摘要： A downhole tool includes a setting cone having a body including an outer surface. The body has a first end, a second end and an intermediate portion. At least a portion of the body includes a taper at the second end. A passage extends through the body from the first end to the second end. An anchor is arranged at the second end. The anchor includes a first end section receptive of the setting cone and a second end section. A mandrel extends through the passage of the setting cone and the anchor. The mandrel includes a first end portion, a second end portion and an intermediate section. A bottom sub is arranged at the second end section of the anchor. The bottom sub includes a first member fixedly mounted to the mandrel and a second member that is shiftable relative to the mandrel.

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： A frac plug system, downhole tool and method of securing a frac plug system in a wellbore in a formation. A mandrel includes a first end and a second end. A setting assembly is coupled to the mandrel at the first end, and an anchor is arranged at the second end of the mandrel and receptive to the setting assembly. The anchor is settable to engage the wellbore. A bottom sub is arranged at the second end of the mandrel and includes a first member movable relative to the mandrel. A gas generates a pressure to shift the first member along the mandrel to move the anchor against the setting assembly, securing the setting assembly in the wellbore via radial deployment of the anchor. The mandrel is separated from the bottom sub to leave the setting assembly and the anchor in the wellbore.

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.
