ВИЗНАЧЕННЯ ЧАСУ ПІДНІМАННЯ КОЛОНИ БУРИЛЬНИХ ТРУБ ПРИ СПУСКО-ПІДНІМАЛЬНИХ ОПЕРАЦІЯХ

Abstract

The article is devoted to determination of time of getting up of column of boring pipes at tripping on boring options. Actuality of question is proved and the lacks of method of timing getting up of column of boring pipes existing presently on the coefficient of filling of the tahogrammi getting up are analysed. A new method of determination of time of getting up of column of boring pipes which is based on the decision of equalization of motion of column of boring pipes is offered. Theoretical research of dependence of time of getting up of column of boring pipes from tractive force of engines of power drive is conducted weights of part of the talevoy system carrying out reverse-forward motion and loading on a hook from weight of boring column.
