ANALYSIS OF \u00abSTICK-SLIP\u00bb TYPE TORSIONAL VIBRATIONS OF DRILL STRING AND ITS INFLUENCE FOR DRILLING PROCESS
<\/strong>Balitskiy Vladimir P., Cand. Tech. Sci., senior lecture, the chair of oil and gas drilling department of the Russian Gubkin State University of Oil and Gas, e-mail: Balitsky@gubkin.ru<\/strong><\/em>, Balitsky@gubkin.ru<\/a><\/em><\/strong>
Zaykov Dmitry L., 5-year specialist degree \u00abDrilling of Oil and Gas wells\u00bb Master student, Russian Gubkin State University of Oil and Gas, JSC \u00abSRPC GOT\u00bb Drilling Supervisor, e-mail: ZaykovDL@gmail.com <\/strong><\/em>ZaykovDL@gmail.com<\/a><\/em><\/strong><\/p>\n

\u0423\u0414\u041a 622.24

Key words:<\/strong> torsional vibrations, \u00abStick-Slip\u00bb phenomenon, PDC bits, vibrations, bit wear, reverse bit rotation.<\/p>\n

Oilwell drilling is often affected by self-excited \u00abstick-slip\u00bb vibrations, which can highly accelerate the wear of the PDC bits. The aim of the paper is to analyze the methodologies which allow to prevent the occurrence of these vibrations. This paper presents the new method which provides identical speed rotation of a bit.<\/p>\n
