一、Performance and characteristics
ACS-8, an anti-mud coating agent for drilling fluid, is an efficient and multi-functional anti-mud coating agent resistant to high temperature 200℃ and saturated salt. When added to the drilling fluid system, the wall protection ability can be increased on the basis of anti-mud coating, which can significantly reduce the friction and surface tension, improve the lubrication and anti-stuck ability of drilling fluid and prevent the mud coating ability of drill bit. The cuttings do not adhere to the well wall, prevent the formation of false holes, and improve the safety and stability of the underground。
