Downhole tool for sealing well with non-flat profiles
A recently granted patent (Publication Number: US11959355B2) discloses a downhole tool designed for sealing wells. The tool comprises a push ring, a first slip ring, a first wedge, and a sealing element. The push ring and slip ring have non-flat profiles that prevent relative rotation, while the first wedge separates the slip ring into individual parts. The slip ring features initiating trenches and separation trenches that work in conjunction with ridges on the wedge to lock the slip ring in place. Additionally, the tool includes a second wedge, a second slip ring, and a mule shoe to further enhance the sealing capabilities of the tool.
Furthermore, the patent describes a method for assembling the downhole tool, ensuring the slip rings have uniform breaking parts. The method involves providing the push ring and slip ring with complementary non-flat profiles, placing them together to prevent rotation, and using the first wedge to separate the slip ring into individual parts. The process also includes locking the slip ring in place by engaging initiating trenches with corresponding ridges on the wedge. This innovative design and assembly method aim to improve the efficiency and effectiveness of downhole sealing operations in wells, showcasing advancements in wellbore technology.
