KOSUN Comprehensive Drilling Waste Treatment Solution

Solid-liquid separation is an important part of the drilling waste treatment process. The smaller the proportion of the water content in the waste, the smaller the volume of the remaining solids, and the smaller the required treatment cost, which can effectively control the treatment cost and reflect economic benefits. In recent years, domestically developed orifice plate filter presses, filter belt dewatering conveyors, horizontal screw centrifuges and other dewatering devices have promoted the improvement of drilling waste treatment technology.

This kind of treatment route is to let the sewage pond that collects wastes settle naturally first , and perform conventional sewage treatment on the free water produced after natural settlement; at the same time, add flocculants and coagulants to the sludge part for chemical destabilization treatment, and then pass it through dewatering devices such as centrifuges, filter belt dehydrators, orifice plate filter presses further separate solids and liquids, and finally solidify and treat the separated solids and moisture respectively, thereby completing the elimination of drilling and completion waste fluids. Harmful treatment. In this scheme, since the dehydration device is still in the trial stage, the degree of automation is not high and the efficiency is low.

Oilfield Drilling Waste Mud Treatment Process

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 process 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 process

Oilfield drilling waste mud treatment process 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.

The main equipment of oilfield drilling waste mud treatment process includes: drying shaker, drill cuttings dryer, drilling fluid centrifuge, screw conveyor, screw pump, etc. The KOSUN mud non-grounding system can effectively control the drilling cuttings in the drilling mud Water content (6%-10%), stable liquid phase performance, to achieve the purpose of mud drying treatment without falling to the ground.

There are many kinds of oilfield drilling waste mud treatment process 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.

Dewatering principle of decanter centrifuge

The decanter centrifuge uses the principle of centrifugal sedimentation to separate the drilling suspension. The suspension enters the drum from the feed pipe through the liquid outlet hole in the screw pusher, and the solid particles are pushed to the inner wall of the drum under the action of centrifugal force and pass through the screw. The blades on the pusher are pushed to the slag discharge port at the small end of the rotating drum, and the liquid phase overflows through the overflow hole at the big end of the rotating drum. Such continuous circulation, in order to achieve the purpose of continuous separation. Sedimentation centrifuges belong to the category of horizontal spiral centrifuges, and the full name is horizontal spiral sedimentation centrifuges. crown

Dewatering principle of the decanter centrifuge: The decanter centrifuge uses the density difference between the solid and liquid phases, and under the action of centrifugal force, accelerates the sedimentation speed of the solid phase particles to achieve solid-liquid separation. The specific separation process is that the sludge and the flocculant liquid are sent into the mixing chamber in the drum through the inlet pipe, where the mixing and flocculation are carried out (if the sludge pump is dosing before the pump or the pipe is behind the pump, the flocculation reaction has been advanced) Due to the high-speed rotation and frictional resistance of the rotor (screw and drum), the sludge is accelerated inside the rotor and forms a cylindrical liquid ring layer (liquid ring area). Under the action of centrifugal force, the solid particles with larger specific gravity settle to the A mud layer (solid ring layer) is formed on the inner wall of the drum, and then the relative speed difference between the spiral and the drum is used to push the solid phase to the cone end of the drum. After pushing out the liquid surface (shore area or drying area), the mud can be dehydrated and dried. It is discharged to the slag discharge port, and the supernatant is discharged from the big end of the drum to achieve solid-liquid separation.

How to deal with drilling waste at the well site with natural radiation?

KOSUN is a professional manufacturer in drilling waste management. KOSUN has many years of drilling waste management experience. It can provide supporting and efficient oilfield drilling waste mud treatment equipment for different types of waste drilling fluids, especially for waste oil-based mud and waste water-based mud. With rich experience in treatment, we can also provide professional drilling solid waste treatment equipment.

There are two main aspects of the impact of radioactive materials on people: one is that the radioactive material emits rays, it will not directly contact the body, as long as the distance is sufficient, it will generally not cause harm to the body. On the other hand, radioactive pollutants are in direct contact with the body, which is a great harm. We must be very careful to avoid contact with these pollutants as much as possible, so as not to cause unnecessary harm, but also as much as possible to avoid pollution and harm to the environment.

Natural radioactive materials can be treated by appropriate methods, by injecting waste into blocked or abandoned wells, and ensure that the water level is below the groundwater level; or discharge into the ocean after meeting the requirements of relevant environmental protection laws and regulations; or transform it within the allowable content of the environment, and stored in a specially designated place for storing natural radioactive waste; it can even be discharged into an isolated and non-evaporable pool. In order to better solve the problem of radioactive waste disposal and reduce disposal costs. Where radioactive sources are found, the equipment and tools used will also be contaminated by radioactive waste. Therefore, they must be properly handled to prevent secondary pollution.

Drilling mud solid control and waste management

Introduction of Drilling mud solid control system:

Solid control system is a technique used in a drilling rig to separate the solids in the drilling fluids that are crushed by the drill bits and carried out of the well surface. Normally, a solid control system contains five stages: the mud tank, shale shaker, vacuum degasser, desander, desilter, and centrifuge. The shale shaker is used to separate big solids with diameter above 75μm, the desander addresses solids from 45-74μm, and the desilter segregates solids between 15-44μm. Sometimes the desander and desilter are combined as one high efficiency mud cleaner. When air enters the drilling fluids, a vacuum degasser is used to separate the air. When there is no air in the mud, the degasser works as a big agitator. All these stages are mounted on the top of the mud tank. After separating the solids, the clean mud can be pumped into the borehole again.The mud system with 4 phases of solids control process can be understood as the 5 phase purification system. From shale shaker, vacuum degasser, to Desander cone, Desilter cone, and the decanting centrifuge: different working principle, different separation point. Every well drilling requires such a system to process drilling mud. However, per different well depth and different drilling conditions we’ll get different configurations and different results.

Introduction of Drillingmud waste management:

Drilling waste management system, also called as drill cutting treatment system or drilling cutting management system. According to different applications, it can be classified as water-base drilling waste management system and oil-base drilling waste management system.

The main Drilling waste management equipments are drying shaker, cutting dryer, decanter centrifuge, screw conveyor, screw pump and tanks. The drilling waste management system can effectively control the moisture content (6%-15%) and oil content (2%-8%) in drilling cuttings and stabilizes the liquid phase performance.
