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： Casing expansion and formation compression for permeability plane orientation. A method of forming at least one increased permeability plane in a subterranean formation includes the steps of: installing a casing section in a wellbore intersecting the formation; expanding the casing section in the wellbore; and then injecting a fluid into the formation, the injecting step being performed after the expanding step is completed. Another method includes the steps of: applying an increased compressive stress to the formation, the compressive stress being radially directed relative to a wellbore intersecting the formation; and then piercing the formation radially outward from the wellbore, thereby initiating the increased permeability plane. Yet another method includes the steps of: applying a reduced stress to the formation, the reduced stress being directed orthogonal to a wellbore intersecting the formation; and then piercing the formation with at least one penetration extending radially outward from the wellbore, thereby relieving the reduced stress at the penetration.

摘要： The present disclosure addressed apparatus and methods for forming an annular isolator in a borehole after installation of production tubing. Annular seal means are carried in or on production tubing as it is run into a borehole. In conjunction with expansion of the tubing, the seal is deployed to form an annular isolator. An inflatable element carried on the tubing may be inflated with a fluid carried in the tubing and forced into the inflatable element during expansion of the tubing. Reactive chemicals may be carried in the tubing and injected into the annulus to react with each other and ambient fluids to increase in volume and harden into an annular seal. An elastomeric sleeve, ring or band carried on the tubing may be expanded into contact with a borehole wall and may have its radial dimension increased in conjunction with tubing expansion to form an annular isolator.

摘要： Apparatus and corresponding methods are disclosed for controlling operation of well tools within a subterranean well. In a described embodiment, a remotely controllable actuator includes a pressurized fluid source and a chamber containing gas at a relatively low pressure. The actuator is operated by alternately connecting each of two chambers of the actuator to one of the low pressure chamber and the pressurized fluid source. In another described embodiment, a fluid containing chamber is connected to a low pressure chamber of an actuator to thereby bias one member to displace relative to another member.

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.

摘要： In a retrievable packer adapted for service under high temperature and high pressure operating conditions, improved retention of the packer in the wellbore is achieved by use of an inventive slip and wedge system, wherein the cones on the wedges are spaced a progressively slightly greater distance apart from their corresponding slip cones, from the centermost slip cone to the outermost slip cone. This forces the center of the slip to be loaded first. As greater forces are exerted on the wedges from end to end, the wedge will deform slightly and the next cone of the wedge will make contact with its matching portion of slip. Thereby, as the wedges are loaded higher and higher, more wedge cones come into bearing contact with the slip. Further, a barrel slip is used, to provide a uniform circumferential distribution of forces. This design effectively allows initial setting of the packer with very little slip tooth contact area. This permits the slip to quickly get a good grip into the casing wall. Subsequent higher loading brings more and more slip teeth to bear and prevents overstressing the casing.
摘要翻译：在适于在高温和高压操作条件下使用的可回收封隔器中，通过使用本发明的滑动和楔形系统来实现封隔器在井眼中的改进的保持性，其中楔形件上的锥形间隔开一个逐渐稍微更大的距离从其相应的滑动锥体，从最中心的滑动锥体到最外面的滑动锥体。这迫使滑块的中心首先被加载。随着越来越大的力从楔形到端部施加在楔形件上，楔形件将略微变形，并且楔形件的下一个锥体将与其匹配的滑动部分接触。因此，随着楔子的载荷越来越高，越多的楔形锥体与滑块接触。此外，使用桶形滑动，以提供均匀的力的周向分布。该设计有效地允许封隔器的初始设定具有很小的滑齿接触面积。这样就可以使滑动件快速地获得良好的握持到套管壁。随后的较高负载使得越来越多的滑动齿承受并防止套管的过度应力。
