摘要： A modular screen system allows connection of screens using couplings that connect the annular space in each module between the screen material and the base pipe. A series of connected screens and couplings feed into a single valve to control the flow through many screens. The valve is preferably located in a coupling and the passages through the coupling or the screen can also accommodate instrumentation to detect, store or transmit well data or flows through the various screen modules.

摘要： A fracturing and gravel packing tool has features that prevent well swabbing when the tool is picked up with respect to a set isolation packer. An upper or jet valve allows switching between the squeeze and circulation positions without risk of closing the wash pipe valve. The wash pipe valve can only be closed with multiple movements in opposed direction that occur after a predetermined force is held for a finite time to allow movement that arms the wash pipe valve. The jet valve can prevent fluid loss to the formation when being set down whether the crossover tool is supported on the packer or on the smart collet.

摘要： A fracturing and gravel packing tool has features that prevent well swabbing when the tool is picked up with respect to a set isolation packer. An upper or multi-acting circulation valve allows switching between the squeeze and circulation positions without risk of closing the low bottom hole pressure ball valve. The low bottom hole pressure ball valve can only be closed with multiple movements in opposed direction that occur after a predetermined force is held for a finite time to allow movement that arms the low bottom hole pressure ball valve. The multi-acting circulation valve can prevent fluid loss to the formation when being set down with the crossover tool supported or on the reciprocating set down device and the multi-acting circulation valve is closed without risk of closing the wash pipe valve.

摘要： A device or system for controlling fluid flow in a well includes a flow control element and a water detector. The water detector may actuate the flow control element in response to a measurement of a property of the flowing fluid. The water detector may be a capacitive proximity sensor. The measured property may be a dielectric constant. The flow control element may permit a predetermined amount of fluid flow after being actuated to a closed position. Also, the water detector may measure a property of the fluid flowing after the flow control element is in the closed position. A method for controlling a flow of fluid into a wellbore tubular may include positioning a flow control element along the wellbore tubular; measuring a property of a flowing fluid using a water detector; and actuating the flow control element in response to the measurement.

摘要： A crossover tool that resists the erosive forces of high velocity slurry streams of gravel in downhole fracturing and gravel packing operations employs hardened inserts that protect the inside face of the housing as well as the openings through the crossover housing wall. The inserts have an extending portion that goes through housing openings preferably to the outer surface of the housing. The inserts also have inboard flanged surfaces that preferably abut or overlap to give preferably foil inner wall protection to the housing from the flow of abrasive slurry. The inserts can be secured to each other or to the interior of the housing to hold them firmly in place.

摘要： Wear is reduced in abrasive slurry service at an outlet into an annular space defined by the wellbore and around the tool. In a gravel packing application with a crossover, the slurry exits a central passage and goes into an internal annulus in the tool. Turning vanes that make at least one full turn and that have a height at least partially the height of the annular space are there to impart a swirl movement to at least a portion of the slurry stream. The swirling motion has beneficial effects of reducing turbulence which allows a velocity reduction for a comparable output volume. As a result of the lower turbulence leading to the final exit from the tool into the surrounding annulus, the exit ports experience reduced erosion and longer service life.
摘要翻译：在出口处的磨料浆料服务中的磨损减少到由井筒和工具周围限定的环形空间中。在具有交叉的砾石包装应用中，浆料离开中心通道并进入工具中的内部环形空间。使至少一整圈的转动叶片至少部分地具有至少部分高度的环形空间，这样就可以向浆液流的至少一部分施加漩涡运动。旋转运动具有减少湍流的有益效果，其允许相当的输出体积的速度降低。由于较低的湍流导致从工具最终退出到周围的环空中，出口经历减少的侵蚀和更长的使用寿命。
