摘　　要：为揭示注蒸汽热采开发对敏感性储层矿物的影响,利用X衍射、差热分析、电镜分析等手段对金家油田蒸汽驱替前后黏土矿物进行测试,确定了金家油田黏土矿物的附着状态,表征了该区块蒙脱石的脱水规律,结果发现敏感性稠油油藏热采开发中近井地带由于蒸汽温度场发育,储层渗流能力得到明显恢复,水敏伤害主要发生在蒸汽前沿低温度场区,因此开发中应贯彻"近热远防"的工艺策略。Laboratory study of clay minerals was conducted in order to find out the impact of steam stimulation. Analysis of means including X-ray diffraction, differential thermal analysis, and electron microscopy analysis were done. The major impact was from the water and heat. Injuries occurred mainly in the low temperature zone, and near wellbore flow capacity was restored. Development should implement the policy of＂ near-heat and far-prevent＂.
