Water-based Mud zero discharge and oil-based Mud zero discharge

Oil-based Mud zero discharge mainly for directional wells and ultra-deep wells. Directional wells and ultra-deep wells require an oil-based mud system to prepare the mud. The oil-based mud contains expensive diesel or white oil, and the oil-based drilling solids control system treats the oil-based mud. If the drilling cuttings still contain oily mud, if the mud is not treated on the ground, the mud will be wasted and the drilling cost will increase.

Water-based Mud zero discharge mainly for shallow wells. Water-based mud is mainly prepared by adding chemicals or industrial salt to the soil. The solids control system uses water-based mud drilling system. The drilling waste generated by the water-based mud drilling system also contains effective mud. Disposal will also cause waste of mud, which needs to be recycled without mud disposal.

Mud zero discharge is the key to drilling waste treatment. It is the result of improved drilling technology, replacing traditional mud pools, reducing drilling environmental pollution and improving the necessary methods for environmental protection. The current Mud zero discharge includes water-based Mud zero discharge and oil-based Mud zero discharge. The two methods of Mud zero discharge are determined according to the mud treatment system adopted in the drilling.

Mud (drilling fluid), which is used to lubricate the drill bit, cement the well wall and cool down during the drilling process. In the whole drilling process, mud is of great significance to reduce drilling accidents and improve drilling efficiency. Generally, water-based mud systems and oil-based mud systems are mainly used in drilling sites.

However, the Mud zero discharge through the secondary filtration separation and recovery of drilling waste, which directly saves a lot of drilling mud, especially oil-based mud. Therefore, Mud zero discharge is the key to drilling solids control and drilling waste disposal.

Construction Waste treatment and reuse

Under the new pattern of circular economy, how to dispose of construction waste(Construction Waste treatment) with an annual increase of billions of tons has become one of the problems that the industry urgently needs to solve. In recent years, with the acceleration of urban construction and renovation, the problems of construction waste pollution and garbage siege have become increasingly prominent. In terms of inventory, the current increase in domestic construction waste reaches about 3.5 billion tons per year.

According to the source of construction waste, it is mainly divided into land excavation waste, road excavation waste, old building demolition waste, construction waste and building material waste. The demolition phase of buildings and the construction phase of new buildings are the key points for the control of construction waste. The demolition of old buildings and new construction accounted for 58% and 36%.

At present, our country’s treatment of construction waste is still in the relatively extensive landfill and stacking stage. In fact, construction waste is a renewable resource. After scientific recycling, separation, screening, and smelting, it can completely turn waste into treasure to restore its original performance, and reuse it as a renewable raw material. However, transforming construction waste into qualified, high-quality aggregates that can replace natural sand and gravel, and then into market-recognized products, is the biggest challenge facing companies.

Oilfield Drilling Waste Mud Treatment Process and Equipment

Waste drilling mud is one of the main pollution sources in the petroleum and natural gas industry. The Oilfield Drilling Waste Mud Treatment Process is to treat the waste drilling mud (drill cuttings) immediately while drilling to meet the requirements of “mud zero discharge” and reduce environmental pollution. This technology is to dilute, flocculate and separate the waste mud into rock debris, mud cake and water, and process the solids in the mud through water washing, flocculation separation and chemical reaction to make the rock debris and mud cake meet the discharge standard.

The Oilfield Drilling Waste Mud Treatment main equipment includes: shale shaker, drill cuttings dryer, drilling fluid centrifuge, screw conveyor, screw pump, etc. KOSUN’s zero discharge mud system can effectively control the water content of drilling cuttings (6%-10%) in the drilling mud, stabilize the liquid phase performance, and achieve the purpose of mud zero discharge.

There are many kinds of waste mud treatment processes 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.

KOSUN Mud Zero Discharge System Processing Flow

The Mud Zero Discharge System developed by KOSUN mainly includes shale shaker, centrifuges, cuttings dryers, and screw conveyors. After processing, it can reach an oil content about 2-5%, which is in line with national and industry standards.

After dewatering centrifuge separation and multifunctional purification unit, the harmful part of the mud is discharged with the solid phase. The liquid phase can be used to prepare the mud, discharge as wastewater or irrigate, and the solid part is solidified and then landfilled.

On-site centralized processing while drilling, using physical centrifugal separation technology to recover most of the base oil on-site, reducing the oil content and total amount of waste (the solid phase oil content of the spin dryer is 2%-12%, and the solid phase oil content of the centrifuge is about 13%, the treated solid phase is transported to the centralized treatment station for further treatment, and the liquid phase is returned to the circulation system for use. The advantage of on-site centrifugal deoiling while drilling is that it reduces the total amount of waste at the source, recovers reusable oil-based mud, and the treated waste is easy to store and transport, which greatly reduces the time and energy consumption of subsequent processing.

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.
