针对极等间距网与笛卡尔坐标在定向瓦斯钻孔中的应用进行了介绍,指出通过极等间距网与笛卡尔坐标相结合绘制的定向瓦斯抽采孔实钻轨迹能够简便,清晰地反映出实钻轨迹与优化设计轨迹的偏差距离,有利于对轨迹的控制及合理优化。%The paper introduces the application of the polar iso-distance and Cartesian coordinate in directional gas drilling,points out the tracks of the directional gas drilling by using the polar iso-distance and Cartesian coordinate are clear,and reflects the deviation distance between the drilling tracks and the optimal design tracks,so it is helpful for the control over the tracks and the reasonable optimization.
