    bwin下载地址建设优化泥浆工艺 顺利完成西安市长安区某小区“一拖六孔”电力管道定向钻穿越工程

    时间:2018-12-20    点击量:245次

    12月16日,随着钻机的强劲引擎在西安市长安区某小区路面破土而出,陕西bwin下载地址建设成功完成了该小区6孔200MPP电力管道定向钻穿越工程。实现了bwin下载地址在定向钻领域的重要突破。

     长安区某小区定向钻穿越工程,设计穿越管段实际水平长度66米,需要在同一个导向孔内敷设6条电力管线,被称为“一拖六孔”。bwin下载地址建设施工班组为了工程顺利开展,采取措施,打两钻,分别拉3孔。

     难度更大的是,在勘察深度范围内,此次穿越段地层全为沙层,而沙层在定向钻施工中是比较难穿越的地层。穿越沙层时经常会遇到塌孔、抱钻、导向抬头等各种困难。在本次施工中,bwin下载地址建设施工班组克服困难积极应对,优化泥浆工艺,增强泥浆造壁、护壁的效果,从而有效的减缓了孔内塌孔现场,顺利完成了定向钻穿越工程施工,并积累了丰富的经验。

     通过此次施工我们总结出,在实际定向钻穿越工程施工中,人们无法改变沙的物理力学性质,但通过对泥浆黏度的调配和泥浆压力的调整可以达到稳定孔壁的要求。
