Studies of Equipment Stability for Drill String in Oil Fields Development

Abstract

The current development state of oil and gas fields is characterized by the share increase of hard-to-recover reserves, which leads to new technological solutions for bottom-hole layouts during construction of directional wells. The paper presents analytical studies of the oscillator-turbulizer, and static equations for the initial and closed position of the valve. The results can be further used to develop various designs of hydraulic vibrators for drilling.
