    摘要： A system for disassembling a drill assembly including a drill bit and one or more columns interlinked with each other. The system includes a first clamping mechanism adapted to engage one of the drill bit or a first column, and a second clamping mechanism adapted to engage a second column disposed successively to the drill bit or the first column. The second clamping mechanism is turned relative to the first clamping mechanism to at least partially delink the second column from the first column or the drill bit. The system further includes a first actuator adapted to move one of the first clamping mechanism or the second clamping mechanism relative to the other to define a gap therebetween to reveal an interface between the second column and the drill bit or the first column for delinking the second column relative to the drill bit or the first column.

    摘要： The invention provides a bit breaker comprising a plate that bounds a pipe slot. The bit breaker has two jaws that define two working surfaces located on opposite sides of the pipe slot. The two jaws are configured to move relative to the plate. In some embodiments, the invention is an assembly that further includes a pipe, tool section, tool or pipe joint received in the pipe slot. The pipe, tool section, tool or pipe joint has formed therein two crosswise grooves located on opposite sides of the pipe, tool section, tool or pipe joint. In some embodiments, the plate defines two fixed arms and a fixed base leg, with the two jaws mounted respectively against the two fixed arms. The bit breaker can have an adjustable arm such that the pipe slot can be surrounded about 360 degrees by the bit breaker.

    摘要： A method of connecting a downhole tool and a downhole tubular: positioning the downhole tool coaxially on a rotatable seat; and rotating the seat to thread the downhole tool to the downhole tubular. A support stand: a structural frame with ground engaging members; and a downhole tool seat mounted for rotation on the structural frame about an axis of rotation, the downhole tool seat being coaxial with the axis of rotation. A combination of the support stand of and a downhole tool on the seat.
