- 磨刀门水道水平定向钻穿越工程采用世界先进导向孔对接技术,同时采用了交流线圈铺设新方法、超长距离套管安装新技术、泥浆对注法、安装喷浆短节、深层搅拌桩法加固钻机地锚等,于2008年1月13日回拖成功,创造了新的水平定向钻穿越长度世界纪录(2630m),在超长距离软地层穿越及长距离套管安装技术方面取得了突破。
The advanced pilot-hole interconnection drilling technology in the world was used in Modaomen River horizontal directional drilling （HDD） crossing project, also some new methods such as laying AC coil,ultra-long casing installation, pumping mud from both sides, installing mud jetting sub and using deep mixing piles for anchor consolidation were applied. Modaomen River HDD project was completed on Jan. 13 th, 2008. It created a new world record of HDD length （2 630 m）, and also made a breakthrough in HDD crossing through ultra-long distance soft stratum and long distance casing installation.2008,6(6): 38-39 收稿日期：2008-1-18分类号：P332作者简介：尹刚乾（1968-），男，陕西咸阳人，高级工程师，1991 年毕业于中国石油大学（华东），一直从事水平定向钻穿越施工和管理工作。
