重复压裂用转向剂的研究及应用进展

Progress on Research and Application of Temporary Diverting Agent for Refracturing

随着储层改造增产的需求日益紧迫,重复压裂用转向剂的研究也逐渐趋于多元化,不同类型的转向剂应运而生。目前关于转向剂的研究主要集中于提高封堵能力、扩展应用范围和降低储层伤害三个方面。文中结合国内外研究现状,对具有自清洁能力的可降解转向剂及应用较为广泛的交联型转向剂进行了重点论述,认为响应国家的绿色发展理念的可降解转向剂是今后的主要研究方向。

With the urgent demand for reservoir stimulation,researches on diversion fracturing agent gradually become diversified,and various types of diverting agents emerge as the time requires. At present,the relevant research focuses mainly on improving the sealing capacity,extending the application range and reducing reservoir damage.Combined with the current situation at home and abroad,biodegradable diverting agents with self-cleaning ability and the more widely used crosslinking diverting agents were focused on. It was believed that the biodegradable diverting agent responded to the national green development concept was the main developing agent direction.
