Gravel pack apparatus and method |
摘要 |
A wash down placement of a screen into sand within a well borehole is improved by vibration of a wash pipe as the wash pipe is removed from the screen. A compacted sand gravel pack around the screen is achieved. The vibrations are created by constraining a bluff object having a plurality of positions between which flow of fluid forces the bluff object.
