油田注水开发后期提升采收率的技术措施浅析

Technical Measures for Improving Oil Production Rate in the Later Stage of Oilfi eld Water Injection Development

在油田逐步开发和产量下降的背景下,注水开发成为提高油田采收率的重要方法。然而,注水开发后期由于油井的汇水压力下降、水体渗透能力不均匀等因素影响,采收率下降的问题越发突出。基于此,本文旨在研究油田注水开发后期提升采收率的创新技术,包括微生物采油技术(MEOR)、化学复合驱、空气驱等,研究结果表明通过这些技术的应用可以有效提升油田注水开发后期的采收率。

Under the background of gradual development and production decline of oilfields,water injection development has become an im-portant method to improve oil recovery rate in oilfields.However,in the later stage of water injection development,due to the decrease in the catch-ment pressure of oil wells and the uneven permeability of water bodies,the problem of oil recovery rate decline has become more and more prominent.Based on this,this paper aims to study the innovative technologies to improve the oil recovery rate in the later stage of oilfield water injection develop-ment,including MEOR technology,chemical composite flooding,air flooding,etc.,and the results show that the application of these technologies can effectively improve the oil recovery rate in the later stage of oilfield water injection development.
