| 中文摘要:确定钻孔轨迹是分析处理钻孔偏斜问题的前提。将测斜参数中的孔深s作为变量，用多项式函数逼近的方式建立钻孔轨迹的参数方程，推导了确定钻孔轨迹空间位置的数学模型，通过算例表明模型有较好的精度。 |

| Abstract:Determining the borehole trajectory is the premise of analyzing and correcting drilling deviations. Taking the borehole depth s measured during inclination survey as the variable, this paper establishes a parameter equation for the borehole trajectory with polynomial fitting, and a new mathematical model for the 3D borehole trajectory is therefore deduced. Calculations demonstrate that the new model gives better accuracy. |
