摘要： A retrievable subsurface safety valve positioned in a well conduit is actuated to close by a predetermined flow rate through the safety valve. A valve member having a sealing surface is moveable by flow to sealingly engage an annular seat in the valve, closing the valve to flow. All forms of the invention safety valve have retrievable variable weight assemblies which releasably lock in the valve member for varying the flow rate at which each valve closes. In two invention forms, the weight assemblies when retrieved from the valve members leave the valve members open for passage of well tools through the valve members. In one invention form, the valve housing has a variable bias for biasing the valve member toward open position and this safety valve may be operated to expend the seat, housing and valve member with or without the variable weight assembly.

摘要： A hydraulically set retrievable well packer, with dual mandrels connectable into well tubing, for sealing the tubing to and anchoring the packer body in well casing utilizing a unique C-ring slip anchoring system. The mandrels are slidably connected for limited longitudinal movement in the packer body, which eliminates tubing spacing-out and temperature length change problems. There is a separate mandrel through the packer body for conducting flow from the casing annulus below the set packer. An internal lock system is provided to retain the packer in set position. If tubing parts above the set packer, the mandrels are supported and metal-to-metal sealed in the packer preventing tubing below the packer from falling. The packer may be retrieved by cutting one or both mandrels above the packing elements and picking up to release an internal connector which allows the slips and packing element to retract and the packer to be retrieved from the well. The anchoring, sealing and releasing means of this invention may be readily adapted for use on a single or multiple mandrel well packer.
摘要翻译：一种液压设置的可回收井封隔器，具有可连接到井管中的双心轴，用于使用独特的C形环滑动锚定系统将管道密封并将封隔器主体锚定在井套管中。心轴可滑动地连接在封隔器体内的有限纵向运动中，这消除了管道间隔和温度长度变化问题。通过封隔器主体有一个单独的心轴，用于从套管封隔器下面的套管环进行流动。提供内部锁定系统以将封隔器保持在设定位置。如果设置封隔器上方的管道部件被支撑，并且将金属对金属密封在封隔器中，防止封隔器下方的管路掉落。可以通过在包装元件上方切割一个或两个心轴并拾取以释放内部连接器来取回封隔器，该内部连接器允许滑移和包装元件缩回并且打包机从井中取回。本发明的锚定，密封和释放装置可以容易地适用于单个或多个心轴封隔器。

摘要： A well system and method for completing petroleum oil and gas wells having special application to extreme environmental settings such as platform, sub sea, and floating vessel operations, and frozen regions such as the Arctic. The system effectively defines a downhole wellhead including weight supporting apparatus in which the tubing hanger is supported and a pack-off with the casing for minimizing the effects of structural damage at the surface end of the well system. The system includes a tubing hanger releasably lockable in a casing at a downhole location and having sealing means for sealing the annulus within the casing around the hanger, a ball valve package lock releasably lockable in the tubing hanger, tubing strings connected with the ball valve package lock and extending upwardly therefrom, including tubing valves, a safety joint connected with the tubing strings above the valves, tubing strings connected with the safety joint extending upwardly to a tubing head at the wellhead, control fluid conduits connected from the tubing head through the safety joint to the ball valve package lock and tubing hanger for manipulation of the system during various phases of operation, and a composite handling string for running and pulling the well system including either of a slip joint or a hydraulic stop and orienting tool.

摘要： An apparatus is described for controlling flow of fluid in a tubular positioned in a wellbore extending through a subterranean formation. A flow control system is placed in fluid communication with a main tubular. The flow control system has a flow ratio control system and a pathway dependent resistance system. The flow ratio control system has a first and second passageway, the production fluid flowing into the passageways with the ratio of fluid flow through the passageways related to the characteristic of the fluid flow. The pathway dependent resistance system includes a vortex chamber with a first and second inlet and an outlet, the first inlet of the pathway dependent resistance system in fluid communication with the first passageway of the fluid ratio control system and the second inlet in fluid communication with the second passageway of the fluid ratio control system. The first inlet is positioned to direct fluid into the vortex chamber such that it flows primarily tangentially into the vortex chamber, and the second inlet is positioned to direct fluid such that it flows primarily radially into the vortex chamber. Undesired fluids, such as natural gas or water, in an oil well, are directed, based on their relative characteristic, into the vortex primarily tangentially, thereby restricting fluid flow when the undesired fluid is present as a component of the production fluid.

摘要： A downhole tool for use in a wellbore tubular string comprises a housing having a bore therethrough forming part of a fluid flowpath through the wellbore tubular string, a sliding member operable to slide with respect to the housing, a plurality of magnetic pins, and a corresponding plurality of springs. A sliding line is formed by interfacing surfaces of the sliding member and the housing, and the plurality of pins comprise a locked position and an unlocked position whereby in the locked position at least one pin spans the sliding line to prevent the sliding member from sliding with respect to the housing and in the unlocked position no pins span the sliding line. The plurality of springs biases the pins towards the locked position.

摘要： Apparatus and methods are provided for achieving a lateral wellbore connection in a subterranean well. In one described embodiment, a deflection device is rotatably attached to one orienting member and conveyed into a cementing shoe positioned in a parent wellbore of the well, wherein the orienting member is engaged with another, complementarily shaped, orienting member. The deflection device is then rotated to face toward the lateral wellbore-to-be-drilled and a force is applied to the deflection device, thereby fixing its rotational orientation relative to the orienting members. Cutting tools are deflected off of the deflection device to cut outward through the cementing shoe to form the lateral wellbore.

摘要： Disclosed is an improved method and apparatus for providing selective access to either a main well or a lateral well extending from the main well. A sleeve assembly installed in the junction of a main and lateral well includes a housing with a side window and a slidable internal sleeve for locating in either an "up" position or a "down" position. When the internal sleeve is "up", the side window is uncovered so that downhole tools select the main wellbore by gravity. When the internal sleeve is "down", it covers the side window and guides downhole tools into the lateral well. When first making a lateral well, the lateral wellbore may be lined through a window in the main wellbore casing and a window opened in the wall of the lateral wellbore liner, in vertical alignment with the main well flow conductor. A sleeve assembly installed in the lateral wellbore liner, proximate the liner window includes a housing with a window and a slidable internal sleeve for locating in either an "up" position or a "down" position. When the internal sleeve is "up", the lateral liner window is uncovered so that downhole tools select the main wellbore by gravity. When the internal sleeve is "down", it covers the lateral liner window and guides downhole tools into the lateral well.
