20.500.12556/RUL-169096 Razvoj črpalne enote za črpanje surove nafte iz velikih globin Development of a pumping unit for the artificial lift of crude oil from great depths Z možnostjo vrtanja v vse večje globine so se pojavile nove priložnosti za pridobivanje nafte. Ocenjeno je, da trenutno več kot 90 % vseh naftnih vrtin za pridobivanje surove nafte potrebuje črpalni sistem oz.umetno dvigovanje. Trenutno se za črpanje uporabljajo relativno stare tehnologije, ki imajo precej pomanjkljivosti in naftnim podjetjem zmanjšujejo zaslužke. Zaradi tega velika naftna podjetja vlagajo v razvoj novih tehnologij, ki bi pomanjkljivosti odpravile. Ena od največjih pomanjkljivosti je nezmožnost ene same obstoječe tehnologije za pokrivanje pretokov skozi celotno uporabno dobo vrtine, zaradi česar je potrebno sprotno prilagajanje vrste tehnologije razmeram v vrtini, kar pa je zamudno in zelo drago. V prispevku je prikazan razvoj nove tehnologije črpalke, ki bazira na sicer obstoječih principih črpanja, vendar z inovativnimi konstrukcijskimi rešitvami omogoča, da se z združevanjem večjega števila črpalnih enot lahko zagotovijo ustrezni volumski pretoki in je ni treba kombinirati z drugimi vrstami črpalk. Zaradi zelo zahtevnih in specifičnih razmer v vrtini je bilo potrebno najti tudi številne tehnične rešitve za reševanje delnih funkcij. Serija prototipov je že bila testirana v vrtinah na globini tri tisoč metrov. Prvi rezultati so zelo vzpodbudni, pokazale pa so se tudi potrebe po izboljšavah in dopolnitvah. With the ability to drill to ever greater depths, new opportunities for oil production have emerged. It is estimated that currently more than 90% of all oil wells require artificial lifting. Currently, relatively old technologies are used for production, which have significant drawbacks that reduce oil companies’ revenues. For this reason, major oil companies are investing in the development of new technologies to address the shortcomings. One of the major drawbacks is that a single existing technology is not capable of covering the production flows throughout the life of the well, which requires constant adjustment of the technology type to the downhole conditions, which is time consuming and very expensive. The paper demonstrates the development of a new pumping technology based on existing pumping principles, but with innovative design solutions that allow combining multiple pumping units in one pumping system. This ensures sufficient maximum flow, which can be regulated to practically zero. Due to the very demanding and specific conditions in the well, it was also necessary to find a number of technical solutions to solve partial functions. A number of prototypes have already been tested in wells at a depth of three thousand meters. The initial results are very encouraging, but the need for improvements and additions has already become clear črpalke surova nafta abrazivni delci umetno dviganje črpalni sistemi pumps crude oil artificial lift abrasive particles pumping systems true false true Slovenski jezik Angleški jezik Članek v reviji 2025-05-12 09:12:11 2025-05-12 09:12:13 2025-05-13 04:01:26 0000-00-00 00:00:00 2023 0 0 Str. 182-193 št. 3 Letn. 29 jun. 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 621.52(497.4) 1318-7279 158765827 Oman_..._-Razvoj_crpalne.pdf Oman_..._-Razvoj_crpalne.pdf 1 B2BD062D8C104A4D2BC2F8B9FB5F996B 6b580239bfbf17ecf61e28ceb777c038d6ccf301a87c5471784f753dcd915555 edde5edf-2eff-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=210249 https://revija-ventil.si/razvoj-crpalne-enote-za-crpanje-surove-nafte-iz-velikih-globin/ 0 f7a8e4dc-2eff-11f0-b232-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=210250 Fakulteta za strojništvo Ventil 0 0 0
