Analysis of Dynamic Load Capacity of the Top Drive of Drilling Rigs

Resumo

Problems related to the occurrence of undesirable oscillations in the course of drilling deep oil and gas producing wells with the use of a top drive are presented. An example of a mathematical model is presented in order to demonstrate the quantitative characteristics of pulsations in the tool. The results of the study consist of recommendations for use in determining the design load on the motor of a top drive and in processing experimental data on the drilling process.
