EXAMPLE OF EQUIPMENT DESIGN BY ASSESSING THE TECHNICAL CONDITION OF SEALING ELEMENTS OF ANTI-BLOWOUT MECHANISM

The materials of the article consider examples of calculations and selection of technical solutions for modernization of the design: the spot preventer was improved by establishing an indicator by which the position of the preventer piston can be observed; the reliability of the anti-blowout equipment used in well drilling was assessed. When introducing the modernized design of the universal preventer, the reliability of operation, the service life between overhauls, durability and maintainability of the preventer are increased. The reliability of the obtained results is evidenced by their mutual consistency, correspondence to the literature data, correlation of theoretical calculations with the results of experimental studies and positive results of industrial tests. The obtained results correlate with previously known ones, which confirms the validity of the scientific provisions, conclusions and recommendations formulated in the work.
