    摘要: A plug releaser includes, a first tubular with at least one first port through a wall thereof, at least two plugs sealingly engaged with the first tubular defining a first chamber between the first tubular and the at least two plugs. The at least two plugs are rupturable or releasable from the first tubular at selected pressure differentials thereacross, and a second tubular is in operable communication with the first tubular at locations beyond the at least two plugs. The at least one first port provides fluidic communication between the first chamber and an outside of both the first tubular and the second tubular and the at least one first port is sized to prevent pressure differential across the at least two plugs from building to a selected pressure differential needed to rupture or release the plugs in either direction for at least a period of time.

    摘要: A tubular occlusion and pressure damping system includes, a tubular, an occlusion configured to block flow through the tubular, the occlusion having, a first chamber in pressure communication with an inside of the tubular, a second chamber in fluidic communication with the first chamber, and a flow restrictor in operable communication with the first chamber and the second chamber. The flow restrictor configured to throttle flow between the first chamber and the second chamber such that pressure increases within the second chamber lag behind pressure increases in the inside of the tubular at least until the second chamber has reached a selected volume after which pressure within the second chamber increases toward the pressure in the inside of the tubular.

    摘要: An apparatus for generating power includes a fluid chamber configured to receive borehole fluid, one or more conductive coils surrounding the fluid chamber, a reciprocating magnetic shuttle disposed in the fluid chamber and dividing the fluid chamber into a first volume and a second volume, a first conduit connected to the first volume, and a second conduit connected to the second volume, the first conduit and the second conduit extending from a tubular conduit to an annulus. The apparatus includes a switching assembly configured to alternate between a first operating state where the first volume is in fluid communication with the annulus and a second operating state where the first volume is in fluid communication with the tubular conduit, to alternate a direction of differential pressure between the first volume and the second volume and cause the magnetic shuttle to move in a reciprocating motion and generate an electric current.
