Water-based drilling fluid is also water-based drilling fluid, and its main component is: barite water porphyry. Water-based mud has the advantages of low cost, easy configuration, processing and maintenance, wide selection of treatment agents, many types to choose from, and easy performance control.
Due to the low cost, most drilling sites use
water-based drilling fluids, but the disadvantage is that water-based drilling fluids can easily cause water expansion in gypsum-salt layers and mudstone layers, resulting in wellbore collapse.
At the drilling site, the treatment of water-based drilling fluid is more difficult than that of oil-based drilling fluid. At present, the treatment methods of water-based drilling fluid are as follows:
landfill method. Mechanical dehydration incineration method. Biological decomposition method, solid-liquid chemical separation method, etc.
Each method has its own advantages and characteristics.
At present, the water-based mud treatment system is a targeted comprehensive solution according to the characteristics of water-based drilling mud.
Water-based mud treatment technology is mainly composed of water-based mud supply equipment, screening equipment, filter press equipment or centrifugal equipment and metering devices.
There are some differences in the equipment that configures the system for different drilling sites.
