Abstract

Izrađen je simulacijski model za interpretaciju hidrodinamičkih testova, tj. protočnog testa i testa porasta tlaka, za nekoliko tipskih slučajeva protjecanja u pribušotinskoj zoni. Modeli su simulirani uz pomoć ležišnog simulatora Eclipse. Na temelju simulacijskih rezultata tlakova i protoka provedena je interpretacija hidrodinamičkih testova u programu Ecrin i analitički pomoću tabličnog kalkulatora (MS Excel). Uspoređivano je poklapanje ulaznih ležišnih parametara modela, prvenstveno propusnosti, s ležišnim parametrima koji se dobiju intepretacijom hidrodinamičkih testova kako bi se uskladilo petrofizikalne podatke pribušotinske zone u modelu. Na ovaj način pokazano je kako je moguće definirati heterogenu pribušotinsku zonu, ali i simulirati hidrodinamičke testove u vremenu duljem nego što se izvode hidrodinamički testovi u stvarnosti, što osobito ima potencijalnu primjenu za slabopropusne formacije.

Abstract: Reservoir simulation model has been made for pressure transient testing interpretation, i.e. flow test and pressure buildup test for a few typical cases of flow in near wellbore zone. Models were simulated with Eclipse reservoir simulator. On the basis of pressure and production simulation results, numerical well test interpretation was made by using software Ecrin and analytically by using spreadsheet calculator (MS Excel). Input model parameters, primarily permeability, were compared with reservoir parameters which were calculated from well tests. This was done in order to adjust petrophysical data of the near wellbore zone in the model. By doing this it was shown that it is possible to define heterogeneous permeability near wellbore zone, but also to simulate well tests for much longer period of time than it is usually done in practice. This especially has potential application for low permeability formations.
