摘要：
Determine the best formula of the double excitation inorganic adjustable plugging agent: 15% slag + 0.8% activator + 4% dispersant + 2.5% retarder, with a curing time of 32h, and a curing strength over 1.4Mpa. The initial viscosity of adjustable plugging agent is 36mPa.s, and after curing for eighteen hours in 85 degrees Celsius, viscosity is less than 320mPa.s. For cores with different permeability, the water plugging rate of adjustable plugging agent is more than 90%.
