摘要： A valve for use in a tool positioned in a well that includes a body having a bore and a port connected to permit fluid communication between the well and the bore. A piston is supported in the body for movement between an open position to open the port and a closed position to close the port. A rupture disc is responsive to fluid pressure in the well and ruptures when a predetermined pressure is applied so that fluid pressure is communicated to the piston to move it from the closed position to the open position. A lock member secures the piston in the closed position after the piston moves from the open position to the closed position.

摘要： A packer for use inside a casing of a subterranean well includes a resilient element, a housing and a rupture disc. The resilient element is adapted to seal off an annulus of the well when compressed, and the housing is adapted to compress the resilient element in response to a pressure exerted by fluid of the annulus of a piston head of the housing. The housing includes a port for establishing fluid communication with the annulus. The rupture disc is adapted to prevent the fluid in the annulus from entering the port and contacting the piston head until the pressure exerted by the fluid exceeds a predefined threshold and ruptures the rupture disc.

摘要： A plug for actuating a movable member of a device in a wellbore includes a housing adapted to be lowered into the wellbore and a seal member mounted on the housing. The seal member is arranged to engage the movable member such that a pressure applied to the first end of the housing moves the housing and the movable member. A chamber is provided in the housing, and a pressure responsive member at an inlet end of the chamber permits fluid communication with the chamber when the pressure applied to the first end of the housing reaches a predetermined pressure.

摘要： A regulation mechanism configured to automatically close off fluid flow through a line based on flow rate exceeding a predetermined level. This mechanism may be particularly beneficial when employed in conjunction with downhole chemical injection systems that are directed at well locations prone to becoming low pressure in nature. That is, in a conventional system, once the inherent pressure at the downhole end of an injection line exceeds that of the adjacent downhole environment, the flow rate of the column of fluid in the line may naturally increase as chemical is unintentionally emptied into the well. However, use of embodiments of the flow-based regulation mechanism detailed herein may near-automatically prevent such undesirable emptying of chemical into a low pressure well.

摘要： A technique that is usable with a well includes deploying a plurality of location markers in a passageway of the well and deploying an untethered object in the passageway such that the object travels downhole via the passageway. The technique includes using the untethered object to sense proximity of at least some of the location markers as the object travels downhole, and based on the sensing, selectively expand its size to cause the object to become lodged in the passageway near a predetermined location.

摘要： A retrievable flow control device comprising a housing configured to sealably couple with a completion component. The housing may comprise a first port and a second port establishing a fluid pathway. The fluid pathway may regulate a fluid flow as the fluid flow passes through the fluid pathway. The housing may further comprise a coupling mechanism configured to releasably couple with a corresponding feature of the wellbore completion. The downhole flow control device may be configured to be retrievable independently of the completion component. The flow control device may comprise a check valve in the fluid pathway in order to substantially constrain the fluid flow to a single direction. In some cases, the flow control device may be configured to couple with a side pocket. In other cases, a concentric flow control device may be configured to couple with a screen base pipe, tubing, or stinger.
