摘要
邻井间最近距离的描述与计算方法已广泛应用于防碰、中靶、轨迹监测与控制,以及对实钻轨迹的质量评价等方面。阐述邻井间最近距离的计算原理、扫描图的绘制方法,并将球面坐标形式的最近距离扫描图分解为以2个极坐标形式表示的平面图,从而实现了视图的科学性、完整性和实用性。还用实例验证了理论的正确性。
The description and calculation of minimum distance between adjacent wells are widely applied to preventing the collision of any wellbore near to it,hitting the target of a rescue well or a directional well,monitoring and controlling a wellbore trajectory, evaluating the quality on an actual surveyed trajectory, etc. This paper describes the calculation principle of minimum distance and the method of drawing its scanning charts. A scanning chart of the minimum distance showing in spherical coordinate system is resolved into two plane figures with polar coordinates. As a result, this kind of view is proved to be scientific,integral and practical. At length,an example is given to test and verify the theory presented in this paper.
