使用铅锤测斜仪和测角器来测量鑽孔弯曲度时,往往由于仪器欠灵、操作欠熟练而造成误差。为此,我们采用了氢氟酸测斜仪,并在实验中摸索到一种量度的方法。其特点是量度快,较准确。首先,将欲测之玻璃试管置于一平向上,与直立缩尺(其比例尺为1:100)平行靠近,一手把住缩尺不要摇晃,一手把住试管左右转动几周,以找出试管 When using a plunge inclinometer and goniometer to measure the curvature of a borehole, errors often result from under-appli- cation, under-profiling operations. To this end, we used hydrofluoric acid inclinometer, and in the experiment found a way to measure. It is characterized by rapid measurement, more accurate. First of all, the glass tube to be tested is placed flatly and horizontally, and the upright scale (the scale of which is 1: 100) is placed in parallel. The scale should not be shaken in one hand and the right and left of the tube should be rotated for several weeks in one hand to find out the tube
