Composition of KOSUN Large Shale Gas Drilling Mud Station
Due to the characteristics of shale, oil-based mud has become the key to shale gas drilling. The shale gas drilling solids control system is a system equipment specially used to deploy oil-based mud for shale gas drilling. The mineral composition of shale is relatively complex. In addition to common clay minerals such as kaolinite, montmorillonite, and illite, it is also mixed with minerals such as quartz, feldspar, mica-calcite, dolomite, pyrite, and apatite. Clay minerals are easily swelled in contact with water, which affects normal drilling and causes downhole complexities such as wellbore collapse. At the same time, it causes drilling fluid pollution and reduces production capacity in the later stage of production. This is the main reason for the use of oil-based mud. KOSUN large-scal
