摘要(Abstract)：

针对牛驼镇凸起抬升时间和内幕结构研究不足的问题,运用地球物理方法和平衡剖面技术,研究牛驼镇凸起发育过程.结果表明:牛东断层与派生断层组成"Y"型,牛东断层下盘发育阶梯状逆冲断层.研究区构造演化经历3个阶段:J-K为凸起发育前潜山内幕形成期,其中J2末-J3为逆冲褶皱发育期;E1k-E3d为凸起形成期,其中E2s3-E3d为廊固—牛驼镇断块翘倾发育期;N-Q为凸起埋藏期.中生代主要受区域挤压和走滑运动的影响;新生代伸展构造、走滑运动及基底沉降控制牛驼镇凸起的演化,并与断层的产状相关.根据地震剖面、构造演化剖面特征得出内幕存在逆断层,E2s3凸起发育明显.通过分析构造演化对烃源岩、储集层、盖层、运移通道和圈闭的影响,预测牛驼镇凸起存在潜山内幕油气藏.

关键词(KeyWords)：牛驼镇凸起;平衡剖面技术;构造演化;构造成因;油气成藏
