    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.

    摘要翻译： 本发明涉及可在井下使用的阀门，并通过控制管路或通过其他技术从液压控制。 阀具有最小的流动通道，其优选地沿着其纵向轴线定向，并且横向流动通道在通过施加的控制压力从表面移动时打开。 或者，阀包括可在喉部中移动的锥形针。 当阀构件移动时，额外的流动面积被暴露以通过经由控制线的表面的液压控制来控制流体的背压。 液压控制可以是单个控制线，其作用在附接到阀构件的活塞上，具有与该运动相对的复位弹簧，或者可以用一对控制管线来执行以致动阀构件的反向运动。 加压气体室可以用作与控制线相反的施加压力的关闭力，用于将阀返回到其最小流量或最大节流位置。 或者，声，电或其他类型的面向信号可以改变阀位置。

    摘要： A high load wireline lock features a plurality of dogs supported by a fishing neck. Radial loads, transmitted through the dogs when the lock is engaged, are in turn directed into the fishing neck in the manner so as to distribute the load into the wall of the fishing neck. The contact between the dogs and the fishing neck is along sloping surface which minimize the radial forces against the fishing neck and in turn applies forces in a near tangential direction through the wall of the fishing neck thus greatly increasing the load capacity of the wireline lock.

    摘要： A check valve for gas lift applications can be attached externally to a side pocket mandrel or can be a gas lift valve used in the mandrel. The valve has a seat with a non-elastomeric element and a metal element. A biasing element resiliently biases the non-elastomeric element to provide resiliency to the seal produced. A metal dart moves in the bore relative to the seat and allows or prevents flow through the valve body. When exposed to a first differential pressure, the dart engages the non-elastomeric element resiliently biased by the biasing element. When exposed to a greater differential pressure, the dart engages the metal element, which can be part of the valve in the bore. In one arrangement, the non-elastomeric element can be a thermoplatistic component with a metal spring energized seal as the biasing element. Alternatively, the non-elastomeric element can be the jacket of metal spring energized seal with a coil spring as the biasing element.

    摘要： A method and apparatus for preventing erosion of a cable for use in a wellbore is described herein. The cable has one or more optical fibers adapted to monitor and/or control a condition in the wellbore. The cable includes a layer of elastomeric material at least partially located on an outer surface of the cable. The elastomeric material is adapted to absorb energy due to the impact of particles in production fluid or wellbore fluid against the cable.
