Kwakabva Oiri Yakashata, Zvishandiso Mbishi uye Source Rock

Petroleum, inowanzonzi crude oil, inowana zita rayo kubva mumashoko echiLatin petra uye oleum. Petra zvinoreva dombo, nepo oleum zvichireva mafuta, zvichipa petroleum tsananguro yayo chaiyo semafuta edombo.

Mafuta asina kuchena anoramba ari akakosha chisikwa nekuti anopa simba rekufambisa, zviitiko zveindasitiri, kupisa, kugadzirwa kwemagetsi, uye kugadzira akawanda anobatsira petrochemical zvigadzirwa pasi rese.

Petroleum inowanzonzi “goridhe dema” nekuti mafuta asina kuchena anowanzoitika semvura yakasviba kana dema inobvira moto, kunyangwe chimiro chayo, viscosity, density, uye chimiro chemakemikari zvakasiyana pakati pemadhipoziti.

Kukosha kwepetroleum kunoita kuti mavambo emafuta asina kuchena Chidzidzo chakakosha mu geology, sainzi yezvemamiriro ekunze, zvidzidzo zvesimba, uye kuongorora peturu nekuti kuumbwa kwayo kunoda chaiwo biological uye geological mamiriro.

Masayendisiti akapa tsananguro dzakasiyana dzekuumbwa kwepetroleum, kunyangwe dzidziso yebiogenic inogamuchira kugamuchirwa kwakakura nekuti humbowo hwe geological, kemikari, uye hwehupenyu hunobatanidza mafuta akajairika neakare organic zvinhu.

Mavambo Dzidziso dzeCrude Oil

Masayendisiti akakurudzira dzidziso mbiri huru maererano ne mavambo emafuta asina kuchena: the biogenic theory uye abiogenic theory. Dzidziso imwe neimwe inopa tsananguro yakasiyana yekugadzirwa kwehydrocarbon.

Mafuta asina kuchena anowanikwa kubva munzvimbo dzakasiyana dze geological anowanzo siyana mukuwanda, sarufa yemukati, wax yemukati, viscosity, uye hydrocarbon kugovera, zvichiratidza kuti kuumbwa kwepetroleum kunoenderana neakati wandei geological zvinhu.

Misiyano iyi inoratidza kuti mafuta asina kuchena akagadzirwa kubva kwakasiyana tsime zvinhu uye akawana kwakasiyana kuvigwa, maturation, kutama, kuunganidza, uye shanduko nhoroondo mukati megeological petroleum masisitimu.

Kunzwisisa petroleum theories kunodawo ruzivo rwe zviwanikwa zvisingadzokerikezve, sezvo oiri isina kukora inokura kuburikidza nemaitiro eiyo geological anoshanda zvishoma nezvishoma kupfuura kushandiswa kwevanhu uye kutorwa.

Dzidziso idzi nokudaro dzinobatsira kutsanangura kuti peturu inobva kupi, kuti mahydrocarboni anokura sei, nei mafuta asina kuchena achisiyana, uye nei madhipoziti epetroleum achinyanya kuitika mumabheseni ane tsvina.

1. Biogenic Theory: Iyi dzidziso inotaura kuti yakajairika mafuta akashata akagadzirwa zvakanyanya kubva kune yekare zvinhu zvipenyu zvakaiswa mukati mesediments uye zvakashandurwa nekuvigwa, kupisa, kudzvanywa, uye geological nguva.

2. Dzidziso yeAbiogenic: Dzidziso iyi inokurudzira kuti ma hydrocarbons anogona kugadzirwa kubva kune inorganic kabhoni makomisheni kuburikidza neyakadzama geological reactions uye obva asimuka achikwira kumusoro kuburikidza nekutsemuka uye dzimwe nzira dzepasi pevhu.

3. Humbowo hweSainzi: Kucherechedzwa kweGeological, biomarkers, organic geochemistry, tsime-dombo hukama, uye petroleum maturation mapatani zvinopa tsigiro yakasimba yetsananguro yebiogenic yezvakajairwa petroleum kuumbwa.

4. Petroleum Systems: Mazuva ano petroleum geology inoongorora matombo, nzira dzekutama, matombo emvura, zvisimbiso, misungo, uye nhoroondo ye geological pamwe chete pane kubata kuumbwa kwemafuta asina kuchena sechiitiko chega.

Dzidziso yebiogenic inotsanangura mafuta asina kuchena sechigadzirwa chezvisaririra zvezvipenyu zvekare zvakaunganidzwa munzvimbo dzakaita sedimentary uye zvakachengetwa zvisati zvaora zvachose zvinogona kuparadza zvinhu zvavo zvehupenyu.

Marine plankton nealgae zvinopa zvakakosha petroleum precursors nekuti zvisaririra zvavo zvehupenyu zvinogona kuungana nekukurumidza mukati mesediments, kunyanya apo mwero weokisijeni unoramba wakadzikira zvakakwana kukurudzira kuchengetedza.

Zvidyarwa zvepanyika, tupukanana, uye zvipenyu zvakakura zvemumvura zvinokwanisawo kupa organic zvinhu. Huyero hwavo hunokanganisa chimiro chemakemikari epetroleum inozogadzirwa mukati medombo rekubva.

Kuumbwa kwemafuta efossil kunosanganisira nguva yakareba kwazvo ye geological panguva iyo yakavigwa organic matter inofambira mberi kemikari shanduko. Iyi nzira inosiyanisa petroleum kubva nokukurumidza replenished simba zviwanikwa.

Hukama pakati pezvipenyu zvekare nemahydrocarbons hunokurukurwazve kuburikidza nekuumbwa kwe hydrocarbon mafuta, kusanganisira crude oiri, gasi rechisikigo, uye mamwe carbon-based energy resources.

Sezvo kuvigwa kunoramba kuchienderera mberi, tembiricha nekumanikidza kunowedzera, zvichikonzera shanduko yemakemikari mukati mezvinhu zvakachengetedzwa zvakachengetedzwa. Shanduko idzi zvishoma nezvishoma dzinoburitsa kerogen uye pakupedzisira mvura kana gaseous hydrocarbons pasi pemamiriro ekukura akakodzera.

Biomarkers inopa humwe humbowo nekuti aya akaomesesa mamorekuru makomisheni anochengeta maitiro ane chekuita nebiological precursors uye anobatsira geologist kumisa hukama pakati pepetroleum nekwainotangira matombo.

Iyo yakafara geological kutevedzana kubva kune yakavigwa organic zvinhu kusvika kupetroleum yakakura inotsanangurawo kuti sei mafuta efossil achida mamirioni emakore kuti agadziriswe uye asingakwanise kukurumidza kutsiva zvakacherwa zvakachengetwa.

Abiogenic Theory uye Kugumira Kwayo

Dzidziso yeabiogenic inokurudzira kuti mamwe mahydrocarbons anobva kune inorganic carbon compounds mukati mePasi pane zvakananga kubva kumiti yekare, mhuka, algae, uye microorganisms.

Historical proposals yakakurudzira akati wandei inorganic mechanisms. Berthelot akakurudzira acetylene seyakakosha precursor, nepo Mendelejeff yakabatanidza chizvarwa chepetroleum nemaitiro anosanganisira esimbi carbides nemvura kana asidhi.

Vatsigiri vetsananguro yeabiogenic vanopokana kuti Pasi rine huwandu hukuru hwekabhoni uye kuti yakadzika geological mamiriro anogona kugadzira mahydrocarbons ayo anozosimuka achienda kunzvimbo dzisina kudzika.

Kutsemuka kwakadzika, kukanganisa, uye dzimwe nzira dze geological dzinogona kupa nzira dzekukwira kumusoro kwehydrocarbon kufamba pasi peiyi modhi, zvichibvumira mahydrocarbon anogadzirwa pakadzika kuti asvike pamisungo yakakodzera.

Nekudaro, sainzi yemazuva ano yepetroleum inowana humbowo hwakasimba hwezvinhu zvakasikwa, kunyanya mumafuta akajairwa ane hukama ne organic-rich sedimentary matombo uye anozivikanwa biological molecular siginecha.

Kuoma kunowedzera kujeka kana uchifunga zvakasimbiswa petroleum shanduko nzira, iyo inobatanidza kuvigwa kwezvinhu zvehupenyu, kuumbwa kwekerogen, kupisa kwemafuta, kugadzirwa kwehydrocarbon, uye kutama kunotevera.

Tsananguro dzeAbiogenic dzinosanganawo nematambudziko kubva kuzvidzidzo zve thermodynamic zvinoratidza kuti akawanda petroleum makomisheni haagadzirike kubva kumethane pasi pezvakajairwa sedimentary-rock pressure uye tembiricha.

Nekuda kweizvozvo, abiogenic maitiro anogona kutsanangura mashoma echisikigo hydrocarbon maumbirwo pasi pezvakadzama-Earth mamiriro, asi iwo haapi iyo inotungamira tsananguro yezvakajairwa petroleum kuunganidzwa.
