摘要： A tool for selectively treating a wellbore with fluid that includes a tubing string having a sidewall defining an inner bore, the sidewall comprising a flow area having at least one fluid flow port that permits fluid flow through the sidewall. Fluid is prevented from flowing through the flow area when a closure is in a closed position. When in the open position, fluid flows through the flow area. An axial seal is connected to the closure to selectively close the inner bore against fluid pressure to apply the predetermined opening force to move the closure to the open position. A releasable connector connects the axial seal to the closure and a retrieval tool attachment releases the axial seal from the closure upon application of a predetermined release force by a retrieval tool.

摘要： An intermittent lift plunger includes at least one seal mandrel, a bottom sub and an upper valve assembly. The valve assembly is closed by a well bottom stop which inserts into the lift plunger and opened by a lubricator stop at the top of the well. The seal mandrel includes a sleeve seal formed from an elastomeric rubber or plastic, which inflates to engage the well bore surface when the valve is closed and a pressure differential exists.

摘要： A downhole valve for insertion in a production tubing string permits recirculation of fluid pumped into the casing annulus. The valve includes a cylindrical housing defining an opening, an internal mandrel disposed within the housing, defining a central bore and defining an opening, a valve between the housing and the mandrel, wherein said valve opens to allow fluid communication from the mandrel central bore to the annulus space in response to a pressure differential between the mandrel central bore and the annular space, and biasing means for biasing the valve in a closed position. The valve may be set within a completion string by wireline techniques.

摘要： A method and apparatus for centering and engaging a casing against a wellbore. The apparatus comprises a valve body locatable in-line with the casing the valve body having an outer casing extending between first and second ends and a central passage therethrough, and at least one radially movable body extending therethrough. Each radially movable body has an aperture therethrough so as to permit an exterior of the valve body and the central passage to be in fluidic communication with each other. The apparatus further comprises a cylinder and a piston therein operable connected to the radially movable body in selective fluidic communication with the central passage. The method comprises locating the valve body in line with a wellbore casing, pressurizing the casing with a pressurizing fluid and transmitting the pressurizing fluid the cylinder so as to displace a piston located therein and extend the radially movable body.
