摘　　要：喇萨杏油田进入高含水后期开采阶段后 ,针对多层非均质油层的特点和开发矛盾 ,立足于地质研究和矿场试验 ,形成与发展了多次加密调整、稳油控水、控水挖潜和聚合物驱油等重大技术。在对这些技术及应用效果进行总结与概括的同时 ,提出了喇萨杏油田今后进一步提高采收率的攻关方向。Since La-Sa-Xing ( refers to Lamadian,Saertu and Xingshugang reservoirs in Daqing oilfield ) reservoirs entering into high water cut stage,aimed at purposes of recognizing the reservoir’s property and development contradictions of multi zone heterogeneous pay zones,based on geological study and field test,multi time infilling adjustment,stabilizing oil production and controlling water cut techniques,tapping oil potential through controlling water cut and polymer flooding are formed and developed. As summing up these techniques and application achievements,further study direction in enhanced oil recovery is put forward in La-Sa-Xing reservoirs.
