    摘要: A flush valve for a multiple line hydraulic system includes a bifurcated manifold, the bifurcation being provided by a piston actuatable hydraulically, mechanically, electrically magnetically or by fiber optic means. The piston or gate is provided with a port extending diametrically therethrough and oriented to become coaxial with an inlet and outlet of the manifold upon actuation of the piston. With the port aligned the hydraulic fluid in the system can be displaced by fresh fluid. The piston is then deactivated which results in the port becoming misaligned with the inlet and outlet of the manifold. In this condition the hydraulic system is again sealed and functions normally.

    摘要: Internal and external metal-to-metal radially interfering seals are provided for an annular chamber. Typically, an annular chamber is used in tubular goods to be part of the hydraulic control circuitry, such as for operating subsurface equipment such as a subsurface safety valve. Resilient seals are eliminated and sealing reliability is enhanced by a design which features metal-to-metal seals internally and externally, preferably assembled by an external two-step thread. The radial interference seal, which is internally disposed, is constructed so as to be incapable of experiencing tensile loads. This reinforces joint integrity by minimizing stresses on thin components.

    摘要: A downhole fiber optic protection system is disclosed which includes at least one protector sub mounted in a downhole string, the protector sub having at least one recess formed in an outside diameter of the protector sub and optionally including component protectors mounted to the outside diameter of the protector sub whereby the one or more recesses in the outside of the protector sub provide protection to fiber optic components and protected areas are created underneath component protectors further more delicate of the fiber optic connectors. The device is designed to prevent the harsh downhole environment from adversely affecting optical fibers themselves or optical components in the optical fiber system.

    摘要: The invention relates to valves usable downhole and controlled from the surface hydraulically via control lines or by other techniques. The valve has a minimum flow passage which is preferably oriented along its longitudinal axis and a lateral flow passage which opens upon movement of a valve member via applied control pressure from the surface. Alternatively, the valve comprises a tapered needle movable in a throat. When the valve member shifts, additional flow area is exposed to control the backpressure of a fluid by way of hydraulic pressure control from the surface via the control line. The hydraulic control can be with a single control line acting on a piston attached to the valve member with a return spring opposing such movement, or alternatively, can be carried out with a pair of control lines to actuate reverse movements of the valve member. A pressurized gas chamber can be used to act as the closing force opposing applied pressure from the control line for a return of the valve to its minimum flow or maximum throttle position. Alternatively, an acoustic, electric or other type of surface-directed signal can change the valve position.
