What is water-based drilling fluid? Water-based drilling fluid is also called water-based drilling mud; its main component is: pottery soil barite. Water-based drilling fluid has the advantages of low cost, simple configuration, treatment and maintenance, wide sources of treatment agents, many types to choose from, easy control of performance, etc., and has a good effect of protecting oil and gas reservoirs. Therefore, it is used to drill oil and gas reservoirs at home and abroad. Most of the drilling sites are water-based drilling fluid, because of the low cost, but the disadvantage is that the water-based drilling fluid in the gypsum salt layer and mudstone layer is easy to cause water absorption and expansion, causing the well wall to collapse.
Water-based drilling fluid
Water-based drilling fluid treatment is more complicated than oil-based drilling fluid treatment. At present, the treatment methods for water-based drilling fluid that do not fall to the ground include: landfill method, mechanical dehydration method, incineration method, biological decomposition method, chemical solid-liquid separation method, etc. Each method has its own advantages and characteristics. Among them, the water-based drilling fluid is handled based on the principle of mechanical physics.
Solid waste after being processed by the system
At present, the water-based drilling fluid system used for the characteristics of water-based drilling fluid is a targeted and integrated solution. The water-based drilling fluid non-grounding system is mainly composed of: water-based drilling fluid conveying equipment, screening equipment, filter press equipment or centrifugal equipment and dosing devices. The configuration system equipment of different drilling projects is different. Its purpose is to treat water-based drilling fluid efficiently and environmentally through mechanical equipment.

After the water-based drilling fluid is transported into the special water-based drilling fluid non-grounding equipment, the large particles in the water-based drilling fluid are first processed by the screening device, and then the processed mud is again passed through the centrifugal equipment or filter press equipment to achieve mud water dewatering. The sludge and water are separated by the filter press, the sludge is collected and stacked, and the clean water is reused.
