    • A sand control screen assembly (100) for use in a subterranean well. The sand control screen assembly (100) includes a base pipe (102) having an outer surface and at least one opening (104). A screen jacket (106) is disposed around the base pipe (102). The screen jacket (106) has a filter medium (112) and an outer shroud (114). The outer shroud (114) has first and second ends (124, 126) with inner and outer surfaces. Connector rings (120, 122) form mechanical interfaces between the base pipe (102) and the first and second ends (124, 126), respectively, of the outer shroud (114). Each of the connector rings (120, 122) is operable to mechanically induce permanent deformation in the outer surface of the base pipe (102) and at least one of the inner surface and the outer surface of the outer shroud (114), thereby connecting the screen jacket (106) to the base pipe (102).
    • 一种用于地下井的防砂筛网组件(100)。 防砂筛管组件(100)包括具有外表面和至少一个开口(104)的基管(102)。 屏蔽套(106)围绕基管(102)设置。 筛套(106)具有过滤介质(112)和外护罩(114)。 外护罩(114)具有内表面和外表面的第一和第二端(124,126)。 连接环(120,122)分别形成在底管(102)与外护罩(114)的第一和第二端(124,126)之间的机械接口。 每个连接环(120,122)可操作以在基管(102)的外表面和外护罩(114)的内表面和外表面中的至少一个上机械地引起永久变形,由此连接 所述筛套(106)到所述基管(102)。
