摘　　要：从深层稠油油藏特殊性出发,剖析转换开发方式存在的主要技术难点。通过对洼60-H25井组立体井网蒸汽驱机理的分析,提出深层稠油油藏转蒸汽驱开发应合理采用不同井型、立体井网架构、多种驱动力并存并以创造驱油环境为核心的方案设计思路。该研究对深层稠油油藏蒸汽驱开发具有重要指导意义。Based on the particularities of deep heavy oil reservoirs,the key technical difficulties existing during the conversion of production methods are analyzed in the paper.The mechanism of steam flooding in a tridimensional well pattern called well group Wa60-H25 is analyzed and a program design concept is proposed for converting to steam flooding for deep heavy oil reservoirs,which mainly involves adopting different well types,tridimensional well patterns,multiple driving forces and creating oil displacement environments.This study is of great guiding significance in the development of deep heavy oil reservoirs by steam flooding.
