国外油层保护新措施

NEW MEASURES FOR OIL PAY ZONE PROTECTION IN FOREIGN COUNTRIES

随着科学技术的发展、油田勘探开发的不断深入，油气层保护越来越被广大科研工作者所重视。进入９０年代，油气层保护在国外进展较快，他们试验成功了许多解除地层损害的新方法。本文介绍了国外现阶段所采取的用低聚合物新型粘土稳定剂处理低渗透地层，用超声波解除地层损害等７种防治地层损害新措施。

With the development of scientific techniques and continuous exploration and development of oil fields, hydrocarbon reservoir protection becomes more and more important for scientific researchers. In 1990's hydrocarbon reservoir protection techniques develop quickly in foreign countries, and many new measures to control formation damage have been found. In this paper 7 new measures now used in foreign countries to prevent formation damage are introduced, such as applying new clay stabilizer of low polymer to low permeable formation, and supersonic wave to control formation damage.
