在重油开采作业面临着油价和经济利润萎靡不振的局面下,从技术角度来看蒸汽辅助重力泄油(SAGD)和蒸汽提取(Vapex)法似乎很有远景。本文在对比重油热采方法SAGD与Vapex的基础上详细介绍了这两种方法的油藏筛选指南。
Steam oil-assisted gravity drainage (SAGD) and steam extraction (Vapex) approaches seem to have a long-term perspective from a technical point of view, as oil-heavy mining operations are facing sluggish oil prices and economic profits. Based on the comparison of heavy oil thermal recovery methods SAGD and Vapex, this paper introduces the reservoir screening guidelines of these two methods in detail.
