摘要： A setting tool assembly configured to couple with a part of a workstring, the assembly having an inner housing coupled with one or more other components. A trigger device is coupled with a movable piston. During run-in, the piston is in a first position. Upon activation, the trigger device undergoes an altering event whereby the piston moves to a second position as a result of a pressure acting thereon.

摘要： A downhole tool having a mandrel, and a bottom slip disposed around the mandrel. The bottom slip includes a circular body having a one-piece configuration characterized by a plurality of slip segments by at least partial material connectivity therearound. The bottom slip is made of a filament wound composite material, which means the bottom slip has a plurality of layers joined by respective interface layers. An outer slip surface of at least one of the plurality of slip segments is defined in cross-section by a plane P that intersects a longitudinal axis of the downhole tool at an angle a1 when the bottom slip is in an unset position.

摘要： A downhole tool having a mandrel, a first slip, a second slip, a lower sleeve, and a tethered ball assembly. The mandrel includes a proximate end; a distal end; a bore having a ball seat associated therewith; and an outer surface. The first slip is disposed around the mandrel. The second slip is disposed around the mandrel. The lower sleeve is proximate to the first slip, and engaged with the outer surface at the distal end. The tethered ball assembly includes a ball; a drag; and at least one tether coupled between the ball and the drag.
