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： An electronic actuation system for a pressure equalising device in a downhole apparatus such as a wellbore plug is described. The system includes a pressure sensor for measuring pressure in the wellbore, and means for setting a reference pressure value using a measurement from the pressure sensor. In a method of use, an applied pressure value is determined using a measurement from the pressure sensor and the reference pressure value, and the device is actuated, or opened, when the applied pressure meets a pre-determined condition, such as falling within a pressure window for certain time period. The invention allows natural changes in wellbore pressure to be accounted for when detecting a pressure actuation event.

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.

摘要： A fluid operated apparatus in the form of a flow cap, is mounted on an end of a downhole tool or sub, which itself has a screw thread fitting to a further tool, sub or tubular. The cap provides a number of fluid flow channels arranged in a spiral pattern upon the outer surface. The handedness of the channels matches the handedness of the screw thread fitting so that fluid flow from ports in the tool or sub, acts to tighten the screw thread fitting. A water injection valve including a flow cap is described.

摘要： Apparatus and method for a providing a completion assembly for running at an end of a completion string which provides a remotely operable tubing mounted valve used to control the flow of fluids through the tubing in hostile well conditions. The tubing mounted completion assembly has a tubular body for connection in the string below a production packer with a through bore from a first inlet and a first outlet coaxially aligned with the string; a downhole electronic actuating mechanism, a downhole hydraulic pump and a hydraulically operated ball valve member. The actuating mechanism operates the hydraulic pump to provide a hydraulic control line to control movement the valve member from a first position, where the member is open and a through bore is created between the inlet and outlet of the assembly, to a second position, where the valve seals the throughbore and, finally, back to the first position.
