摘要
文章从有代表性的井喷事故井的发生及危险井的治理过程分析了从溢流到井喷发展的几个阶段,强调了防止井喷要分别重视的发现溢流、关井、压井三个环节及各环节要把握的技术要点,强调了要根据溢流的动因把握观察、发现溢流的关键时机,根据不同的动因重建井底压力平衡应采取的压井方法;还分析了国内外现用的几种关井方法的优缺点,提示了选择的关井方法应适应"快"的要求。
According to the occur of well blowout and treatment of dangerous well,the paper analyzed the several phases from overflow to well blowout,emphasized the technical points of prevention well blowout,i.e.recognition overflow,well shut-in and well killing links.The paper analyzed the moment of truth of discover overflow based on the features of overflow,and presented the adopted well killing methods because of reintegration downhole pressure balance.At the same time,the relative merits of typic well shut-in methods were also analyzed.
