Abstract
A downhole tool for sealing a well includes a push ring, a first slip ring located adjacent to the push ring, a first wedge located adjacent to the first slip ring and configured to radially push the first slip ring and separate the first slip ring into individual parts, and a sealing element located adjacent to the first wedge and configured to seal the well. An upstream end of the first slip ring and a downstream end of the push ring form a wavy interface when in contact. The wavy interface locks the first slip ring relative to the push ring to prevent a rotation of the first slip ring relative to the push ring.
Claims19
A downhole tool for sealing a well, the downhole tool comprising:
- a central longitudinal axis;
- a push ring comprising a downstream end with a first profile that is non-flat relative to the central longitudinal axis;
- a first slip ring located adjacent to the push ring and comprising an upstream end with a second profile that is non-flat relative to the central longitudinal axis and complementary to the first profile, such that engagement between the first profile and the second profile prevents relative rotation of the push ring and the first slip ring;
- a first wedge located adjacent to the first slip ring and configured to radially push the first slip ring and separate the first slip ring into individual parts;
- and
- a sealing element located adjacent to the first wedge and configured to seal the well.
A downhole tool for sealing a well, the downhole tool comprising:
- a central longitudinal axis;
- a sealing element located adjacent to the first wedge and configured to seal the well;
- a push ring;
- a first slip ring located adjacent to the ring and comprising plural initiating trenches formed into a downstream end;
- a first wedge located adjacent to the first slip ring, configured to radially push the first slip ring and separate the first slip ring into individual parts, and comprising a smooth frustoconical body from which protrudes plural ridges;
- wherein the initiating trenches and the ridges are configured to lock the slip ring in place relative to the first wedge.
A method for assembling a downhole tool that has slip rings with uniform breaking parts, the method comprising:
- providing a push ring comprising a downstream end with a first profile that is non-flat relative to a central longitudinal axis of the downhole tool;
- providing a first slip ring comprising an upstream end with a second profile that is non-flat relative to the central longitudinal axis of the downhole tool and complementary to the first profile;
- placing the first slip ring adjacent to the push ring, such that engagement of the first profile and the second profile prevents relative rotation of the push ring and the first slip ring;
- placing a first wedge adjacent to the first slip ring, the first wedge being configured to radially push the first slip ring and separate the first slip ring into individual parts;
- and
- placing a sealing element next to the first wedge, wherein the sealing element is configured to seal the well.
