我国当前和未来都将面对特高含水期油藏、低渗透、稠油等难开发油藏以及海上、沙漠油田的一系列改造开采问题,随着油田开采难度的增大,技术要求越来越高,必须运用现代科学技术改造传统的开采工艺。本文对微生物采油、热力采油、空气催化氧化法采油等新技术进行详细的分析和探讨,这些工艺的应用有利于延长油田稳产年限,降低开采难度,从而提高采油速度及提高最终采收率。
At present and in the future, China will face a series of problems in the development of ultra-high water-cut reservoirs, low permeability and heavy oil reservoirs, as well as offshore and desert oilfields. As the difficulty of oilfield exploitation increases, the technical requirements will gradually increase The higher must be the use of modern science and technology to transform the traditional mining process. In this paper, new technologies such as microbial oil recovery, thermal oil recovery and air catalytic oxidation are analyzed and discussed in detail. The application of these technologies is beneficial to prolong the stable production of oilfields, reduce the difficulty of mining and improve the recovery rate and ultimate recovery.
