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。
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.
