一、问题的提出井眼轨迹控制是走向井的一项重要技术。从50年代至今国内外钻井界在这方面做了大量研究，取得了许多研究成果。以往所建立的及关于影响并眼轨迹的模式中，均未将底部钻具结构特性作为一个独立的因素加以考虑，因此使得预测效果不够理想。本文通过并眼见何形状、 First, the question raised Well trajectory control is an important technology to the well. Since the 1950s, domestic and overseas drilling communities have done a lot of research in this field and have made many achievements. None of the previously established models of impact and eye trajectory models considered the bottom hole assembly structural characteristics as an independent factor, thus making the prediction less than ideal.
