Abstract

U ovom radu razmatra se problematika testa porasta tlaka za višefazni protok nafte i plina u ležištu. Objašnjena su četiri različita pristupa tom problemu: korištenjem ukupnih svojstava fluida (metoda autora Perrine), pseudotlaka (metoda autora Raghavan), kvadrata tlaka (metoda autora Al-Khalifah) i relativnih propusnosti (metoda autora Kamala i Pana). Za svaki pristup dana je teoretska podloga i postupak dobivanja traženih rezultata. U svrhu vrednovanja navedena četiri pristupa izrađena su dva simulacijska modela ležišta cilindričnog oblika: jedan sadrži skin, a drugi ne. Simuliran je test porasta tlaka u simulatorskom programu Eclipse 100, te su dobiveni podaci koji se koriste za računanje propusnosti i skina analitičkim putem. Podaci iz programa Eclipse također su ulazni podaci za program Saphir (licenca #9643) koji se koristi u analizi rezultata testa porasta tlaka.

Abstract (english)

This paper deals with the issues of pressure buildup test for multiphase flow of oil and gas in a reservoir. Four different approaches to this problem are explained: using total properties of fluids (Perrine’s method), pseudo-pressures (Raghavan’s method), pressure squares (Al-Khalifah’s method) and relative permeability (Kamal-Pan’s method). The theoretical background and the process of obtaining the required results are given for each approach. For the purpose of the evaluation of the four approaches, two simulation reservoir models of the cylindrical form are made: one contains the skin and the other does not. A pressure buildup test was simulated in the Eclipse 100 simulation program and data obtained and subsequently used to analytically calculate permeability and skin. Data from the Eclipse 100 simulation program is also the input data for the Saphir program (licence #9643) which is used in the analysis of simulated buildup test results.
