一种对付特大井漏的钻进工艺

TECHNOLOGY TO DEAL WITH SERIOUS LOST CIRCULATION

    摘要
  • 摘要: 川东地区碳酸盐岩高陡构造,地层压力系统复杂,不可预见性高,井漏频繁,在每年的钻井工作中都要付出很高的代价。近几年来随着综合治漏措施的完善,治漏成功率逐年提高。但目前对于长段易塌裸露层的特大漏失,尚无一套根本的处理办法。通常采用降密度和堵漏措施,但成功率很低。若用清水强钻,则易造成井塌甚至报废。本文以门西2井为例,介绍对付此类漏失的全新工艺。

     

    Abstract: The lost circulation often happen in carbonate with high steep structure in east area of Sichuan during drilling Because of water,then wall sloughing will apped which made well abandoned.This paper take Menxi 2 well as an example to introduce a new technology to treat lost circulation.
