| Abstract: | The experiments were conducted to study the ultra fine cement properties, including the particle size distribution, the initial and final setting time at 45 o C, compression strength, rheology and stability. The results show that the ultra fine cement has the tiny particle size, high stability, low plastic viscosity and dynamic shear force, so it can be used in the water plugging and working in abandoned layer; by the request of the field application the compatible retarder should be added and control the initial setting time in the scope of 4-10 h; the best formula of ultra fine cement for water plugging is 1 3:1 0 slurry with 2% additive. Finally, the field application was introduced. |
