錯斷井組合鉆具力學(xué)分析
[Abstract]:With the continuous extension of the production time of oil and water wells and the influence of production and development schemes, different geological and engineering conditions, the casing technical conditions in oil and water wells are gradually becoming worse, casing deformation and failure occur, etc. A repair method is needed to restore the casing damaged well to production. Aiming at the workover technology of casing failure and squeezing compression diameter, considering the two kinds of drill bit structure forms, grinding shoes and milling cone, the relationship between drilling pressure, torque and other loads is deduced by simplifying and analyzing the mutual cutting mode between bit and casing damage pipe. The nonlinear transient dynamic analysis model of combined drilling tools, such as the structure of combined drilling tools, the collision contact between drilling tools and casing, and various external loads, is established, which makes the working state of drilling tools in the downhole reasonably described. The dynamic gap element theory is used to describe the collision contact problem between drilling tool and casing, and the dynamic analysis equation of space beam element is used to solve the dynamic problem of drilling tool by NEWMARK method. It provides an effective calculation method for transient dynamic analysis of workover drilling tools. Based on the established model and theoretical method, the dynamic analysis software is compiled to analyze the dynamics of two kinds of combined drilling tools, which have flat sole grinding shoes and high efficiency milling cone, and obtain the stress deformation of combined drilling tool and the contact collision state of casing inner wall. The motion state of the combined drilling tools and the evaluation of the results of laboratory experiments and dynamic analysis provide a theoretical basis for the combination design of the workover string and the selection of technological parameters for the staggered well workover.
