| 摘 要： | 对旋转磁场测距导向系统应用于双水平井导向钻井中的工作原理进行阐述,把旋转磁短节看成旋转的磁偶极子,推导旋转磁短节周围空间远场的磁场分布规律,并在此基础上论证探管记录的轴向磁信号两个振幅最大值之间的距离等于双水平井水平段间距,导出根据探管探测的磁信号计算双水平井水平段相对方位的方法。根据测距导向计算方法,利用旋转磁场测距导向系统可以引导正钻井沿着与已钻井水平段平行的路径钻进。

| Abstract: | The operating principle of rotating magnet ranging service system for drilling twin parallel horizontal wells was introduced.The rotating magnetic sub was characterized by a rotating magnetic dipole,and the far magnetic field distribution of the rotating magnetic sub was deduced.According to the far magnetic field distribution of rotating magnetic sub,the conclusion that the distance between the two axial field amplitude maxima equals the separation between the twin parallel horizontal wells was demonstrate... |
