摘要： A transient overbalance condition is created in a wellbore interval such that a pressure of the wellbore interval is greater than a reservoir pressure in surrounding formation. Creating the transient overbalance condition causes a near-wellbore region of the formation to increase in pressure. The pressure in the wellbore interval is reduced at a rate that produces a relative underbalance condition in which the pressure in the wellbore interval is less than the pressure of the near-wellbore region of the formation, but the pressure in the wellbore interval is greater than the reservoir pressure.

摘要： A completion string for use in a wellbore includes a main conduit, such as a production tubing, and one or more alternate path conduits, such as shunt tubes, that extend generally in parallel with the main conduit. A flow control device is positioned in each alternate path conduit to control flow through the alternate path conduit. The one or more alternate path conduits may be adapted to carry gravel slurry to perform gravel packing operations. The one or more flow control devices in the one or more alternate path conduits may be actuated to the open position to allow communication of the gravel slurry to multiple zones in the wellbore. Once the gravel packing operation is completed, the one or more flow control devices may be actuated to the closed position to block fluid flow communication between multiple zones through the alternate path conduits during operation of the well. Other types of fluids may be communicated through the one or more alternate path conduits, such as fracturing fluids.

摘要翻译： 在井眼中使用的完井柱包括主管道，例如生产管道，以及一个或多个替代路径管道，例如分流管，其大致平行于主管道延伸。 流量控制装置位于每个备用路径管道中，以控制通过备用路径管道的流量。 一个或多个备用路径管道可以适于承载砾石浆料以执行砾石包装操作。 一个或多个替代路径管道中的一个或多个流量控制装置可以被致动到打开位置，以允许砾石浆料与井筒中的多个区域连通。 一旦完成了砾石包装操作，则一个或多个流量控制装置可以被致动到关闭位置，以在井的操作期间通过交替路径导管阻止多个区域之间的流体流动连通。 其他类型的流体可以通过一个或多个替代路径导管（例如压裂流体）传递。

摘要： A well screen having an internal, blank alternate flowpath for delivering fracturing fluid/gravel slurry to different levels within a well annulus. The well screen includes an outer pipe which is positioned over a base pipe thereby forming an annulus therebetween. The circumference of each pipe has a perforated sector and a blank sector, both of which extend along their respective lengths. When assembled, the respective perforated sectors are aligned to form a perforated, production sector and the respective blank sectors are aligned to form the blank, alternate flowpath. The base pipe is wrapped with wire to prevent solids from flowing through the openings therein. Slurry is pumped into the annulus where it flows circumferently from the blank, alternate flowpath to exit into the well annulus through the openings in the perforated sector of the annulus.

摘要翻译： 具有内部空白交替流路的井筛，用于将压裂液/砾石浆料输送到井环内的不同水平。 井筛包括外管，其位于基管上方，从而在它们之间形成环形空间。 每个管的圆周具有穿孔扇区和空白扇区，两者都沿其相应的长度延伸。 当组装时，相应的穿孔扇区对准以形成穿孔的生产扇区，并且相应的空白扇区对齐以形成空白，交替的流动路径。 基管用线包裹以防止固体流过其中的开口。 浆料被泵送到环形空间中，其中空气从环形空间周围流动，交替的流动路径通过环带的穿孔扇区中的开口离开井环。
