Drilling waste mud treatment is currently a major problem in oil fields

Waste drilling mud is one of the main pollution sources in the oil and gas industry, and its waste disposal is currently a major problem that plagues oil fields.

The oilfield drilling waste mud treatment process is the immediate disposal of waste drilling mud (drill cuttings) while drilling, meeting the requirement of “mud zero discharge”, reducing land use and reducing environmental pollution. This technology is to change the “end treatment” to “full process control”, the waste mud is diluted-flocculated-separated into three parts: cuttings, mud cake and water, and the solids in the mud are treated by water washing, flocculation separation and chemical reaction. Make the cuttings and mud cake meet the discharge standard. After the harmful components and chloride ions in the mud are separated into the water, they are dehydrated by vacuum adsorption or extrusion to make mud cakes. At the same time, the waste water separated by centrifugation is subjected to air flotation. The sedimentation, filtration system, and reverse osmosis system are used for concentration treatment. After treatment, the up-to-standard wastewater can be reused for drilling recycling.

The main equipment for the treatment process of waste oil drilling mud includes: drying shale shaker, drill cuttings dryer, drilling fluid centrifuge, screw conveyor, screw pump, etc. KOSUN’s mud zero discharge 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 zero discharge of the mud.

There are many kinds of waste mud treatment processes in oilfield drilling. Each treatment solution 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.

Why is it difficult to dehydrate and separate water-based mud from oilfield drilling?

The main factor that is difficult to dehydrate and separate water-based mud for oilfield drilling is the complex nature and many components of hydraulic mud.

The product composition of water-based mud in the drilling process is more complicated. The main components of oilfield drilling mud are multiphase colloids such as water, clay, drill cuttings, flocculants, and drilling fluid additives. Chemical agents such as bentonite, weighting agents, inorganic salts, baseless polymers, organics, synthetic polymers and surfactants are often added in the configuration to improve the performance of water-based muds. Groundwater, drill cuttings, clay, etc. that are collected when drilling into the formation in the oil field. Its pH value is a little alkaline, generally 8.15-9.10, the moisture content is usually between 35% and 90%, and the solid phase particle size is generally between 0.01μm2 and 0.1μm2.

The properties of oilfield drilling mud are related to underground structures and rock properties. As the drilling depth increases, the downhole structure becomes more complicated, and the corresponding mud performance requirements and chemical configuration become more complicated. The corresponding pollutants in the solid waste discharged outside are also increasing, the content and the concentration are also increasing. Therefore, it is difficult to dehydrate and separate the water-based mud in oilfield drilling, and it will affect the quality and progress of the drilling project in severe cases.

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.
