20.500.12556/RUL-155315 Hidravlično lomljenje kamnin Hydraulic fracturing in rocks Tehnologijo hidravličnega lomljenja in tehnologijo vrtanja horizontalnih vrtin uvrščamo med starejše in ustaljene tehnologije. Metoda hidravličnega lomljenja v horizontalnih in vertikalnih vrtinah je učinkovita metoda pri pridobivanju nafte in plina. Od konvencionalnih metod pridobivanja nafte in plina se razlikuje zaradi hidravličnega stimuliranja vrtin. Hidravlično stimuliranje pri pridobivanju ogljikovodikov pa imenujemo nekonvencionalna metoda pridobivanja. Pri hidravličnem lomljenju uporabljamo hidravlični tlak, ki ga ustvarjamo z vbrizgavanjem hidravlične tekočine v vrtino. Pri visokovolumskem lomljenju se uporabljajo večje količine hidravlične tekočine kot pri nizkovolumskem lomljenju. Hidravlična tekočina je v veliki meri sestavljena iz vode, manjšega deleža propanta ter zelo majhnega deleža kemikalij. Hidravlično tekočino dodajamo direktno v vrtino in s pomočjo visokih tlakov omogočimo višjo permeabilnost (prehodnost oziroma prepustnost) rezervoarja. Tako omogočimo iztok ogljikovodikov iz rezervoarja v vrtino. S pomočjo javno zbranih podatkov sem predstavil zaloge na območju Petišovci-globoko (severovzhodna Slovenija) ter prikazal višjo proizvodnost plina v vrtinah na območju. Technology of hydraulic fracturing as well as the practice of drilling horizontal wells underground are both well-established methods with a long history. It is no surprise that the use of hydraulic fracturing has proven to be one of the most effective methods of extracting oil and gas from both horizontal and vertical wells. This method differs from the conventional oil and gas production because hydraulic stimulation takes place in the well. When hydraulic stimulation is employed to extract carbohydrates from a reservoir, it is known as an unconventional production method. Hydraulic fracturing is conducted by pumping hydraulic fluid directly into the wellbore. The high‑volume fracking method requires more fracking fluid compared to the low‑volume fracking method. Hydraulic fluid is largely composed of water, a small proportion of proppant and a very small proportion of chemicals. The hydraulic fluid, along with the high pressures generated, increases the permeability of the rock surrounding the borehole, creating fractures that allow the release of the carbohydrates trapped in the reservoir due to reservoir’s low or nonexistent permeability to the surface. With the help of publicly available data, I have been able to present some of the carbohydrate resources in the Petišovci-globoko area (northeastern part of Slovenia) and the increased gas production observed after the hydraulic fracturing method was conducted in the said area. hidravlično lomljenje konvencionalno nekonvencionalno peščenjaki severovzhodna Slovenija ogljikovodiki hidravlična tekočina propanti visoko volumsko lomljenje nizko volumsko lomljenje postopek hidravličnega lomljenja hydraulic fracturing conventional unconventional sandstones northeastern Slovenia carbohydrates hydraulic fluid proppant high volume fracking low volume fracking hydraulic fracking procedure true false false Slovenski jezik Angleški jezik Magistrsko delo/naloga 2024-03-26 09:00:04 2024-03-26 09:00:11 2025-02-25 08:29:13 0000-00-00 00:00:00 2024 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 2026-03-25 98181 191932419 20300.pdf 20300.pdf 1 DDA2E1FB0714ED2F8CC96CA9E9138AEF a8020daf9a01d0a5f2496289178b11cabe36c29d7cde30d6ed2d27c3c0a606c6 dff78f36-eb46-11ee-ab4b-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=182145 Naravoslovnotehniška fakulteta 0 0 0
