摘要
针对双水平井蒸汽辅助重力泄油(SAGD)启动阶段循环预热期长、蒸汽消耗量大的问题,介绍了溶剂辅助启动、泡沫辅助启动、电磁加热启动和应力扩容启动4种双水平井SAGD快速启动技术的作用机理及其在应用方面的优缺点。认为应力扩容启动具有明显优势,建议在现有基础上继续开展相关研究,提高双水平井SAGD快速启动技术适应性;将不同快速启动技术联合使用是改善启动阶段效果的一条有效途径。
Focusing on the long circulating preheating time and large steam consumption of dual horizontal wells during the start-up phase by steam assisted gravity drainage （SAGD） process, this paper introduces the mechanisms of 4 fast start-up technologies of SAGD process for dual horizontal wells, which include solvent assisted start-up, foam assisted start-up, electromagnetic heating start-up and stress expanding start-up, and also analyzes each advantages and existing problems in their applications. It is suggested that the stress expanding start-up technology has obvious advantages and further related researches should be made to improve its technical adaptability, and the combination of these fast start-up technologies will be an effective way for improving the effects of start-up phase.
