Abstract

Abstract: The carbonation mechanism of CO2 corrosion on oilwell cement shearth at temperatres lower than 110℃is analyzed from a cement chemistry point of
view, and thecriteria of corrosion are discussed on the basis of thermodynamic principles. Ways to pre-vent oilwell cement shearth from CO2 corrosion for
domestic oilfields with high CO2 concentrations are proposed. A (cited ) criterion for predicting carbon-ation of the shearth is also recommended.

Key words: Oilwell cement, Well cementing, CO2corrosion, Thermodynamics, Mechanism
