Abstract

Primjena tehnike analize pouzdanosti dubinske opreme bušotine uvelike je pomogla pri
procijeni životnog vijeka opreme bušotine. Analiza pouzdanosti predstavlja postupak
kombiniranja komponenti pouzdanosti u sustav pouzdanosti, a izražava se kao vjerojatnost
s kojom će neki sustav obavljati svoju funkciju. Analiza pouzdanosti se pokazala kao
relativno sigurna metoda pri procjeni uspješnosti opremanja bušotine. Tehnika uključuje
logičke dijagrame za prikaz logičnog odnosa komponenti bušotine i daje podatke o stopi
neuspjeha na temelju poznatog poretka u pouzdanosti brtvljenja opreme bušotine. Podaci
dobiveni ovim putem omogućuju ocjenu samog sustava, što nije slučaj kod drugih analiza.
U radu je detaljno razrađena tehnika analize pouzdanosti na primjeru dubinskog
sigurnosnog ventila.

Abstract (english)

Abstract: Application of reliability analysis technique of downhole equipment has greatly helped to
evaluate well equipment life. Reliability analysis is a procedure of combining component
reliabilities into a reliability system. The reliability of a component or system of
components is the probability that it will perform its mission for a specified time interval
under actual use conditions. Reliability analysis has demonstrated the relative safety of
alternative well completions. The technique involves logic diagrams to depict the logical
relation of well components and has generated failure rate data by ranking well-component
seal reliabilities with respect to known values. Results have permitted a ranking of systems
that other types of analysis would not allow. The paper is outlined in detail in the example
of reliability analysis of the surface controlled subsurface safety valve.
