    摘要： A hydraulically operated fluid metering apparatus provides discharge of a known volume of fluid to an actuator of a well tool. In one described embodiment, the fluid metering apparatus is connected to a hydraulic input of a well tool actuator. Discharge of the known volume of fluid to the actuator input causes a piston of the actuator to displace a known distance, thereby producing a known increment of actuation of the well tool. The discharge of the known volume of fluid may be repeated to produce a desired total degree of actuation of the well tool.

    摘要： A downhole apparatus adapted to be run on a workstring in a well bore. The apparatus has a body including ports and a valve which is rotatable to open and close the ports to selectively allow fluid flow through the body between regions of a well bore above and below the apparatus. The valve is rotated via a gearbox and motor in the apparatus. A sealing arrangement between the valve and body is also described. A method of running the apparatus in a well bore and monitoring pressure above the apparatus in order to control opening and closing of the valve under predetermined conditions is presented.

    摘要： A retrievable large bore packer for providing an annular seal and an anchor system in a well bore. Ports are provided behind the slips to prevent debris build-up and allow the slips to release. These ports, in a thin walled tubing, allow the collapse of the tubing behind the slips to aid removal of the packer if the sealing element does not release. The slip arrangement is mounted entirely above the sealing element to remove the requirement to seal between the slips and the inner bore of the packer. In this way the packer can have a large bore. Further flow paths are provided through the packer above the seal to prevent debris build-up above the sealing element.

    摘要翻译： 一种用于在井眼中提供环形密封件和锚固系统的可回收的大孔封隔器。 端口设置在滑块后面，以防止碎屑积聚并允许滑块释放。 如果密封元件不释放，这些端口处于薄壁管道中，允许在滑动件后面的管道塌陷以帮助去除封隔器。 滑动装置完全安装在密封元件的上方，以消除在滑动件和封隔器的内孔之间的密封的要求。 以这种方式，封隔器可以具有大的孔。 通过密封件上方的封隔器提供进一步的流动路径，以防止在密封元件上方产生杂质。

    摘要： A lock member (10) is disclosed for securing to a lock structure (14) in a conduit. The lock member (10) comprises a housing (24), a shoulder (16) on the lock structure (10), a locking device (26) movably mounted on the housing (24) for movement between a first retracted position and a second extended position in which the locking device (26) enters a corresponding locking recess (30) in the lock structure (14). The shoulder (16) of the lock member (10) is movably mounted on the housing (24) between a first position in which, in use, the shoulder (16) bears upon the shoulder (18) of the locking structure (14) and the locking device (26) when in the extended position is disengaged from the surfaces of the locking recess (30) of the lock structure (14). When the shoulder (16) of the lock member (10) is in the second axial position, the locking device (26) bears upon a surface of the locking recess (30) so as to bear at least a portion of any load applied to an end of the lock member (10). The lock member (10) also includes a selective locking device (32) for selectively locking the shoulder (16) in the first position. The lock member is particularly advantageous when used in an oil or gas well and especially tubing in oil or gas wells. In this case, the lock member is in the form of a lock mandrel and the lock structure is in the form of a landing nipple.

    摘要： A well tubing valve is described, having a substantially tubular body connected in a tubular string and a rotational valve member having at least one aperture. The valve member, which may be a sleeve having a part spherical surface, is rotationally moveable relative to the body to align and misalign the aperture in the valve member with a port in the body. The valve member is actuable to rotate relative to the body in a single direction, and moves from the open position to a closed position and back by rotation in the same sense. In an alternative embodiment, two such valves members are provided and each valve member is actuable from a common control line to at least three operating positions, to. incrementally adjust flow through the ports. Methods of operation are also described.
