, screw pump, drill cuttings drying centrifuge, screw conveyor, and other solids control equipment that can be used for mud drying treatment. Among them, the drill cuttings drying centrifuge is the core equipment. We know that in the process of oil exploration and production, the waste will be left on the well site. These wastes are stored in the sewage pond of the well site. If the drilling waste is not treated thoroughly, it may pollute the groundwater and surface water and endanger the surrounding ecological environment.

In the process of waste drilling fluid treatment, it is processed from the source through solid control equipment-dehydration / water treatment / water recycling / filtration-mud recovery-solidification / biodegradation / thermal analysis / drilling cuttings reinjection four major steps. It reduces waste discharge, improves efficiency, and saves a lot of drilling costs. At the same time, in the reprocessing of waste, the dehydration treatment plan is fully utilized, which not only effectively recycles water resources, reduces the water content of discharged waste, reduces the volume of waste, and effectively protects the environment. Finally, the remaining solid wastes are effectively discharged through technologies such as solidification, thermal analysis, and drill cuttings reinjection. At the same time, the solidification treatment is used on land to realize the actual needs of drilling cuttings reinjection on the sea, with strong practicability and high efficiency.

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.

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.
