| 摘 要： | 在定向井的斜井段进行开窗侧钻时，可利用开窗点的原方位作参照物来修正有磁环境对磁力测斜仪的干扰，从而用磁力测斜仪来代替陀螺测斜仪进行开窗定向。江苏油田真１４８井的钻井实践证明，利用该方法不但能提高定向准确性而且可降低侧钻成本。

| Abstract: | When sidetracking at slant intervals in directional wells,the effect of magnetic field on magnetic inclinometer can be corrected by use of ″windows″ original orientation as reference,thus gyroscpic inclinometer was replaced with magnetic inclinometer to sidetracking.Applications at Zhen 148 Well in Jiangsu Oilfield illustrated that the method not only improves orienting accuracy but also cuts down sidetracking cost. |
