摘要
SZ型水压自动定向仪是无缆式的,有外径54、73mm两种,适用于深孔和钻孔顶角≥4°的斜孔,以及高固相冲洗液钻孔。该仪器定向过程简单,定向一次只需3—10min,定向精度为(±10°)。同时还介绍了定向仪的结构及维护保养。
: The wireless SZ automatic hydraulic orientator, with outside diameter of 54 mm or
73 mm,is applicable to deep hole and inclined hole with an angle of≥4°, as well as holes with high
solid drilling fluid. Simple to operate, it takes onIy 3 to 10 minutes to finish one orientation, with
a precisely directional orientation of ± 10°. The structure and mantenance of the orientator are also
