两井定向内业计算的新方法及其应用

New Method for Calculating Two Well-oriented Internal Operation and Its Application

现有文献中两井定向内业计算的3种方法存在不足,为此,采用1种新方法——附有虚拟观测值的条件平差法来消除井下连接测量误差的影响,达到提高两井定向成果解算精度的目的,并用实例验证了新方法的正确性。

In view of the insufficiency of the three methods for the calculation of two well-oriented internal operation that are reported in the literature available, a new method virtual observation value-added conditional error balancing method, is used to eliminate the effect of underground connection measurement error so as to raise the calculating accuracy of two well-orientation results. The correctness of this new method is verified with real cases.
