Abstract

U ovom je radu opisana samo ona oprema koja je vezana za osiguranje ušća bušotine odnosno koja sprječava nekontrolirani dotok slojnog fluida iz bušotine. U prvom dijelu ovog rada opisani su sastavni dijelovi i radne karakteristike protuerupcijskih uređaja proizvođača Cameron, Hydril i Shaffer koji predstavljaju sigurnosnu opremu na velikoj većini bušaćih postrojenja. Uspoređena su konstrukcijska rješenja, tehničke karakteristike i operativne mogućnosti prstenastih i čeljusnih preventera. Nadalje, detaljno su prikazana konstrukcijska rješenja, tehničke karakteristike i operativne mogućnosti rotacionih preventera i divertera. U drugom dijelu rada prikazani su unutarnji preventeri koji sprječavaju dotok slojnog fluida kroz bušaći alat. Prikazana su konstrukcijska rješenja, tehničke karakteristike i operativne mogućnosti osnovnih tipova zasuna na radnoj šipki i protupovratnih ventila bušaćih šipki.

Abstract: This degree essay gives detailed description of safety devices (blowout preventers) which prevents uncontrolled flow of well fluids from wellbore to surface. Safety devices presented in this thessis are annular and ram blowout preventers, diverters, rotating heads and equipment for closing off drillpipe which includes safety valves, floats and inside blowout preventers. Major components and principle of work for all listed devices are thoroughly described. In first part of this essay, there is detailed description of safety devices from major equipment manufacturers Cameron, Hydril and Shaffer which represents safety equipment on most of the drilling rigs. Also, there is comparison of design and working principle annular and ram preventers. In the other part of this essay, equipment for closing off drillpipe is presented with their difference in design and principle of work.
