According to the fact of offshore surface casing cementing operations, a dynamic response has been designed for on site operation conditions and the design parameters that should be adopted for permissible safe stress and safe allowance have been obtained.

The authors have discussed the fundamental process of surface CASING modification. The authors have also solved the Clark equation and gotten surface process rate constants, bulk process rate constants and surface activation depth.

解Clark方程得出表面过程速率常数、体相过程速率常数以及CASING表面反应深度。
