摘要： A completion tubular is placed in position adjacent the zone or zones to be fractured and produced. It features preferably sliding sleeve valves that can assume at least two configurations: wide open and open with a screen material juxtaposed in the flow passage. In a preferred embodiment the valve assembly has three positions, adding a folly closed position to the other two mentioned. After run in, the valves can be put in the wide open position in any order desired to fracture. After fracturing, the valves can be closed or selectively be put in filtration position for production from the fractured zones in any desired order. Various ways are described to actuate the valves. The tubular can have telescoping pistons through which the fracturing can take place if the application calls for a cemented tubular. Alternatively, the tubular can be in open hole and simply have openings for passage of fracture fluid and external isolators to allow fracturing in any desired order.

摘要： A downhole abrading tool having a body with a first end for connection to a drill string, a cutting end, a drilling fluid passageway, a restrictor disposed within drilling fluid passageway, and an indicator chamber is disclosed. Upon exposure of the indicator chamber to a well environment due to excessive wear on the cutting end, the restrictor is actuated. Actuation of the restrictor restricts the flow of drilling fluid from the drilling fluid passageway into the well environment. The restriction of flow of drilling fluid from the drilling fluid passageway causes a pressure increase in the drilling fluid flowing through the well that can detected by an operator of the downhole abrading tool. The pressure increase provides an indication to the operator of excessive wear on the cutting end of the downhole abrading tool so that the downhole abrading tool can be removed from the well and replaced.
摘要翻译：公开了一种井下研磨工具，其具有主体，其具有用于连接到钻柱的第一端，切割端，钻井流体通道，设置在钻井流体通道内的限位器和指示器室。在由于切割端上的过度磨损而使指示器室暴露于井环境中时，限制器被致动。限流器的驱动限制了钻井液从钻井液通道进入油井环境的流动。来自钻井液通道的钻井液流动的限制导致流经井的钻井液中的压力增加，钻井液可由井下研磨工具的操作者检测到。压力增加为操作者提供了在井下研磨工具的切割端上过度磨损的指示，使得井下研磨工具可以从井中移除并被更换。

摘要： A subterranean screen system features openings in a base pipe and sleeve sections of a porous material that preferably swells in the borehole to span an annular space around the base pipe. Retainers are mounted to the base pipe in a desired location and mechanically fixated using an internal grip system actuated through the wall of the retainer. A wedging action of slip segments is initiated by an angularly advancing assembly through the wall of the retainer. The retainer can have end rings extending past one or both ends over which the screen sleeve extends. Flat or ridges on the exterior of the retainer or end rings make assembly easier with hand tools to allow for rapid field assembly, if needed. Filtration occurs through the sleeves that abut the borehole wall and into the base pipe openings and to the surface.
