Abstract
|
This paper analyzes the non- rotating drill pipe wear tool works and downhole drill string mechanics , and established on the basis of the model of the mechanical analysis of the wear sleeve . And co-simulation using ANSYS and ADAMS to solve this problem . Text analysis of the contact pressure of the protective sleeve and the drill pipe , the friction torque and stress , and made ??a series of recommendations based on theoretical research results on the use of protective cover for drill pipe wear less off the protective cover in drilling application analyzes the mechanical boundary conditions of the protective sleeve . And using ADAMS software and ANSYS software co-simulation , dynamic simulation analysis on the problem of anti-wear sleeve in contact with the drill string and the borehole wall during drilling . And analysis of the friction of the work of the protective cover , exercise, stress , etc. . On this basis , less off anti-wear protection force condition sets in the drilling process was further analyzed and wear less protective cover off the wear and tear of its performance through the force changes . The paper also analyzes the protective sleeve with the drill pipe contact pressure and stress protective sleeve , and made ??a series of recommendations based on theoretical research results on the use of protective cover . Finally, a solution for protective cover wear prediction and life prediction .
