摘要
通过建立井身轨迹数学模型,采用平均角法进行程序设计,计算出垂深、地下坐标、狗腿等数据,得到井身的变化规律。主要结论为:采用该数据模型,提高了程序的运行效率和井身精度;采用该方法得到的井身轨迹资料更符合实际,提高了钻井的准确性。
This paper expresses the change regulation of directional well track by establishing a mathematical model of well tracks and adopting the average angle method to program out true vertical depth, bottom coordinates and dogleg angle. It is concluded that the programming efficiency and well track accuracy are both improved by using this mathematical model. The data of well tracks obtained by adopting this method are more realistic and the drilling accuracy is thus improved.
