Drilling mud filters out sewage treatment pond

Technical Field

The utility model relates to an oil drilling sewage treatment technical field, concretely relates to drilling mud filters out sewage treatment pond.

Background

Petroleum is one of the most critical fuels and chemical raw materials in the world, and the exploitation of petroleum is mainly realized by means of drilling technology. In the process of petroleum drilling, drilling fluid is required to be used, and the drilling fluid is a general term for various circulating fluids meeting the requirements of drilling work in multiple functions in the drilling process. The drilling fluid is the blood of the well, also called drilling flushing fluid. The drilling fluid can be divided into clear water, slurry, clay-phase-free flushing fluid, emulsion, foam, compressed air and the like according to the composition. The clean water is the earliest drilling fluid, does not need to be treated, is convenient to use and is suitable for regions with complete rock stratums and sufficient water sources. The mud is widely used drilling fluid and is mainly suitable for unstable rock formations of hole walls, such as loose rock formations, fracture development, easy collapse and block falling, water swelling and peeling, and the like.

The drilling mud is mixed with oil and sewage after being used, and needs to be replaced after being polluted to a certain degree, and if the waste drilling mud is directly discharged to the natural environment, the oil and other pollutants contained in the waste drilling mud can seriously pollute the natural environment, so the waste drilling mud needs to be treated and then discharged. At present, drilling mud is generally filtered, the filtered sewage is subjected to harmless treatment and then discharged, and the left mud can be recycled after being processed, so that the cost is saved and the pollution to the environment is reduced.

At present, the sewage filtered from the drilling waste gas and mud is generally removed by adding chemical reagents to remove inorganic pollutants, then the floating impurities are removed by centrifugation and other steps after the reaction, finally the organic impurities are removed by microorganisms and other modes, and the sewage is discharged into a natural water body after reaching the standard. The step of adding chemicals is generally carried out in a reaction tank, but the filtered sewage usually contains certain granular impurities such as sludge and the like, and the sediment is easy to occur in the reaction process, so that the water body purification degree at the bottom is not enough, and a better sewage treatment tank is needed.
