摘要 |
The present invention provides drilling assembles and methods that are especially useful for a bottom hole drilling assembly for drilling/reaming/or other operations related to drilling a borehole through an earth formation. In one embodiment, the drilling assembly utilizes standard drill collars which are modified to accept force transfer sections. In another embodiment, the drilling assembly comprises a tension inducing sub which creates a force that may be used to place the bottom hole assembly or portions thereof in tension. In another embodiment, a reaming assembly is held in tension to provide a stiffer reaming assembly. |
