Why is oil sludge sand classified as hazardous waste?

The structural characteristics of oil mud sand in the oil field are particularly complex and diverse, making it very difficult to handle. It is generally composed of structures such as oil-in-water, water-in-oil and suspended solid impurities, and is an extremely stable mixture. The oil components in the sludge sand mainly contain saturated hydrocarbons and aromatic hydrocarbons, and the content of colloid and bitumen is less.

The composition of oil mud sand depends on the geological conditions of the major oil fields, the production technology and the process flow, and is also directly related to the variety of chemicals added, the quality of sewage, and sewage channels. Generally, the moisture content and salt content The amount of ingredients is high. Most of the sludge sands contain harmful substances such as arsenic, mercury, and salts. The characteristics of oily mud sand are mainly high crude oil content, some of which have oil content as high as 50%, high cohesion, and the main binding component of oily mud sand is also crude oil. Oil mud sand dispersed in water will be naturally divided into crude oil floating on the water surface and sand particles sinking to the bottom due to gravity, which mainly depends on the larger component density of oil mud sand. In water, the density of crude oil is lower than that of water.

There is also a big difference in the properties of the old oily sludge sand and the newly produced oily mud sand. The old oily mud sand has a long storage time, so there will be light components diffused during the long-term storage process, while some crude oil is due to the separation of seepage. The physical and chemical reactions of oil sludge will greatly change the properties of oil sludge, and therefore will slowly transform into a mixture of heavy oil, asphaltene, sand and soil.

Based on the above-mentioned structural characteristics, components and properties of oily sludge sand in the oil field, it is explained that the harmful components of oily sludge sand in the oil field are more and more complex, especially in the process of oil production, the addition of various chemicals will increase the toxic components of the oil sludge. These toxic components not only increase the difficulty of separation and purification of the oil sludge, but also more seriously, if the oil is directly discharged , Because the toxic substances are seriously exceeding the standard, the direct and arbitrary discharge will cause serious environmental pollution.

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.

single screw pump

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!

waste drilling fluid treatment
waste drilling fluid 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.
