This paper addresses optimization of well pattern, array and spacing for surfactant/polymer flooding in Jin 16 block of Liaohe oilfield in respects of interbed oil -controlling factors, control degree of chemical flooding, central well group completeness, injectivity and productivity, injection rate, improved recovery efficiency, economic benefits and so on based on successful domestic experiences, fine geological modeling, reservoir simulation and physical simulation experiment with full consideration of the complexity of reservoir geology. The technical and economical results are compared and analyzed. This research provides necessary pro-phase preparation for converting development scenario and achieving sustainable oilfield production.%在总结国内成功经验的基础上,通过精细地质建模、数值模拟结合室内物理模拟实验,充分考虑油藏地质特点,从夹层控油因素、化学驱控制程度、中心井组完善程度、注入采出能力、注入速度、采收率提高值、经济效益等方面,对辽河油田锦16块二元复合驱井网模式、井排方位以及合理井距进行优化研究,对比分析技术经济效果,为开发方式的转换作必要的前期技术储备,以实现油田产量的有效接替.
