Introduction of solid-liquid separation technology
The ultimate intention of liquid separation, theoretically speaking, should be to completely separate the two phases of solid and liquid to obtain their respective pure components: solid and liquid. According to the current development, solid-liquid separation is fundamentally two methods, namely sedimentation separation and filtration. The sedimentation separation can be divided into two kinds, namely gravity sedimentation and centrifugal sedimentation.
Drilling fluid solid control system supporting status and improvement measures
Drilling fluid solid control system is a solid control method for drilling fluid in the exploitation of oil and gas resources to separate and control it in order to improve drilling efficiency and realize the recycling of drilling fluid. Therefore, it is also known as drilling fluid purification system.
Oil, are we out of it?
At the dawn of the 20th century, the most foul-smelling environmental challenge facing the world's cities was not slums, sewage or coal ash, but horse manure. In London in 1900, about 300,000 horses pulled taxis and stagecoaches, as well as wagons, flatbeds and haywagons, leaving a trail of horse manure in their wake. New York City has 100,000 horses, and its citizens endure the same problem - they have to wade through flowing sewage on rainy days and through fly-flying dung piles on sunny days.

Drilling waste and environmental impacts
The pollution caused by drilling waste to the environment is mainly due to the fact that drilling waste contains a large number of water-soluble heavy metal ions and inorganic substances, which will gradually spread and transfer with the passage of time after dissolving in the surface and groundwater, and eventually bring great threats and impacts on the living environment of animals and plants, and even lead to the death of animals and plants.

Solid control system overview and workflow
During the drilling process, mud enters the formation through the drill pipe, and the drilling fluid is discharged together with the drilling waste after being used. Because mud is expensive and can damage the environment, the solid control system comes into being in this situation.
Introduction to basic knowledge of fracturing flowback fluid treatment
Most of China's oil and gas fields have reached the middle and late stage of exploitation, and hydraulic fracturing can improve the exploitation efficiency of oil and gas fields. However, a large amount of frac flowback fluid is produced during production. The mixed waste liquid is composed of fracturing fluid and pollutants in the formation, and has three characteristics of high COD, high suspended matter and high salinity.
