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。
為揭示註蒸汽熱採開髮對敏感性儲層礦物的影響,利用x衍射、差熱分析、電鏡分析等手段對金傢油田蒸汽驅替前後黏土礦物進行測試,確定瞭金傢油田黏土礦物的附著狀態,錶徵瞭該區塊矇脫石的脫水規律,結果髮現敏感性稠油油藏熱採開髮中近井地帶由于蒸汽溫度場髮育,儲層滲流能力得到明顯恢複,水敏傷害主要髮生在蒸汽前沿低溫度場區,因此開髮中應貫徹“近熱遠防”的工藝策略。

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".
