摘要： A method for completing a well in a single trip is described, which includes inserting a completion tool assembly into the wellbore. The completion tool assembly includes a gravel packing assembly having a central channel substantially therethrough and a service tool assembly slidably positioned within the central channel. The service tool includes a pressure pulsating rotating jetting tool, connectable to a washpipe via a differential valve. By selectively dropping a plurality of plugging devices into the completion tool, multiple operations may be selectively performed in the wellbore in a single trip. In this way, the gravel packing and stimulating operations may be performed by a single completion tool assembly in a single trip into the wellbore, thus reducing the cost and time for performing the gravel packing and stimulating operations.
摘要翻译： 描述了在单次行程中完成井的方法，其包括将完井工具组件插入井眼。 完井工具组件包括一个具有基本穿过的中心通道的砾石充填组件和可滑动地定位在中心通道内的维修工具组件。 维修工具包括压力脉动旋转喷射工具，可通过差动阀连接到洗涤水管。 通过选择性地将多个插入装置放入完井工具中，可以在单次行程中在井眼中选择性地执行多个操作。 以这种方式，砾石填充和刺激操作可以通过单次完井工具组件在单次进入井眼中进行，从而降低了执行砾石填充和刺激操作的成本和时间。

摘要： A method for completing a well in a single trip, including: inserting a completion tool assembly into the well, the completion tool assembly having a gravel packing assembly and a service tool assembly slidably positioned substantially within an interior cavity in the gravel packing assembly; removably coupling the service tool assembly and the gravel packing assembly; plugging at a first location, whereby fluid is blocked from flowing through the interior channel; diverting fluid blocked by the plugging at the first location through a first fluid flow path to an exterior of the completion tool assembly; circulating a gravel pack slurry through the completion tool assembly; plugging at a second location, whereby fluid is blocked from flowing through the interior channel; diverting fluid blocked by the plugging at the second location through a second flow path that reenters the interior channel at a location distal of the first and second plugging locations; and circulating a filter cake stimulating fluid through the well completion assembly.

摘要： A method and apparatus for controlling fluid flow in a well bore is provided. A base pipe having an outer surface and an inner bore is provided. A first screen jacket is placed therearound. A second screen jacket is positioned adjacent the first screen jacket around the base pipe. An annular space is defined between the outer surface of the base pipe and each screen jacket. A sleeve is disposed between the adjacent screen jackets and an isolated fluid flow path is created between the annular space defined by the first screen jacket and the annular space defined by the second screen jacket.
