Abstract

U radu je odabrano naftno polje s bušotinom X, za koju se provodi analiza povećanja proizvodnih mogućnosti projektiranjem mlazne crpke u programu Prosper (Sveučilišna licenca za edukativne svrhe: #4186). Prosper je računalni program tvrtke Petroleum Experts koji služi za postavljanje proizvodnih modela bušotine, te za dizajn i optimizaciju različitih proizvodnih sustava. Prednost uporabe ovog računalnog alata je velika točnost i brza obrada podataka, kao i mogućnost široke primjene u praksi. Bušotinu X karakterizira dugogodišnja proizvodnja, pa se tlak ležišta smanjio, a udio vode u kapljevini popeo na 80%, te bi uskoro došlo do prestanka njenog eruptivnog rada. Pri postavljanju proizvodnog modela bušotine potrebno je odrediti optimalan sustav proizvodnje dubinskom mlaznom crpkom za zadane uvjete u bušotini i ležištu. Proizvodno modeliranje se može podijeliti u nekoliko koraka, od unosa osnovnih ulaznih podataka za bušotinu s dubinskom crpkom, PVT karakteristika proizvodnog i pogonskog fluida, unosa podatka o opremi, kreiranja IPR i VLP krivulja, te konačnog odabira i dizajna dubinske mlazne crpke. Na kraju je provedena analiza osjetljivosti kako bi se odredile radne točke sustava tj. mogućnosti rada bušotine ukoliko bi došlo do daljnjeg povećanja udjela vode u proizvodnji, te za slučajeve ako bi se ležišni tlak nastavio smanjivati.

Abstract (english)

In this thesis, an oil field with Well X was chosen for analysis, focusing on enhancing production capabilities through the design of a submersible jet pump using the Prosper program (University license for educational purposes: #4186). Prosper, a computer program developed by Petroleum Experts, is employed for creating production models for wells and optimizing various production systems. The program stands out for its high accuracy, fast data processing, and versatile practical applications. Well X exhibits long-term production, leading to a decline in reservoir pressure and an increase in water cut in the fluid, reaching 80%. The objective is to establish an optimal production system with a submersible jet pump based on the well and reservoir conditions. The production modeling involves several steps, including entering basic input data for a well with a submersible pump, defining PVT characteristics of the production and power fluid, inputting equipment data, creating IPR and VLP curves, and ultimately selecting and designing the submersible jet pump. To explore further possibilities, a sensitivity analysis was conducted to assess well operation under potential increases in water cut during production and scenarios where reservoir pressure continues to decrease.
