dc.description.abstractTokom rada na disertaciji ispitivana su 33 uzorka mogućih matičnihstena iz tri najznačajnije lokalne generativne depresije našeg dela Panonskogbasena: Banatsko Aranđelovo, Srpska Crnja i Zrenjanin. Devet ispitivanihuzoraka je bilo iz srednjeg miocena (baden i sarmat), 16 uzoraka je iz gornjegmiocena (panon i pont), sedam uzoraka iz nedefinisanog miocena (srednjimiocen ili panon) i jedan uzorak je nepoznate stratigrafske pripadnosti. Uzorcipotiču sa relativnih dubina od 1540 do 3420 m, na kojima temperature iznose88-175 °C. Ispitivano područje se odlikuje specifičnim geotermičkimkarakteristikama: povišenim geotermalnim gradijentom (4,0 – 7,5 °C/100m),toplotnim tokovima visokog intenziteta (90 – 110 mW/m2) i veoma velikimbrzinama zagrevanja sedimenata srednjeg i gornjeg miocena (9 – 22 °C/miliongodina).Osnovni predmet disertacije bio je definisanje zone generisanja nafte uPanonskom basenu Srbije, odnosno definisanje „naftnog prozora” na osnovudetaljnih geohemijskih istraživanja u kombinaciji sa već poznatim geološkimpodacima. Ciljevi ove teze bili su i utvrđivanje porekla, sredine taloženja izrelosti organske supstance ispitivanih matičnih stena, kao i utvrđivanjeprimenljivosti maturacionih parametara i jednačina za izračunavanje refleksijevitrinita za uzorke matičnih stena iz hipertermalnog basena. Na osnovukorelacije biomarkerskih parametara procenjena je i starost za sedam uzoraka iznedefinisanog miocena.Opšta karakterizacija organske supstance podrazumevala je elementarnuanalizu i Rock-Eval pirolizu, a refleksija vitrinita je korišćena za utvrđivanjeIzvodiistepena zrelosti kerogena. Rastvorna organska supstanca je izolovanaekstrakcijom po Soksletu (Soxhlet), a zatim je razdvojena na ugljovodonični deoi polarni ostatak. Za analizu individualnih biomarkera (n-alkani, izoprenoidnialifatični alkani, sterani i terpani) i aromatičnih jedinjenja (derivati naftalena,fenantrena i dibenzotiofena) primenjene su savremene instrumentalne metodegasna hromatografija sa masenom spektrometrijom (GC-MS) i gasnahromatografija sa tandemskom masenom spektrometrijom (GC-MS-MS).Organska supstanca je mešovitog drvenasto-algalnog porekla, pretežnosačinjena od kerogena tipa II. Taloženje organske supstance se odvijalo upromenljivim uslovima, od redukcionih do suboksičnih, pri čemu se salinitetpaleosredine postepeno smanjivao od srednjeg ka gornjem miocenu.Početak generisanja nafte odgovara temperaturi 110-120 °C i dubini od1850 do 2100 m, pri refleksiji vitrinita, Rc ≈ 0,53-0,58 %. „Naftni prozor“ dostižemaksimum na oko 145-150 °C, pri Rc ≈ 0,72-0,75 %, na dubinama od 2600 do2900 m. Kraj „naftnog prozora“ je na 170-175 °C, pri Rc ≈ 0,89-0,93 %, i dubiniod oko 3500 m. Izvedena je i aproksimativna kalibracija vrednostibiomarkerskih maturacionih parametara u odnosu na „naftni prozor“. Pri tomeje definisana i moguća primena dva, u organsko-geohemijskoj literaturi,relativno nova biomarkera, „rano eluirajućih“ hopana (čija struktura jepretpostavljena, ali ne i u potpunosti potvrđena) i C(14a)-homo-nor-17α(H)-hopana.Kada je reč o primenljivosti maturacionih parametara i jednačina zaizračunavanje refleksije vitrinita na uzorcima matičnih stena iz hipertermalnogbasena ustanovljeno je da su najprimenljivije jednačine zasnovane nasavremenoj temperaturi, steranskim i dibenzotiofenskim maturacionimparametrima i maturacionom parametru predloženom u ovoj disertaciji kojipredstavlja odnos C(14a)-homo-nor-17α(H)-hopana i C30 17α(H),21β(H)-hopana.Takođe, po prvi put su ustanovljene linearna i logaritamska jednačina kojepovezuju refleksiju vitrinita sa vrednostima steranskog maturacionogparametra C29ββ(R)/C29(ββ(R)+αα(R)).sr
dc.description.abstractIn this thesis 33 samples of potential source rocks taken from three mostimportant local generative depressions in the Serbian part of the PannonianBasin, Banatsko Aranđelovo, Srpska Crnja and Zrenjanin were investigated.Nine samples were from Middle Miocene (Badenian and Sarmatian), 16 werefrom Upper Miocene (Pannonian and Pontian), 7 samples were from undefinedMiocene (Middle Miocene or Pannonian) and for one sample age wasunknown. Samples were taken from relative depths from 1540 to 3420 m atwhich subsurface temperatures ranges from 88 to 175 °C, respectively. Theinvestigated area is characterized by specific geotermal characteristics: highgeothermal gradients (4.0 – 7.5 °C/100m), high heat flow (90 – 110 mW/m2) andthe exceptionally high heating rate of Middle and Upper Miocene sediments (9– 22 °C/Ma).The main objective of this thesis was to determine oil generation zone inthe Pannonian Basin in Serbia, i.e. to define “oil window” based oncomprehensive geochemical research in combination with already knowngeological data. The goals of this thesis were to determine the origin,depositional environment and maturity of organic matter of investigated sourcerocks, as well as applicability of maturation parameters and equations forcalculation of vitrinite reflectance for source rocks’ samples from ahyperthermal basen. The age of seven samples from undefined Miocene wasestimated based on correlation of biomarker parameters.General characterisation of organic matter was done by elementalanalysis and Rock-Eval pyrolysis, whereas vitrinite reflectance was used forAbstractvdetermination of kerogen maturity. The extractable organic matter was isolatedusing the Soxhlet method and then it was separated into hydrocarbons andpolar residue. For analysis of individual biomarkers (n-alkanes, isoprenoidaliphatic alkanes, steranes and terpanes) and aromatic compounds (derivativesof naphthalene, phenanthrene and dibenzothiophene) the modern instrumentaltechniques, gas chromatography-mass spectrometry (GC-MS) and gaschromatography-tandem mass spectrometry (GC-MS-MS) were used.The organic matter is of mixed woody-algal origin and consistspredominantly of Type II kerogen. Organic matter was deposited undervariable conditions from reducing to sub-oxic. Salinity of thepalaeoenvironment gradualy decreased from Middle to Upper Miocene.The oil generation begins at the temperature of 110-120 °C and % Rc ≈0.53-0.58 %, “oil window” peaks at ca. 145-150 oC and % Rc ≈ 0.72-0.75 %, and itends at 170-175 °C and % Rc ≈ 0.89-0.93 %, which corresponds to the relativedepths of 1850–2100 m, 2600–2900 m and ca. 3500 m, respectively. Anapproximate calibration of the values of biomarker ratios relative to “oilwindow” was proposed. The possible applicability of two relatively novelbiomarkers in organic geochemical literature “early eluting hopanes“, whichstructure is proposed - but not entirely proven, and C(14a)-homo-nor-17α(H)-hopane was established.Concerning the applicability of maturity parameters and equations forcalculation of vitrinite reflectance for the source rocks’ samples from ahyperthermal basin, the obtained results indicated that the most relevant areequations based on maximal palaeotemperature, sterane and dibenzothiophenematurity parameters and maturity parameter proposed in this thesis, whichrepresents the ratio of C(14a)-homo-nor-17α(H)-hopane and C30 17α(H),21β(H)-hopane. Also, linear and logarithmic equations, connecting vitrinite reflectanceand values of the sterane maturity parameter, C29ββ(R)/C29(ββ(R)+αα(R)), havebeen established for the first time.en
