摘　　要：在研究大量文献的基础上,总结了注蒸汽采油的机理,概述了稠油注蒸汽热采的研究现状与发展趋势,着重探讨了稀油注蒸汽热采的应用前景、研究现状以及稀油注蒸汽热采还需要深入研究的课题。研究认为:稠油注蒸汽热采已是比较成熟的技术,在稠油开发中占有重要的地位,其发展趋势为利用天然气、溶剂、高温泡沫、聚合物等来改善注蒸汽热采效果;稀油油藏水驱、聚驱后转注蒸汽热采具有可行性,今后需重点解决的问题包括采用煤或核能生产蒸汽、采用水汽交注、蒸汽泡沫等方法提高稀油油藏注蒸汽热采的采收率。Based on literature investigation,the mechanisms of oil recovery by steam injection were summarized;the research status and development trend of thermal recovery of heavy oil by steam injection were discussed;and the application prospect,research status and subjects needed to be further studied in thermal recovery of light oil by steam injection were investigated emphatically.It can be concluded that thermal recovery of heavy oil by steam injection is a relative mature technology,which occupies an important position in the production of heavy oil.Addition of dissolvent,high-temperature foam and polymers into the injected steam can improve the effect of thermal recovery of heavy oil by steam injection,which is the development trend for thermal recovery of heavy oil.It is feasible to change into use thermal method of steam injection to recover reservoirs of light oil after water or polymer flooding.and the issues needed to be emphatically studied include steam generation by using coal or nuclear energy,adopting alternative injection of water and steam,high-temperature foam to increase the recovery efficiency of light oil reservoir.
