摘要:
A crosslinked product of a polyarylene is disclosed, having high-temperature elastomeric properties and excellent chemical resistance. The crosslinked materials are useful in oil and gas downhole applications in the form of either solids or foams. Methods for the manufacture of the crosslinked product and articles comprising the product are also disclosed.
摘要:
A method of deploying a borehole filtration device is provided utilizing the steps of: deploying a filtration device comprising a polymer foam having a first cell structure, a portion of the molecular structure of which polymer foam is degradable by exposure to a post-treatment fluid, into a borehole; and exposing the polymer foam to the post-treatment fluid, thereby modifying the cell structure of the polymer foam to a second cell structure.

摘要:
Thermally crosslinked polysulfone may be made from linear polysulfone, such as polyethersulfone, in powder form blended with a powdered inorganic peroxide such as magnesium peroxide or another oxygen source, to form a mixture followed by compression inside a mold. The mixture is cured at a an elevated temperature, for instance above 325° C., for an effective period of time to form a dense object. The object is then boiled in water, optionally under pressure, to remove the salt to give a structure that is open and porous which may be used as a filtration device on a downhole tool for hydrocarbon recovery. If a powdered salt is not used, a thermally crosslinked, solid, void-free polysulfone is made which may be strong and rigid at ambient, surface temperatures, but is an elastomer at elevated downhole temperatures, and is thus suitable for use as a packer or an O-ring.
