Polymer Drilling Fluid with Micron-Grade Cenosphere for Deep Coal Seam
Traditional shallow coal seam uses clean water, solid-free system, and foam system as drilling fluid, while they are not suitable for deep coal seam drilling due to mismatching density, insufficient bearing capacity, and poor reservoir protection effect. According to the existing problems of drillin...
