摘要： A disposable setting tool includes a housing having a first end, a second end, and an intermediate portion having an outer surface and an inner surface defining a passage. A piston assembly is arranged in the passage. The piston assembly including a first piston portion and a second piston portion that extends axially outwardly of the second end of the housing. The first piston portion includes a first end portion, a second end portion, and an intermediate section having an outer surface portion and an inner surface portion that extends between the first end portion and the second end portion. The inner surface portion defines a pressure passage. An atmospheric chamber is defined between the inner surface of the housing and the outer surface portion of the piston assembly.

摘要： A frac plug system downhole tool and method of securing a frac plug system in a wellbore. A mandrel extending from a first end to a second end. A setting assembly is on the first end of the mandrel and is movable along the mandrel. An anchor is at the second end of the mandrel and is expandable to engage the wellbore. A gas generates a pressure to move the setting assembly along the mandrel to expand the anchor at the second end of the mandrel.

摘要： An apparatus for setting a plug in a borehole penetrating a subsurface formation includes a tool mandrel defining a chamber having a port and a power charge disposed in the chamber for emitting a pressurized gas upon ignition. The apparatus also includes an outer sleeve at least partially surrounding the tool mandrel and defining an annulus between the outer sleeve and the tool mandrel where the annulus is in communication with the port. The apparatus further includes a piston disposed in the annulus and having an outer surface facing uphole within the annulus, the piston being in mechanical communication with a setting sleeve of the plug, wherein displacement of the setting sleeve causes setting of a slip and a seal of the plug.
