摘要： An apparatus (110) and method for treating an interval of a wellbore comprises an outer tubular (112) disposed within the wellbore. A sand control screen (118) is disposed within the outer tubular (112). A treatment fluid passageway (144) is formed between the sand control screen (118) and outer tubular (112). In addition, a production pathway (130) is formed between the sand control screen (118) and outer tubular (112). When the apparatus (110) is in an operable position, the region between the outer tubular (112) and the wellbore serves as a primary path for delivery of a treatment fluid, the production pathway (130) serves as a secondary path for delivery of the treatment fluid if the primary path becomes blocked and the treatment fluid passageway (144) serves as a tertiary path for delivery of the treatment fluid if the primary and secondary paths become blocked.
摘要翻译：用于处理井眼的间隔的装置（110）和方法包括设置在井眼内的外管（112）。防砂筛（118）设置在外管（112）内。在防砂筛（118）和外管（112）之间形成处理流体通道（144）。此外，在防砂筛（118）和外管（112）之间形成生产路径（130）。当设备（110）处于可操作位置时，外管（112）和井眼之间的区域用作用于输送处理流体的主路径，生产路径（130）用作辅助路径，用于递送如果主路径被阻塞，则处理流体，并且如果主路径和次路径被阻塞，则处理流体通路（144）用作用于递送处理流体的第三路径。

摘要： An apparatus and method for gravel packing an interval of a wellbore comprises an outer tubular (112), which forms a first annulus with the wellbore, and an sand control screen (118) disposed within the outer tubular (112) forming a second annulus therebetween. Within the second annulus is an axially extending production pathway (146) and an axially extending slurry passageway (144), which is defined between a sheet member (140) positioned on the sand control screen (118) and a channel (132). The outer tubular (112) has outlets (116) that are substantially aligned with outlets (142) of the channel (132). When a fluid slurry containing gravel is injected through the slurry passageway (144), the fluid slurry exits through the outlets (116, 142) leaving gravel in the first annulus, thereby gravel packing the interval.
摘要翻译：用于砾石填充井眼间隔的装置和方法包括：外管（112），其与井眼形成第一环带;以及设置在外管（112）内的防砂筛（118），其在其间形成第二环。在第二环形空间内是轴向延伸的生产路径（146）和轴向延伸的浆料通道（144），其限定在位于防砂筛管（118）上的片材构件（140）和通道（132）之间。外管（112）具有与通道（132）的出口（142）基本对准的出口（116）。当通过浆料通道（144）注入含有砾石的流体浆料时，流体浆料通过出口（116,142）离开在第一环形空间中留下砾石，从而将间隔包裹起来。
