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.

摘要： A well tool includes a generally tubular mandrel with a flow passage extending longitudinally through the mandrel, and a flow controller which initially prevents a fluid from contacting a swellable material, but which permits the fluid to contact the material in response to manipulation of pressure in the flow passage. Another well tool includes a swellable material, a generally tubular mandrel, and a conduit wrapped circumferentially about the mandrel, the conduit containing a fluid which, upon contact with the swellable material, causes the material to swell. A method of actuating a well tool in a well includes manipulating pressure in a flow passage extending through a tubular string, thereby opening at least one flow control device of the well tool which selectively permits fluid communication between a reservoir of the well tool and a swellable material of the well tool, whereby a fluid in the reservoir contacts the swellable material.

摘要： A swellable packer can include a material which swells when contacted with a swelling fluid, and a barrier comprising a highly crystalline polymer which is substantially impermeable to the swelling fluid. A method of controlling swelling of a material can include positioning the material and a barrier in a well, the barrier preventing contact between the material and a swelling fluid, the barrier comprising a polymer, and increasing a permeability of the barrier to the swelling fluid in response to the barrier polymer being heated to its crystallization temperature. A well system can include a material which swells in response to contact with a hydrocarbon gas, and a barrier which comprises a crystalline polymer, the polymer being substantially impermeable to the hydrocarbon gas, whereby the polymer initially prevents swelling of the material, but the polymer becomes increasingly permeable to the hydrocarbon gas when heated to its crystallization temperature.

摘要： A method of verifying swelling of a swellable material in a well can include connecting a transmitter to a sensor which senses a parameter indicative of degree of swelling of the swellable material, and conveying a receiver into an interior of a tubular string. The transmitter transmits to the receiver an indication of the degree of swelling of the swellable material. A packer swelling verification system can include a swellable material which swells in a well, and a well tool which is conveyed to the packer in the well. The well tool receives an indication of a degree of swelling of the swellable material. A method of verifying whether a swellable material has swollen in a well can include positioning a conductor proximate the swellable material, whereby the conductor parts in response to swelling of the swellable material, and detecting whether the conductor has parted.

摘要： A well tool can include a swellable material, and a degradable material which supports the swellable material, but which degrades in response to contact with a selected fluid in a well. A packer for use in a subterranean well can include a swellable material, and a degradable material which supports the swellable material. A method of unsetting a packer in a subterranean well can include the steps of, after the packer has been set in the well, exposing a degradable material of the packer to a selected fluid, thereby degrading the degradable material, and a seal element of the packer being unsupported by the degradable material in response to the exposing step.
