目前我国大部分油田的开发已处于“三高”阶段,采用调层、加密井网、强化注水等提高水驱动用状况和水驱效果不明显,而注气驱、注气吞吐开发比其它三次采油技术投资少、效益高,具有巨大应用空间。本文通过分析注气提高采收率在国内外发展的技术现状,为进一步针对不同的油田情况,研究注气提高采收率提供研究资料。
At present, the development of most of the oilfields in China has been at the stage of “three highs”. It is not obvious to adjust the water driving conditions and water flooding effects by adjusting the layers, enhancing the well pattern, strengthening the water injection, etc. However, the gas injection flooding and gas injection throughput development ratio Other tertiary recovery technology less investment, high efficiency, with great application space. In this paper, by analyzing the technical status quo of gas recovery enhanced oil recovery at home and abroad, providing research data for further research on gas recovery enhanced oil recovery for different oil fields.
