钻孔偏斜钻孔偏斜hole deviationzuankong Planxie钻孔偏斜(hole deviation)工程钻探中，钻孔的实际轴线偏离设计轴线的现象。这又称钻孔弯曲。钻孔设计轴线在地下空间的坐标位置，是根据工程的不同要求确定的。由于地质和钻探工艺技术方面的原因，钻孔的实际轴线不可避免地会偏离设计轴线。各类不同用途的钻孔允许的偏斜量不尽相同，如工程地质勘察孔每IOOm间隔的偏斜量，垂直孔不得超过1.5“，斜孔不得超过3o;桩基孔的偏斜量，限在不超过孔深的1%内。钻孔偏斜超限会降低地质资料的可靠程度，降低工程质量，并给正常钻进造成困难，甚至酿成孔内辜故。钻孔偏斜时，需及时进行钻孔偏斜测量，准确了解钻孔空间位置，采取有效措施预防并及时纠正钻子L偏斜。钻孔偏斜测量测量钻孔某点顶角、方位角的作业。这又称钻孔弯曲测量，简称测斜。测量钻孔偏斜的仪器称测斜仪。测斜仪种类繁多，且发展很快。测斜仪一般由测顶角和测方位角两部分组成，其中测顶角部分利用液面水平原理或重锤原理工作;测方位角部分利用地磁场定向、间接定向或陀螺定向原理工作。工程钻探中，还经常用氢氟酸法测斜，但只能测量钻孔顶角。其方法是将按比例配制的氢氟酸水溶液注入壁厚3mm、直径27~3omm、长200~25omm的玻璃管内，上口用胶塞塞紧后，放到特制的测斜接头内下到拟侧斜孔段，停留一段时间后提升钻具取出玻璃管，量测玻璃管内的蚀痕并计算钻孔顶角。孔深在3om以内的大口径孔，亦可采用孔口十字架配合重锤进行孔斜测量。防斜措施钻探施工中，为预防钻孔发生偏斜而采取的措施。一般有:(l)确保设备安装质量;(2)采用合理的钻进工艺、钻具结构和钻进参数;〔3)根据地层自然弯曲规律设计钻孔;(4)钻进中按照规程要求及时测斜。钻孔稍有偏斜及早纠正，严防其发展。纠斜措施钻孔偏斜量超过允许限度时采取的使钻孔偏回设计轴线的措施。常用的有自然纠斜法、反转纠斜法、扩孔纠斜法、回填原孔法和导斜器纠斜法等。(l)自然纠斜法。用于纠正钻孔顶角偏斜，从对孔内钻具的受力分析出发，改变钻具结构方式，如使用大钻头配小一级岩心管的塔式钻具、连接支撑接头或偏重管等，使钻具工作时在钻头上产生一矫正力，促使钻进过程中钻孔顶角增大或减小。(2)反转纠斜法。利用钻具反方向回转钻进来改变钻具的偏斜力和钻粒对钻具的楔垫作用，达到纠正钻孔的方位偏斜的目的。(3)扩孔纠斜法。用比偏斜孔段钻孔直径大一级的钻具配长岩心管，从矫直孔段向下扩孔钻进，使偏斜孔段通过扩壁纠直。(4)回填原孔纠斜法。向偏斜孔段灌注水泥，待凝固后用长度较大、刚性较好的钻具钻出新孔。(5)导斜器纠斜法。向钻孔内定向下入导斜器，强制纠正偏斜钻孔的顶角和方位角(见定向钻探)。
