Abstract

Određivanje svojstava pribušotinske zone tj. proizvodnosti bušotine i istih svojstava nakon hidrauličkog frakturiranja ključan je element u dizajnu parametara za samo frakturiranje, kao i za planiranje tehnoloških uvjeta proizvodnje nakon frakturiranja. Dimenzije i provodljivost frakture mogu se predviđati analitički i numerički, a u radu su uspoređene analize, s naglaskom na hidrodinamički test nakon frakturiranja, interpretacijom krivulje porasta tlaka i njene derivacije (korištenjem software-a Kappa Ecrin) te modeliranjem istog testa i proizvodnih podataka u software-u Schlumberger Eclipse. Numerička simulacija u Eclipseu omogućuje procjenu više podataka poput oblika, položaja i rasprostiranja frakture različitih propusnosti i geometrije što se potvrdilo s proizvodnim podatcima i simuliranjem istih na temelju svakog pretpostavljenog seta parametara.

Abstract (english)

Determining near-wellbore zone properties i.e. well productivity and these same properties after performing hydraulic fracturing is the key element in fracturing design. Geometry and conductivity can be predicted both analytically and numerically, and in this work the comparison between analysis, especially for hydrodynamic test after fracturing, interpreting pressure build up curve and its derivative (using Kappa Ecrin software) and modeling the same test and production data in Schlumberger Eclipse software was done. It was concluded that numerical simulation in Eclipse allows prognosis for multiple parameters such as shape, position and fracture distribution of various permeabilities and geometry which has been validated with production data and simulations of this data based on each supposed set of parameters.
