中原油田地处东濮凹陷，油层条件苛刻，属于高温、高盐复杂断块油藏，经过三十多年的勘探开发，已整体 处于中、高含水开发阶段。通过梳理中原油田近十年在气驱、化学驱等三次采油技术的发展，介绍了各项技术在 不同油藏的研究成果及应用实践，指出了中原油田开展三次采油取得的认识及发展方向，为国内外高温高盐油 藏开展三次采油技术提供借鉴。表1参20

Zhongyuan oilfield，located in Dongpu Depression，is a complex fault-block reservoir with high temperature and high salt. After more than 30 years of exploration and development，it is in the stage of development with medium and high water cut. The development of tertiary oil recovery technologies in Zhongyuan oilfield in recent ten years was summarized in this paper， including gas flooding and chemical flooding. The research achievements and practices of various technologies in different reservoirs were introduced，and the understanding and development direction of EOR in Zhongyuan oilfield was pointed out. It provided reference for the development of EOR technologies in high temperature and high salt reservoirs at home and abroad.
