摘　　要：美国继页岩气、致密油成功开发之后，残油区的开发也取得了重要进展。据Melzer咨询公司评估，美国残油区开发有望将其原油可采储量提高30％～50％，成为下一个大幅度增储上产的战略接替区。介绍了残油区的定义、生成、储层特征及资源潜力，对美国残油区开发现状和潜力进行评估，并就其勘探开发技术和未来的研究方向进行了讨论一虽然残油区的勘探开发刚刚起步，但已显示出巨大的资源潜力和良好的开发前景，其主体技术二氧化碳气驱强化采油（CO2－EOR）兼有增油环保双重优势，这不仅给未来老油田增储上产开辟了一奈新路，还为CO2埋存提供了新的目标区，The United States has made significant progress in development of residual oil zone following the successes in development of shale gas and tight oil. Based on the assessment made by Melzer Consulting Firm, development of US residual oil zone is expected to increase recoverable oil reserve by 30-50 percent. It is the next strategic replacement zone for substantial increase of reserve and production. This paper makes briefings about definition and sourcing of residual oil zone as well as the characteristics and potential of reservoirs. It also evaluates the present conditions and development potential of US residual oil zone and discusses exploration and development technology and its future development orientation. Exploration and development of residual oil zone has shown a great potential of resources and a promising prospect for development though it is just in its preliminary stage. The main CO2- EOR technology is advantageous both in increase of oil production and protection of the environment. It not only opens up a new way for old oilfields to increase their oil production but also provides a new target area for CO2 burial and storage.
