摘要： A damage-resistant filter for use in subterranean wells has at least one layer of a filter medium, such as a sintered supported porous membrane, coaxially disposed about a perforated support member. The filter may also include a drainage layer disposed between the inner support member and the filter medium, and a protective covering, such as a perforated cage, surrounding the filter medium. The filter is particularly suitable for removal of sand and other particulates from fluids produced in a well.

摘要： A method for making seamless, porous metal articles comprising:(a) rotating a mold containing a stabilized suspension of a metal particulate at a rate and for a time such that the particulate is separated from the suspension and distributed on the interior wall of the mold, thereby forming a structure conforming to the interior wall of the mold, the rate of rotation being sufficiently high that, preferably, at least about 65 Gs up to 100 Gs of centrifugal acceleration is achieved at the interior wall of the structure,(b) drying the formed structure to provide a structure having green or unsintered strength, and(c) sintering the dried structure to remove volatile material and fuse the individual particles of the particulate to each other to form the seamless, porous metal article.Metal articles in accordance with the invention have substantially uniform diameters, thicknesses and pore structurs, have Bubble Point ratios of greater than 1.5 up to 2.5, and find particular use as filters. 0044

摘要： A method of making a porous metal article is disclosed comprising:(a) applying a stabilized suspension of a dispersed metal particulate in a fluid medium to a porous metal support;(b) working the support to fill the openings with the stabilized suspension and remove entrained gas;(c) heating the filled support to dry the stabilized suspension and provide the filled support with green or unsintered strength;(d) preferably compressing the dried, filled support to provide better contact between adjacent particles and greater mechanical strength; and(e) sintering the compressed, dried, filled support to remove volatile material and to fuse the individual particles of the metal particulate to the metal support and to each other.The porous metal articles find particular use as filters. They comprise a porous metal support and metal particulate material with the individual particles sinter bonded to each other and to the support. Preferably, the porous articles are formed from austenitic stainless steel containing less than 0.03 parts by weight carbon, have F2 pore ratings at beta=100 of from about 0.1 to about 50 micrometers and are capable of being formed about a bending radius of five or less times the thickness of the article while maintaining their integrity.
