摘要： Pressure control in an isolated lower wellbore annulus, defined by a conduit sealably positioned within an isolated lower wellbore segment, is achieved while gravel packing by sensing the pressure within the isolated lower annulus while gravel packing and admitting fluid from the isolated lower annulus into the conduit at one or more discrete locations along the conduit when the sensed pressure corresponds to one or more threshold pressure conditions. The annulus pressure is sensed while gravel packing using a pressure-sensitive device disposed in the annulus, e.g., positioned by the conduit at a high-pressure location. The pressure-sensitive device actuates one or more valves carried along the conduit to admit fluid from the annulus into the conduit at one or more of the discrete locations, and thereby control the pressure in the isolated lower annulus.
摘要翻译： 通过密封地定位在隔离的下井眼段内的导管限定的隔离的下井眼环中的压力控制是通过感测隔离的下环形空间内的压力而进行砾石填充的，同时砾石填充并将流体从隔离的下环空导入管道 当所感测的压力对应于一个或多个阈值压力条件时，沿着导管的一个或多个离散位置。 在使用设置在环形空间中的压敏装置的砾石填充时感测到环形空间压力，例如由导管在高压位置定位。 压敏装置致动一个或多个沿着管道携带的阀，以将流体从环形空间进入导管中的一个或多个离散位置，从而控制隔离的下环空间中的压力。

摘要： A method of providing zonal isolation in a wellbore completion includes the steps of identifying an anticipated zone for isolation in a wellbore before completing the wellbore; selecting, before completing the wellbore, a completion assembly and a cooperative deployable isolation assembly to isolate the anticipated zone; completing the wellbore with the selected completion assembly; and connecting the selected deployable isolation assembly in the selected completion assembly to isolate the anticipated zone.
