摘要：
Based on the mathematical model of high pressure injection cement liquid, a formula of pressure distribution is derived in the district with the cement liquid injection and the raw water area, and the pressure in well bottom to fade away as stop injection cement liquid. The pressure in well bottom relation with the time of the injection and the viscosity of cement liquid, and the permeability in the confined aquifer are analyzed. The empirical formula of the injection pressure with the water-cement ratio is established. The formula can consequently guide the engineering; the good fulfillment results are obtained.
