Liaohe oilfield has abundant heavy oil resources and complex geological conditions. During almost 30 years of development , a complete set of technologies has been developed and 8 key technologies have been improved for developing heavy oil from mid - deep reservoirs, thereby achieved stable high production of heavy oil and remarkable development response in Liaohe oilfield. This paper summarizes the technological achievements and understandings in heavy oil development in Liaohe oilfield, and provides technological references to the development of similar heavy oil reservoirs.%辽河油田稠油资源丰富,油藏地质条件极为复杂,在近30 a的开发实践中,形成了一整套适合中-深层稠油油藏特点的开发技术,完善配套了8项稠油核心开发技术,支撑了辽河油田稠油持续高产稳产,取得了显著的开发效果.结合辽河油田稠油开发实际,分析总结了稠油开发形成的技术成果及认识,可为同类稠油油藏的开发提供技术借鉴.
