Abstract

Zadatak diplomskog rada bio je analizirati petrofizikalne karakteristike ležišta pomoću bušotinskih podataka naftnog polja Dugo Selo te promotriti analize rezultata testiranja ležišta. Na temelju toga, procijenjena je mogućnost revitalizacije bušotina za korištenje geotermalne vode uz sezonsko skladištenje toplinske energije u zavodnjenim slojevima. Na odabranoj mikrolokaciji izvedeni su proračuni dinamičkog tlaka korištenjem programskog paketa WellPerform, koji je dizajniran za analizu gradijenata tlaka u bušotinama u odnosu na protok, vrstu fluida, udio otopljenog plina, karakteristike ležišta i tehničkih parametara bušotina. Svrha korištenja softvera bila je da se dobiju IPR krivulje koje omogućavaju proračun dinamičkih tlakova pri određenim protocima kod dugoročne proizvodnje i sukladno tome odredi položaj električne potopne pumpe. Koristeći se podatcima potrošnje električne pumpe i visine dizanja napravljen je proračun potrošnje električne energije sukladno dubini smještaja. Gringartenovim obrascem i Ramey-Nabor metodom procijenjeno je trajanje izotermne proizvodnje za proizvodno-utisni scenarij.

Abstract (english)

The task of the master's thesis was to analyze the petrophysical characteristics of the reservoir using well data from the Dugo Selo oil field and to review the analysis of reservoir test results. Based on this, the possibility of revitalizing the wells for the use of geothermal water with the potential for seasonal thermal energy storage in water-saturated layers was assessed. At the selected microlocation, dynamic pressure calculations were performed using the WellPerform software package, which is designed to analyze pressure gradients in wells in relation to flow, fluid type, dissolved gas content, reservoir characteristics, and technical well parameters. The purpose of using the software was to obtain IPR curves that allow the calculation of dynamic pressures at specific flow rates for long-term production, and based on these, determine the position of the electric submersible pump. Utilizing the electric pump consumption data and the lifting height, an electric energy consumption calculation was made according to the installation depth. Gringarten's model and the Ramey-Nabor method were used to estimate the duration of isothermal production for the production-injection scenario.
