查询词典 bore through

In order to tackle the difficulties including the sidetracking, the reentrance of the main hole, the well bore trajectory control, and the poor drillability of the formation, some technologies are put forward, such as the sidetracking technology of compound holes, the pipe string reentrance technology of main holes, the well bore trajectory control technology, and the drilling speed increasing technology. All the technologies have been applied to the field successfully, greatly shortening the drilling cycle and guaranteeing the safe and fast completion of the well.
