    摘要: A pumpdown system for use in performing wireline operations on a well bore includes a wellhead assembly positioned at the top of the well bore, a pumpdown fluid source, a flowline having a first end connected to the pumpdown fluid source and an opposite second end, and a wireline pressure control string releasably connectable to the wellhead assembly. The wireline pressure control string includes a pumpdown sub having a body and a through bore which extends through the body, at least one pumpdown valve having an inlet connected to the second end of the flowline and an outlet in fluid communication with the through bore, and a connector positioned below the pumpdown assembly for releasably securing the wireline pressure control string to the wellhead assembly. In operation of the pumpdown system, the wireline pressure control string is connected to the wellhead assembly and fluid from the pumpdown fluid source is conveyed through the flowline, the pumpdown valve and the pumpdown sub into the well bore.

    摘要: A method includes providing a hydraulic connector having a hydraulic lock, wherein the hydraulic lock is operated using a hydraulic supply line and a hydraulic outlet line, and connecting the hydraulic connector to a component by activating the hydraulic lock. While the hydraulic lock is activated, a connection between the hydraulic connector and the component is pressure tested by directing a portion of the hydraulic fluid from the hydraulic supply line to a pressure testing system, using an intensifier in the pressure testing system to pressurize the portion of hydraulic fluid to a testing pressure, and directing the pressurized portion of hydraulic fluid to the connection to test a pressure rating of the connection.

    摘要: A connecting assembly for connecting a first body and a second body includes a connector having a plurality of segments and a main piston positioned around at least a portion of the connector. The connector includes: a channel that extends longitudinally through the connector from a first end to a second end; a plurality of teeth formed on an inside of the connector near the first end and near the second end; a first jaw formed of at least one teeth near the first end; and a second jaw formed of at least one teeth near the second end and axially spaced apart from the first jaw. Each of the plurality of teeth has a leading side facing an axial center of the connector, a top side, a contact point at a transition between the leading side and the top side, and a trailing side opposite the leading side. The teeth of the second jaw include: a first tooth axially closer to the axial center of the connector than the remaining teeth of the second jaw and an end tooth axially farther from the axial center of the connector than the remaining teeth of the second jaw.
