Abstract

U diplomskom radu obrađena je tema plitkog plina s obzirom na opasnosti koje može izazvati tijekom bušenja uvodnog dijela bušotine. Objašnjena je pojava plitkog plina te su navedeni načini smanjenja rizika od erupcije kod bušenja kroz slojeve plitkog plina. Također su obrađeni i načini detekcije plitkog plina, s naglaskom na seizmička istraživanja. Objašnjeni su općeniti načini opremanja bušotine na kopnu i moru, ali i oni specifični za bušenje kroz slojeve plitkog plina. Posebna važnost pridodana je diverterskom sklopu kao najvažnijem dijelu opreme za kontrolu bušotine kod utoka plitkog plina. Pored toga, dan je primjer erupcija uzrokovanih plitkim plinom u Mađarskoj, uključujući naknadnu analizu promjena konstrukcije bušotine korištenjem simulatora, s ciljem sprječavanja takve i sličnih nesreća u budućnosti.

Abstract (english)

This thesis deals with the topic of shallow gas with regard to the danger that it poses during well-top drilling. The occurrence of shallow gas, as well as its definition is explained. In addition, the necessary precautions to reduce the risk of blowout during drilling through layers of shallow gas are listed. Shallow gas detection methods are discussed as well, and an emphasis is put on seismic surveys. The general well construction equipment for onshore and offshore wells is explained, as well as equipment specific for drilling through shallow gas formations. Particular attention is paid to the diverter system, which is the most important piece of well control equipment during shallow gas inflow. In addition, examples of blowouts caused by shallow gas in Hungary are given, including a subsequent analysis of the change in well construction in the simulator, with the aim of preventing such accidents in the future.
