TC-938堵剂在任平2井堵漏中的应用

APPLICATION OF TC-938 PLUGGING AGENT IN LOSS CIRCULATION CONTROL OF WELL RENPING-2

    摘要
  • 摘要: 灰岩油藏,尤其是处于风化壳部位的灰岩油藏孔缝洞发育,钻井过程中钻井液漏失现象严重,会导致无法钻进或卡钻恶果。根据任平2井所在的储层特点和钻达3347~3390m井漏段,采用有机化学堵剂工艺技术较圆满地解决了这个问题。介绍了TC-938化学剂及凝胶的性能,堵漏原理及在该井的现场应用,通过堵漏工艺技术分析看出应用化学剂堵漏工艺技术在任平2井的水平段堵漏施工十分成功,并取得了理想的效益。认为这是促进整体钻井工艺技术水平的一项新技术,值得推广。

     

    Abstract: This paper introduces a practice that water shutoff agent TC-938,an organic compound,is successfully used as a loss circulation material in Well Ranping 2 for loss circulation control of carbonate reservoir.The characteristics of the chemical agent TC-938,plugging mechanism and applied technology are indicated in the paper.It is believed that this practice is a new drilling technology and valuable to develop and apply in loss circulation control.
