AI Technical Summary

Technical Problem

When opening windows in the casing, existing window opening tools are prone to frictional stagnation or positional deviation, resulting in reduced working accuracy and uneven pressure distribution, affecting the accuracy of window opening.

Method used

An ultra-short radius flexible window opening tool is designed, using a combination of auxiliary components, cleaning components and stabilizing components. The lifting block and downbar are driven to move simultaneously in the lifting groove through an electric push rod, and components such as cleaning arc head and rotating disc are used to reduce friction and improve stability.

Benefits of technology

It effectively reduces the friction between the window opening tool and the sleeve, ensures the stable positioning of the tool on the inner wall of the sleeve, and improves the accuracy and efficiency of the window opening.

Abstract

The invention discloses an ultra-short radius flexible windowing tool, and relates to the technical field of windowing tools. Comprising an outer sleeve-shaped tool string, an inner drilling tool string is arranged in the outer sleeve-shaped tool string in a penetrating mode, an auxiliary assembly is arranged at the inner bottom of the outer sleeve-shaped tool string, and the outer sleeve-shaped tool string is stably fixed in the inner wall of a casing pipe through the auxiliary assembly; a cleaning assembly is arranged on the auxiliary assembly, and friction between the external sleeve-shaped tool string and the sleeve is reduced through the cleaning assembly; a stabilizing assembly is arranged in the outer sleeve-shaped tool string, the stability between the auxiliary assembly and the sleeve is improved through the stabilizing assembly, and the cleaning assembly comprises a lifting groove formed in the outer sleeve-shaped tool string. Through cooperative use of the auxiliary assembly, the cleaning assembly and the stabilizing assembly, the window opening process of the window opening tool in the sleeve is effectively optimized, and higher stability, efficiency and precision are provided.
