Abstract

Prikupljeni su publicirani podatci iz različitih izvora o geotermalnom polju Velika Ciglena. Podatci su poslužili za izradu dva bazna simulacijska modela različitih dimenzija u simulatoru Eclipse. Služeći se pretpostavkama iz istih publikacija, rađena je analiza osjetljivosti na dimenzije ležišta, vodljivost frakture, propusnost te propusnost ležišta nakon frakturiranja. Protoci na proizvodnoj i utisnoj bušotini bili su ulazni podatak za dizajn postrojenja s organskim Rankineovim ciklusom (ORC) koji je modeliran pomoću softvera Aspen Plus i u kojem su posebno razmatrani pentan i butan kao sekundarni radni fluid. Pokazalo se kako je perspektivna tehnologija istovremenog skladištenja i iskorištavanja utisnutog CO2 kao geofluida (CCUS), tj, primarnog fluida u ORC postrojenju.

Abstract (english)

Published data from various sources on the geothermal field Velika Ciglena has been collected to create two basic simulation models of different dimensions in the Eclipse numerical simulator. Using assumptions from the same publications, the sensitivity analysis was carried out on the dimensions of the reservoir, the conductivity of the fracture, the permeability, and the permeability of the reservoir after fracturing. Flow rates on production and injection wells were the input data for the design of an organic Rankine cycle (ORC) plant modelled using the Aspen Plus software, in which pentane and butane were considered as secondary working fluid. It has been shown that the perspective technology of simultaneous storage and utilization (CCUS) of CO2 as geofluid i.e., primary fluid in the ORC plant exists.
