摘要： An injection valve including a primary valve having a flapper, a flapper seat configured to seat the flapper, and a flow tube disposed to move relative to the flapper and thereby cause the flapper to be unseated from the flapper seat, a secondary valve disposed within the flow tube, the secondary valve including a secondary housing, and an openable and closable flow port through the secondary housing, and an annular pressure-drop ring disposed between the secondary housing and the flow tube.

摘要： A downhole component has a body including a first end portion, a second end portion and an intermediate portion extending therebetween. The intermediate portion includes an outer surface and an inner surface. The inner surface defines a flow path. An axial passage extends radially outwardly of the flow path between the outer surface and the inner surface. A piston is arranged in the axial passage. The piston includes a first end, a second end, an intermediate section extending therebetween and a frangible element arranged adjacent at least one of the first end, the second end, and along the intermediate portion.

摘要： A tubing pressure insensitive failsafe wireline retrievable safety valve, borehole system having the valve and method of operation of the valve. The valve includes a tool housing, a flow tube disposed within the tool housing, an actuation piston disposed in the tool housing and operably connected to the flow tube, the actuation piston having an actuation side and a pressure side, and a fluid pathway between a potential leak site for the valve and the pressure side of the piston. A temporary sealing member is in the fluid pathway between the potential leak site and the pressure side of the piston. The method includes disposing the valve at a selected location and removing at least a portion of the temporary sealing member from the fluid pathway after landing the wireline retrievable safety valve at the selected location.

摘要： A downhole tool including a valve portion having a valve housing including an inner chamber and an actuation tubular. The actuation tubular includes an outer surface, an inner surface defining a flow path, an upper end, and a lower end. A first spring extends about the outer surface of the actuation tubular between the upper end and the lower end. An actuator portion is detachably connected to the actuation tubular. The actuator portion includes an actuator housing, an actuator member arranged in the actuator housing, and a second spring operatively connected to the actuator member. The actuator member includes a first end portion operatively connected to the first spring and a second end portion. The actuator portion is selected and connected to the downhole tool to establish a selected actuation force through the second spring to compress the first spring causing the actuation tubular to shift within the inner chamber.

摘要： A downhole component includes a unitary body having a first end portion, a second end portion and an intermediate portion extending therebetween. The intermediate portion defines an outer surface and an inner surface forming a flow path. An annular chamber has a first end section spaced from a second end section by a gap. The annular chamber is formed in the unitary body spaced from the first end portion, the second end portion, the outer surface, and the inner surface.
