摘　　要：通过对储层岩样的XRD、SEM和敏感性评价等对秦皇岛33-1南油田储层损害因素进行了试验分析。分析结果表明,秦皇岛33-1南油田明下段埋藏浅,属高孔、高渗型储层。储层粘土矿物以伊/蒙混层为主。秦皇岛33-1南油田储层对流体流速、酸碱度、盐度和应力等变化比较敏感。钻完井过程中储层损害因素主要为固相侵入、水敏损害和应力敏感性损害。因此,实际钻采生产中,应适当的控制流体产出和注入速度、入井流体的酸碱度、盐度和固相侵入,以保护储层。Factors of reservoir damage for QHD33-1S oilfield are analyzed by XRD,SEM and reservoir sensitivity evaluation.Tests show that clay mineral of reservoir is illite smectite mixed layer,moreover,reservoir is sensitive to fluid velosity,salinity,pH value and stress change.Solid phase invasion,water sensitivity and stress sensitivity are main factors of formation damage during drilling and completion operations.
