随着油田勘探开发过程的进行,钻井、固井、射孔、修井等各种措施都有可能对油层造成伤害,导致油层堵塞。因此,有关油气层保护的问题日益引起各界的重视,围绕如何解堵成为油田开发中的一项重要研究内容。本文总结了瓦窑堡油田油井解堵技术机理及应用现状,并给出了建设性建议。 With the progress of oilfield exploration and development, various measures such as drilling, cementing, perforation and workover are likely to cause damage to the oil layer, resulting in blockage of the oil layer. Therefore, the protection of oil and gas reservoirs has drawn increasing attention from all walks of life, and has become an important research topic in the field of oilfield development. This paper summarizes the technical mechanism and application status of oil well plugging in Wayaobao Oilfield and gives constructive suggestions.
