注水井复合解堵技术研究与应用

Research and Application of Composite Plugging Technology for Water Injection Wells

石油作为主要的能源之一,由石油提炼出的副产品如塑料等与人们的生活息息相关。为了提高采油效率,目前经常使用注水开发油田技术,但在一些渗透性较低的油藏储层中,存在物性较差的问题,容易导致地层堵塞的问题。针对这一问题,根据文献以及实践经验从多个方面阐述了目前国内外所采用的多种解堵措施。

As one of the main energy sources,petroleum by-products such as plastics are closely related to people’s lives.In order to improve oil recovery efficiency,water injection technology is often used to develop oilfield technology,but in some reservoirs with low permeability.Among them,there is a problem of poor physical properties,and thus it is easy to cause a problem of clogging of the formation.In response to this problem,based on the literature and practical experience,the various deblocking measures adopted at home and abroad are described in many aspects.
