Patent number: 6991267Abstract: An elongated drive string assembly includes a plurality of hollow sucker rods and connecting elements between a drive head located at the surface of an oil well and a rotary pump located deep down in an oil well, with a series of holes at each end to substantially increase the flow of extracted fluid. Each hollow sucker rod has a first end with a torque shoulder, which engages a torque shoulder formed on a connecting element. The threads are frusto-conical, non-symmetrical threads with a differential diametral taper. The torque shoulders have a maximized mean diameter and cross-sectional area to resist storing reactive torque in the drive string.Type: GrantFiled: September 24, 2003Date of Patent: January 31, 2006Assignee: Siderca S.A.I.C.Inventors: Hugo A.

Publication number: 20040164209Abstract: An assembly for storing elongated members, the assembly comprising an elongated support element and a pair of segments. The segments are disposed on opposite sides of the elongated support element from each other, and each of the segments defines a cradle for supporting an elongated member. The pair of segments is joined together at a seam formed by locally heating and melting contacting edges of the segments to fuse them together. Moreover, the pair of segments is fixed to the elongated support element against movement in a longitudinal direction of the elongated support element. The elongated support element has a textured region of raised protrusions, indentations, or holes, over at least a portion of the surface thereof. Each cradle comprises a center portion located longitudinally between a pair of inclined portions.Type: ApplicationFiled: February 20, 2003Publication date: August 26, 2004Applicant: SIDERCA S.A.I.C.Inventors: Nelson Mario Pachao-Morbitzer, Guillermo Oscar Dapino, Hugo A.

Patent number: 6764108Abstract: An elongated drive string assembly includes a plurality of hollow sucker rods and connecting elements with an axis, connected together and between a drive head located at the surface of an oil well and a rotary pump located deep down in an oil well. Each hollow sucker rod has at least a first end including an internal female threaded surface engaging an external male threaded surface on a connecting element, such as a nipple. The first end also includes a torque shoulder, which engages a torque shoulder formed on the connecting element. The threads are frusto-conical, non-symmetrical threads with a differential diametral taper. The torque shoulders have a maximized mean diameter and cross-sectional area to resist storing reactive torque in the drive string. The nipple has a wall cross-section that increases towards the torque shoulders from each free end, to increase fatigue resistance.Type: GrantFiled: September 26, 2002Date of Patent: July 20, 2004Assignee: SIDERCA S.A.I.C.Inventors: Hugo A.

Each hollow sucker rod has at least a first end comprising an internal female threaded surface engaging an external male threaded surface on a connecting element, such as a nipple. In order to further optimize the stress distribution between the elements, frustro-conical, non-symmetrical threads with a differential diametral taper are used. The torque shoulders have a maximized mean diameter and cross-sectional area to resist storing reactive torque in the drive string. The nipple preferably has a wall cross-section that increases towards the torque shoulders from each free end, to increase fatigue resistance.Type: ApplicationFiled: September 26, 2002Publication date: May 8, 2003Applicant: SIDERCA S.A.I.C.Inventors: Hugo A.

Patent number: 6557906Abstract: A threaded union highly resistant to overtorque and compression that includes a threaded member in its internal surface—called female—that joins a threaded member in its external surface—called male—. The union between the male extreme and the female is produced through the threaded surface. When the members are fully assembled, one axially oriented surface in the free extreme of one of the members—called nose—presses against a corresponding surface in the other member—called shoulder of torque. This shoulder is comprised of two surfaces, a first one coincidentally oriented to the corresponding nose of the first member, and a second one truncated and conical in shape with an angle B and with the axis of the pipe located between the first surface and the internal cylindrical surface of the female member.Type: GrantFiled: September 20, 2000Date of Patent: May 6, 2003Assignee: Siderca S.A.I.C.Inventor: Gabriel Carcagno
