钻孔弯曲度是岩心钻探工程六项质量指标之一。这项指标直接影响到钻孔穿矿部位的空间座标和矿体的形态问题。钻探工程是按照地质设计进行施工的，施工的结果应该达到地质工作的要求。但是在钻探施工过程中，由于地质和工艺技术方面的因素，钻孔顶角、方位角往往会发生变化，钻孔向不同方向弯曲，从而造成钻孔不同程度的偏离原设计的位置。钻孔弯曲既然目前还不能完全避免，弯曲的程度
Drilling curvature is one of the six quality indicators of core drilling engineering. This indicator has a direct impact on the spatial coordinates of boreholes and the morphology of ore bodies. Drilling engineering is carried out according to geological design, the result of construction should meet the requirements of geological work. However, due to geological and technological factors, drilling apex angle and azimuth often change during the drilling construction process, and the bored holes bend in different directions, resulting in different degrees of deviation from the original designed positions. Since the bending of the drilling can not be completely avoided at present, the degree of bending
