    • A well completion assembly including apparatus for gravel packing and cementing in a single trip. An outer assembly comprises: a liner and screen; a valved gravel packing port; upper and lower valved cementing ports; and seal bores positioned below and above the gravel packing port and above and below the lower cementing port. An inner assembly includes: a crossover having an outer seal body and shifters to allow opening and closing of valves in the gravel packing and cementing ports. In one position, the crossover seal body mates with seal bores below and above the gravel packing port to allow flow of gravel packing slurry through the gravel packing port. In a second position, the crossover seal body mates with seal bores below and above the lower cementing port to allow flow of cement through the lower cementing port.
    • 一个完井组件,包括一次砾石包装和固井装置。 外部组件包括:衬里和屏幕; 有砾石填料口; 上,下阀门固井口; 以及位于砾石填充口下方和上方以及下部固井口上方和下方的密封孔。 内部组件包括:具有外部密封体和换档器的交叉口,以允许打开和关闭砾石包装和固井口中的阀。 在一个位置,交叉密封体与砾石填充口下方和上方的密封孔配合,以允许砾石填充浆液流过砾石填料口。 在第二位置,交叉密封体与下部固井口下方和上方的密封孔配合,以允许水泥通过下部固井口。

    • An improved blast liner assembly for use in gravel packing or fracturing operations wherein solid materials, in slurry form, are flowed out of the flowbore of a working tool and into the annulus of a wellbore. The blast liner is a cylindrical member that provides a protective shield to the interior retaining section. An angular flow diverter is provided within the blast liner and has a plurality of angled flow diversion channels formed into the inner surface of the blast liner body. Flow of slurry through the blast liner will cause the blast liner to rotate within the retaining section due to the reaction forces imparted to the blast liner from diverting the slurry flow. In this manner, the impingement area presented by the blast liner is increased, and the life of the blast liner extended. The blast liner may also be caused to move axially within the retaining section to further increase the impingement area.
    • 用于砾石填充或压裂操作的改进的鼓风衬套组件,其中浆料形式的固体材料从工作工具的流道中流出并进入井眼的环形空间。 鼓风衬套是向内部保持部分提供防护罩的圆柱形构件。 鼓风衬套内设有角流分流器,并且具有形成在鼓风衬套主体内表面上的多个成角度的分流通道。 浆料通过鼓风衬套的流动将导致鼓风衬套在保持部分内旋转,这是由于赋予鼓风衬套的反作用力导致浆料流转向。 以这种方式,由鼓风衬垫呈现的冲击区域增加,鼓风筒的寿命延长。 鼓风衬套也可以在保持部分内轴向移动,以进一步增加冲击面积。

    • Disclosed is a workstring for use in a gravel packing system. The workstring includes a washpipe with at least one port and a selectively openable and closeable closure mechanism in operable communication with the at least one port. Further disclosed is a collet having a collet base and a plurality of collet fingers extending from the collet base. At least one of the collet fingers includes retaining feature, the retaining feature being configured to yield under bending at a selected valve. Yet further disclosed is a method for gravel packing. The method includes gravel packing a wellbore including opening one or more valves in a washpipe as pressure associated with the gravel packing climbs, the valves providing an escape path for a fluid component of the gravel pack to an inside dimension of the washpipe. The method further includes closing the one or more valves in the washpipe.
    • 公开了一种用于砾石包装系统的工作绳。 工作绳包括具有至少一个端口和可选择地可打开和可关闭的闭合机构的洗涤管,其与所述至少一个端口可操作地连通。 进一步公开了一种夹头,其具有从夹头基部延伸的夹头基部和多个夹头。 夹头中的至少一个包括保持特征,保持特征被配置为在所选择的阀处屈服于弯曲。 还公开了一种用于砾石包装的方法。 该方法包括砾石填充井筒,包括在冲洗管中打开一个或多个阀,作为与砾石填料爬升相关联的压力,所述阀为砾石填料的流体组分提供到冲洗管的内部尺寸的逃逸路径。 该方法还包括关闭洗涤管中的一个或多个阀。
