摘　　要：浅薄稠油热采吞吐进入中高周期开发阶段，吞吐效果变差，热效率降低。为了提高高周期开发效果，充分利用热能，根据该阶段生产特点，研究应用了合理有效动态配汽技术、弱淹层、中淹层利用时机优选技术和中厚层挖潜技术。措施实施后，稠油中后期开采热能利用率提高，油层、井筒热损失降低，稠油实现了持续稳产，吞吐技术指标提高，热采综合递减下降。Huff and puff effect and thermal efficiency decrease as thermal recovery of thin and shallow heavy oil enters into medium or long cycle stages． In order to effectively utilize thermal energy several technologies are studied including rational effective and dynamic steam allocation technology optimization of opportunity to put weak and medium flooded reservoirs into production and production potential tapping in medium to thick heavy oil reservoirs． Field appoication of these technologies increase utilization efficiency of thermal energy realizes stable production of heavy oil and lowers the overall decline rate of thermal recovery．
