High-temperature Resistant Modified Asphalt

  • In drilling fluid, it has the function of sealing micro fractures in the formation, preventing the collapse of exfoliative shale, providing good lubrication and anti collapse effects as well as resisting high temperature and reducing filtration. It can be directly applied to various water-based drilling fluid systems to reduce filtration and prevent wellbore collapse.
  • Comply with Q/SH1020 2315-2015 standard.
