APPLICATION OF MATHEMATICAL AND PHYSICAL MODELING FOR DEVELOPMENT OF TECHNOLOGY OF ELIMINATION OF CLAMPS BY VIBRATION

Abstract

Clamp elimination is one of the most laborious kind of works. Thus, there is a work on creation and modernization of equipment and technologies allowing to facilitate this type of works. The article is about modeling work of vibratory impact mechanism designed to extract stuck pipes by small-fragmental rocks (sand) for drilling and workover. The article shows the difference between vibration devices of stressed and unstressed effect compared the principles of their actions. There is described an experiment conducted by the physical models of device of creation of mechanical oscillations of stressed and unstressed effect. Experimentally confrmed greater effciency of vibratory impact machines is shown. Mathematical work of vibratory impact machine based on wave theory of stroke and strength calculations is presented. The model allows to determine frequency boundaries at which op-eration of the vibratory impact machine will be safe.
