    • A valve includes; a housing having an opening; a mandrel disposed in the housing, the mandrel having an opening; a rupture disk disposed in a passageway of the mandrel;a sliding sleeve disposed between the housing and the mandrel; and a ball seat disposed in the mandrel. A method for actuating a includes: flowing a fluid through the valve; dropping a ball; seating the ball in the ball seal and blocking fluid flow through the mandrel; flowing fluid through the passageway to the sliding sleeve; moving the sliding sleeve axially within the valve; and exiting fluid through the openings of the housing and mandrel A valve includes: a housing having an opening; a mandrel disposed In the housing, the mandrel having an opening and a passageway; a sliding sleeve disposed between the housing and the mandrel; and a bail seat disposed in the mandrel blocking fluid communication between the mandrel and the passageway.

    • An apparatus and method of creating a seal between two coaxial tubulars so as to create a hanger and a packer. A first tubular (200) is disposed coaxially within a portion of a second, larger tubular (400). A portion of the first tubular is expanded into frictional contact with the second tubular, thereby creating a liner and a hanger. In one embodiment, a pattern of grooves (210) and profile cuts (205) is formed in the surface of a portion of the first tubular body. The grooves and profile cuts in one aspect define a continuous pattern about the circumference of the tubular body which intersect to form a plurality of substantially identical shapes, such as diamonds. The grooves and profile cuts serve to improve the tensile strength of the tubular body. At the same time, the grooves and profile cuts allow for expansion of the tubular body by use of less radial force. The grooves and profile cuts further provide a gripping means, providing additional frictional support for hanging the expanded tubular onto the inner surface of a surrounding second tubular. Carbide inserts (220) are preferably interdisposed within the pattern of grooves, providing additional gripping means when the smaller diameter tubular body is expanded into the second tubular.
    • 一种在两个同轴管之间产生密封以便产生衣架和封隔器的装置和方法。 第一管(200)同轴地布置在第二较大管(400)的一部分内。 第一管的一部分膨胀成与第二管的摩擦接触,从而形成衬垫和衣架。 在一个实施例中,在第一管状体的一部分的表面中形成凹槽(210)和轮廓切口(205)的图案。 在一个方面中的凹槽和轮廓切割限定了围绕管状体的圆周的连续图案,其相交以形成多个基本相同的形状,例如菱形。 凹槽和轮廓切割用于提高管状体的拉伸强度。 同时,凹槽和轮廓切割允许通过使用较小的径向力来膨胀管状体。 凹槽和轮廓切割进一步提供夹持装置,提供用于将膨胀管悬挂在周围的第二管的内表面上的额外的摩擦支撑。 硬质合金刀片(220)优选地插入凹槽的图案中,当较小直径的管状体膨胀成第二管时,提供附加的夹紧装置。
