摘要
为了研究油田开发过程中的各种油层伤害问题 ,通过分析油田开发中存在的油层伤害的各种类型和机理 ,对钻井、完井、生产、修井、二次采油、三次采油、增产增注措施等各开发阶段各项作业中潜在的油层伤害及解决方法作了系统的总结 ;其次 ,介绍了国内外在该领域内的研究方法、途径、研究现状及新技术的发展状况 .研究表明 :在油田开发过程中 ,油层污染问题是非常普遍的 ;因此在油田开发的各环节 ,采取严格的油层保护措施 ,准确地诊断伤害类型和原因 ,并选取有效的解除油层污染和堵塞的措施 。
Formation damage was divided into six types according to different damage mechanism. The formation damages existing in every stages of oilfield development from drilling, completion, production, workover, secondary recovery, tertiary recovery to various well stimulations, were analysed. The ways and measures were proposed for reducing or eliminating the damages. The authors also introduced the new approaches, present situation and progress in the research of formation damages at home and abroad.
