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 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 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： 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.

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 downhole tool includes a setting tool having an outer surface, an inner surface defining a passage and a terminal end. An actuator mechanism is arranged in the passage. A setting member is arranged at the terminal end in the passage. The setting member includes a side portion that is angled radially inwardly from a first end portion to a second end portion. A collet member extends over the setting member, and a seal member is operatively connected to the collet member at the second end portion of the setting member.
