保証鑽孔倾斜方位滿足地質設計要求,这是鑽探工作中一項重要任务。尤其在斜孔鑽进时,弯曲情况更不易控制。往往由于操作方法不当而产生鑽孔弯曲过大或过小的現象。此时,即需根据鑽孔弯曲情况进行人工导斜的工作,以加以补救纠正。現將401队519机使用偏心楔子进行鑽孔人工弯曲的經驗。 Ensuring that the borehole tilt orientation meets the geological design requirements is an important task in drilling. Especially when drilling a slant hole, the bending condition is more difficult to control. Often due to improper operation method resulting in drilling bending is too large or too small phenomenon. At this point, the need to manually bend according to the situation of drilling guidance work to be remedied. 401 team 519 now use eccentric wedge drilling artificial bending experience.
