【图文】提高原油采收率原理(EOR)第九章-B

1、 VAPEX (Vapour Extraction Process The VAPEX (Vapour Extraction Process is technically similar to SAGD but instead of steam solvent is being injected into the oil sands resulting in significant viscosity reduction. The advantages envisioned by this innovation are: lower injection pressure and tempera

2、ture greater energy efficiency no emulsion to deal with no clay swelling phenomenon that damage the formation partial upgrading within the reservoir THAI(Toe-to Heel Air Injection Toe-to-Heel Air Injection, or THAI, is a proposed method of recovery that combines a vertical air injection well with a

3、horizontal production well. The process ignites oil in the reservoir itself, creating a vertical wall or front of burning crude (fire front that partially upgrades the hydrocarbons in front of it and drains the crude to a producing horizontal well. By creating heat in situ, the process negates the n

4、eed for injecting steam from the surface. The process also offers some potential for upgrading the bitumen in the reservoir as the process proceeds. 本章小结 1、基本概念：热力采油；稠油；特稠油；超稠油； 基本概念：热力采油；稠油；特稠油；超稠油； 蒸汽吞吐；蒸汽驱；火烧油层法； 蒸汽吞吐；蒸汽驱；火烧油层法；干式正向燃烧 干式反向燃烧法；湿式正向燃烧法； 法；干式反向燃烧法；湿式正向燃烧法；焦碳的 热值； 热值； 2、综合思考题（1）简述热力采油及其主要分类 综合思考题（ 方法。（ 。（2 地下燃烧法有哪三种方法？ 方法。（2）地下燃烧法有哪三种方法？比较其优 缺点。（ 。（3 缺点。（3）简述注热法和地下燃烧法提高采收率 的原理。（ 。（4 适合蒸汽驱、 的原理。（4）适合
