初级定向钻探是利用钻孔自然弯曲规律的定向钻进技术。在野外如何利用小型电算器使钻孔弯曲计算结果越来越接近于钻孔在空间的实际位移状态,至为重要.兹介绍我队实际工作中所用的计算方法如下。一变角法与移位法测斜计算特点初级定向孔利用“变角法”和“移位法”钻进,对钻孔弯曲测量要及时、准确、计算严格才能掌握钻孔实际所“行走”的空间位置,以决定在施工中是否采用保斜、造 Directional drilling is the use of primary directional drilling natural curvature of the directional drilling technology. How to use the small electric calculator in the field to make the calculation result of drilling bending more and more close to the actual displacement status of the drilling hole in space is of great importance. A variable angle method and shift method Inclination calculation characteristics Primary orientation hole using the “variable angle method” and “shift method” drilling, drilling bending measurement to be timely and accurate, rigorous calculations to master the actual drilling “walking ”The location of the space to decide whether to use Paul in construction, made
