利用合理而可靠的测斜仪确定钻孔的方位和倾角,是提高地质勘探质量最重要的指标之一.目前,较完善的全测测斜仪:如包良柯夫测斜仪、定盘测斜仪、?Ⅲ-2型测斜仪等,都能获得令人满意的测量结果.但上述测斜仪很多勘探队没有,同时对仪器的正确使用、维护和测量结果的误差校正,尚存在着一些技术问题.因此,当孔深不大(孔深<200米)和在无须确知钻孔轴线的方位角的情况下, It is one of the most important indexes to improve the quality of geological prospecting by using the reasonable and reliable inclinometer to determine the azimuth and inclination of borehole.At present, Inclinometer, â ... ¢ -2 type inclinometer, etc., can obtain satisfactory measurement results.But many of the above survey team did not have inclinometer, while the correct use of the instrument, maintenance and measurement results of the error correction, yet There are some technical problems.Therefore, when the hole depth is not large (hole depth <200 m) and without knowing the azimuth of the drilling axis,
