摘　　要：为了解决埋深超过 2 0 0 0m的深层稠油开采难的问题 ,提出了一种超临界压力蒸汽发生器的开采方案 ,并与其他注汽方案进行了比较 ,同时研究了超临界压力热流体在地面管线和井筒中流动的规律。结果表明 ,利用超临界压力热流体注入井底后不仅能提高注入压力 ,而且减少了热损失。采用超临界压力蒸汽发生器能解决常规注汽难的问题 ,有利于开发深层稠油。超临界压力水注入井底时 ,井底注入压力比常规注汽井底压力增大 1 5MPa以上 ,且流量越小 。In order to explore the underground heavy crude over 2000 meters in depth,a project of steam injection for supercritical pressure steam generator was designed and compared with the project of hot water injection by raising pressure of the former set hot water boiler. The flowing rules of hot fluid with supercritical pressure in the pipeline and well bore were discussed. The supercritical pressure hot fluid injection project can improve the injection pressure and save the heat energy. The injection pressure at bottom hole for supercritical pressure steam injection project increased 15 MPa more than that of conventional hot water flooding.
