摘　　要：本文应用全直径岩心水驱油实验装置研究了喇、萨、杏油田表外储层油水运动特征和水驱油效率，说明了表外层泥质含量高，注水时临界速度低，微粒运移较严重，对油田生产不利。By applying experimental apparatus of water displacing oil in whole diameter core, this paper studies oil-water movement characteristics and water displacing oil efficiency in untabulated reservoirs in La, Sa, Xing oil fields, demonstrating that shale content in untabulated reservoirs is high, critical speed during waterflooding is low, particle migration is active which affect oil field production.

关 键 词：表外储层 水驱油效率 相对渗透率 临界速度
