Analysis of Mathematical Models for Developing a Methodology to Measure Energy and Spatial Characteristics of Axial Impact During Well Drilling

The article highlights the shortcomings of the measuring systems used in rotary drilling today. In the course of analyzing the existing developments and research in the field of monitoring and controlling of the dynamic load on the bit, it was concluded that there are no measuring systems that provide an objective assessment of the amplitude of longitudinal vibrations. Mathematical models describing the dynamics of rotary drilling of wells were analyzed and the need to determine the amplitude for an objective assessment of the dynamic component of the actual load on the bit during drilling was established. The dependencies describing the behavior of compressible fluids during impact are considered. A methodology for measuring the amplitude of longitudinal vibrations during well drilling is proposed, and a laboratory stand is developed for adjusting and confirming the proposed methodology.
