| 发明名称 | Rapid swelling and un-swelling materials in well tools | ||
| 摘要 | Rapid swelling and un-swelling materials provide for rapid actuation of well tools. A well tool can include a swellable material, with the swellable material comprising a swellable glass material. A method of actuating a well tool in a subterranean well can include contacting a swellable material of the well tool with an activating fluid in the well, thereby causing the swellable material to swell. The well tool rapidly actuates in response to contacting the swellable material with the activating fluid. | ||
