| 摘 要： | 根据张力样条的特性及定向井井眼轨迹的形成规律,提出了用张力样条模拟定向井井眼轨迹的方法.详细介绍了用张力样条法确定定向井井眼轨迹的步骤.利用这种方法可以计算定向井任一点的空间位置.实例计算结果表明,在已知任意个相邻测点之间,用张力样条插值计算未知测点的井斜角和方位角,与实测值相比,误差很小,满足实际井眼轨迹计算的要求,具有实用价值,为定向井井眼轨迹的计算提供了一种新的方法. |

| Abstract: | Based on the characteristics of the tension spline technique and the formation law of the directional well trajectory,it is proposed that the tension spline technique is used to simulate directional well trajectory.The steps of using the tension spline technique to determine the directional well trajectory are introduced in detail.And the coordinates of any point in a directional well trajectory can be calculated using this technique.The deviation angle and azimuth angle of a point between any two known adjacent points in a well trajectory can also be calculated,and the calculation error is very small.The obtained results agree with measured figures in field fairly well.So this method provides a new approach for the calculation of directional well trajectory. |
