Abstract
U radu je ukratko opisana teorija s osnovnim jednadžbama za analizu testova porasta tlaka, te je provedena analiza testa porasta tlaka vertikalne naftne bušotine, primjenom programa Saphir. Osnovni cilj je bio određivanje propusnosti stijene i skin faktora, a u svrhu dobivanja što pouzdanijih rezultata, analizirana su tri slučaja, ovisno o PVT svojstvima fluida. U 1. slučaju je pretpostavljeno da je fluid jednofazan, u drugom da je dvofazan i u trećem da je višefazan. Iako iz metode tzv. log-log dijagrama u sva tri slučaja nije dosegnut tzv. neograničeno djelujući radijus, jer nije došlo do potpunog preklapanja mjerenih i modeliranih krivulja, rezultati se prema opisima u diskusiji mogu uzeti s dovoljnom pouzdanošću. Najpouzdaniji rezultat dobiven je u 1. analizi, te je propusnost ležišne stijene određena u iznosu od 0,18 mD (1,78*10-16 m2), a pripadajući skin faktor iznosi 3.7.
Abstract (english)
The thesis briefly describes the theory with the basic equations for pressure build up test analysis. The analysis of the vertical oil well was performed using the Saphir program. The main objective was to determine the permeability of the rock and the skin factor. In order to obtain the most reliable results, three cases were analysed, depending on the PVT properties of the fluid. In the first case it was assumed that the fluid is single-phase, in the second case it is two-phase and in the third case it is multiphase. Although from the so-called method of log-log diagram in all three cases the so-called transient period was not achieved, because there was no complete overlap of the measured and modelled curves, the results can be taken with sufficient accuracy according to the descriptions in the discussion. The most reliable result was obtained in the first analysis. The permeability of the rock was determined to be 0.18 mD (1,78*10-16 m2), and the corresponding skin factor is 3.7.
