摘　　要：针对曙一区薄互层稠油油藏蒸汽吞吐开发后期所面临的矛盾和问题,在重构地质模型、充分认识油藏特点和剩余油分布规律的基础上,就该类油藏水平井井位部署、井网井距选择、钻井轨迹及其他参数设计等进行研究和优化。实施后取得较好的开发效果,初步形成了薄互层稠油油藏水平井二次开发的总体思路和关键技术。The thin-interbedded heavy oil reservoir in Shu 1 area of Liaohe oilfield has many problems in the late stage of cyclic steam stimulation.This paper studies and optimizes the locations,well pattern and spacing,drilling trajectory and other parameters of horizontal wells on the basis of geological model reconstruction and fully understanding of reservoir characteristics and remaining oil distribution.Good development response has been achieved thus provided a general idea of redevelopment by horizontal wells for thin-interbedded heavy oil reservoir.
