Дослідження знако-змінних навантажень у бурильних трубах під час спуско-підіймальних операцій

Abstract

Modeling the prototype elevator drill and string coupling was made by using Simulation Module Solid Works. The configuration parameter sand field strength inside equipment at a load of 2500 kN and 3000 kN was found. It is shown that the problem of reducing the load on alternating drill pipe during tripping operations can be solved by change in the geometry of the elevator stop sand coupling.
