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.
CO2和H2S作为石油和天然气的伴生气或地层水的组分存在于油气层或地层水中,在一定的湿度及压力条件下会对固井水泥环产生腐蚀作用,从而降低水泥环的碱性,使水泥环强度下降,渗透率增大,并诱发流体窜流、塑性地层井壁跨塌等事故,从而缩短油气井的生产寿命,造成巨大的经济损失。
