蒸汽辅助重力泄油技术研究进展

Progress of steam assisted gravity drainage

对国内外SAGD技术研究进展情况进行了分析。从布井方式和井筒水动力、人工举升方法、经济评价指标3个方面详细讨论了目前SAGD技术的最新研究,探讨了国外先进的技术方法。指出今后的研究方向是针对国内油藏埋藏深、特稠油、地质构造复杂现状的研究,适应国际油价波动的经济评价方法对SAGD项目设计十分重要。

This paper addresses the progress and development of SAGD technology at home and abroad in aspects of well pattern and wellbore hydrodynamics,artificial lifting method,and economic assessment index,and points out the direction of future research in China shall focus on deep reservoir,super heavy oil and complex geology.A suitable economic assessment method to international oil price fluctuation is very important to a SAGD program.
