一种自定位滑套开启工具及其使用方法
By designing a self-positioning sliding sleeve opening tool, automatic positioning is achieved by utilizing the length and shortness of the central tube of the sliding rail. This solves the problems of the sliding sleeve opening tool's inability to be accurately positioned and reused, improving construction efficiency and safety, and meeting the needs of unlimited sequential fracturing operations.

AI Technical Summary
Existing sliding sleeve opening tools cannot accurately locate the target sliding sleeve when opening the infinite cementing and fracturing sliding sleeve, resulting in operational errors, non-reusability, low efficiency of continuous operation, and well control risks.
Design a self-positioning sliding sleeve opening tool, including a conical upper connector, a slip assembly, a slip sleeve, a friction block groove, a locking cap, and a slide rail center tube. Automatic positioning is achieved through the design of long and short tracks on the slide rail center tube, ensuring that the tool does not open accidentally during the insertion of the sleeve, and the sliding sleeve is opened by lifting and lowering operations after reaching the target sliding sleeve position.
It achieves precise positioning for opening the sliding sleeve, avoiding opening failures due to operational errors or inaccurate positioning, improving construction efficiency and tool reliability, reducing well control risks, and allowing unlimited reuse to meet the requirements of fracturing operations in any sequence.
