钻孔轴线空间曲线方程的建立及探讨

为了提高钻孔测斜数据的处理精度，提出钻孔的方位角及倾角在相邻测斜点之间是均匀变化的假设。以微积分学为工具，推导出钻孔轴线空间参数方程及其在平、部面上的投影方程；以实例对现行的数据处理方法所得结果和按曲线方程处理所得结果进行比较，认为该种处理方法比较接近实际情况，同时能为自动绘图提供方便。

Formation and discussion of drilling oxial space curve

To improve the treatment precision of the date from drilling inclinometry. A presumption is put forward that drilling bearing and dip angle vary evenly between the adjacent points of deviational survey. By infinitesimal calculus,the parameter equation and projection equation in plane and profile are calculated. According to the comparison with the results from date treatment in the present method, the curve equation method is considered more available for the present situation. More over, it supplies convenient for auto drawing.
