Latest Patents

Hai Yang Zhao holds a patent for a plugging agent designed for use in extreme conditions. The patent, titled "Plugging agent with temperature-resistant, salt-resistant and high-expansion for plugging large fractures and preparation method thereof," outlines a unique formulation. The plugging agent system consists of several components, including a main agent (6%–10%), a cross-linking agent (0.6%–1%), an initiator (0.006%–0.01%), and additives (6%–14%), with the remainder being water. The preparation method involves creating a montmorillonite dispersion system, followed by the addition of the main agent and other components. The resulting gelation process occurs in an oven at temperatures ranging from 90°C to 20°C for 9 to 48 hours, achieving an adhesive strength of grade H and an expansion multiple of 50 to 80. This innovative agent demonstrates excellent strength and water plugging effects under conditions of 140°C and 250,000 degrees of mineralization.
