CO2 and H2S exist in the hydrocarbon zone and foramtion water,as the accompany gases of petroleum and nature gaso or components of formation water,which will cause corrostion to the cement sheath under certain conditions of humidity and pressure.It will decrease the cement sheath's alkalinity,which results in the decrease of cement sheath's strength,permeability increase,and places a premium on fluid channeling and borehole wall sloughs accident in plastic formation,shortening the oil- gas well's production lifetime and giving rise to tremendous ecomonic losses.
