摘要
论述定向钻技术的适用条件及工艺特点。结合给水管道工程实例,阐述定向钻技术的主要设计参数的选取原则及设计的注意事项、运用效果可供类似工程的设计进行参考。
The applicable conditions and technological characteristics of directional drilling technology are discussed.Combined with water supply pipeline engineering example,this paper expounds the selection principle of main des ign parameters of directional drilling technology and cautions of the design,which can provide references for similar engineering design.
