The invention provides an advanced completion fluid specifically designed for ultra-high pressure and high temperature (ultra-HPHT) oil and gas wells. This new fluid, comprising an organic salt, an inorganic salt, and two additives (a chelating agent and a stabilizer), offers high density, low corrosion, thermal stability, low turbidity, and long-term storage stability. It addresses the limitations of traditional completion fluids, enhancing wellbore stability, reducing equipment degradation, and improving the efficiency and safety of extraction processes under extreme conditions.
