SYSTEM AND METHOD FOR GRAVEL PACKING A WELLBORE |
摘要 |
A downhole tool includes a housing having a screen. An inner tubular member is positioned radially-inward from the housing such that an annulus is formed therebetween, and a first opening is formed radially-through the inner tubular member. A valve is positioned within the annulus. A flow control device is positioned within the annulus. A degradable member is configured to at least partially degrade in response to contact with a fluid. The valve is configured to actuate from a first position to a second position in response to the degradable member at least partially degrading. This changes a proportion of the fluid that flows through the flow control device after entering through the screen. |
