摘要
通过对使用无磁钻铤、常规钻铤和多点测量仪所测得的下套管后井眼井斜和方位变化规律的分析,得出一些有价值的结论,对于修井及套管开窗侧钻具有重要的指导意义。
Some valuable conclusions were madeconcerning the change of deviation and azimuth ofborehole aftr descenting the casing by using non nagnetic drill collar, normal drill collar and multi-shot surveyor, An important instruction was somade for the well repair and casing cut lateraldrilling。
