    摘要: A pressure actuated jarring apparatus includes a tubular housing, a piston, a spring element, and a seat. The tubular housing has a passage therethrough extending from an upper end to a lower end. The piston is disposed within the central bore and is movable axially between an inactivated state and an activated state. The spring element is configured to store energy to drive the piston from the activated state. The seat is coupled to the piston such that when a plug is seated in an orifice of the seat fluid is prevented from flowing through the orifice. The jarring device is fired by increasing pressure in the passage until the plug is forced through the seat, thereby releasing the energy in the spring element and driving the piston from the activated state so that it impacts an abutment and generates a jarring force.

    摘要: A mechanically activated bypass valve apparatus for allowing fluid being pumped through the pipe or coiled tubing string to be bypassed around a tool string and into the wellbore. Activation of the bypass valve is accomplished by applying weight-on-bit to the apparatus to shear a set of shear screws, allowing the mandrel to move axially relative to the tubular housing. Lowering the pipe string and setting down weigh on bit misaligns fluid bypass ports in the mandrel and housing, thus forcing fluid to continue to flow through the bore of the tool and to the toolstring below the bypass tool. Picking up on the pipe string aligns corresponding ports in the mandrel and housing and allows fluid to flow from the bore of the tool to the wellbore annulus, thus bypassing other tools downhole of the apparatus.

    摘要: An apparatus for creating vibrations in a pipe string is disclosed. The device comprises a fluid pump which pumps fluid within a first fluid bore and is connected to the pipe string. A hydraulic pump pumps fluid within a second fluid bore and a movable plunger disposed between the first fluid bore and the second fluid bore intermittently opens and closes access to a tank based on changes to a pressure of the fluid pump. The tank for collecting at least a portion of the fluid is connected to the apparatus via the first fluid bore, and the movement of the plunger is configured to generate vibrations within the pipe string by altering the amount of fluid allowed to flow to the tank.

    摘要: A pressure bleed-off system. The system includes a fluid bypass line having an inlet and an opposing outlet, wherein the inlet is in fluid communication with a high pressure frac line for a hydraulic fracturing operation. The system also includes a high-pressure transducer located proximate the fluid inlet, a first plug valve residing along the fluid bypass line, and a first electric actuator residing on the first plug valve. The actuator is configured to rotate the first plug valve between close and open positions in response to command signals from a controller. The controller, in turn, sends the command signals in response to control signals delivered by an operator, remotely. Preferably, the command signals are wireless signals sent from outside of the red zone. The system may also include a second plug valve along the bypass line.

    摘要: A tool for running a casing string assembly into a wellbore includes a degradable plug assembly that temporarily isolates light fluid trapped in a lower portion of the casing string from heavier fluid in the upper portion of the casing string, thereby reducing the horizontal weight of the casing string by an amount sufficient to overcome a drag force. After the casing string is landed at a final location in the wellbore, fluid is introduced to the degradable plug assembly to degrade the plug and clear the axial passageway of the casing string so that tools or other equipment can pass therethrough.

    摘要: A venturi jet basket assembly adapted to be coupled to a tubing that extends into a wellbore includes a body and a jet nozzle subassembly. The body includes a wall that defines a passageway that extends longitudinally through the body. The body also includes an opening extending through the wall and into the passageway. The wall also includes a flute formed in an outer surface of the wall of the body. The flute is in fluid communication with the opening. The jet nozzle subassembly is disposed within the passageway and includes a jet nozzle. The jet nozzle is arranged to direct fluid received through the tubing through the opening and into the flute such that the fluid is guided into the wellbore by the flute.

    摘要: A pressure activated cyclical valve assembly includes a first sub, a second sub, a piston, and a biasing member. The first sub has a first passageway therethrough. The second sub is coupled to the first sub and has a second passageway therethrough. The piston is positioned within the second passageway and is shiftable between a deactivated position in which a bypass port is closed and an activated position in which the bypass port is open. The piston has a piston orifice and the first passageway is in fluid communication with the second passageway through the piston orifice. The biasing member exerts a force against the piston to maintain the piston in the deactivated position. The piston orifice is sized to restrict the flow of fluid therethrough such that the piston can be shifted between the deactivated and activated positions by changing flowrate of fluid in the first passageway.
