Ufuta-mpondo ungomunye wezinsiza-mvelo ezisebenza ngezindlela eziningi futhi ezibalulekile emhlabeni wanamuhla, okuhlanganisa konke kusukela ezimotweni kuye ezintweni zasendlini nemishini yezimboni. Inqubo yofuta-mpondo, kusukela ekwakhekeni kwawo ujule ngaphakathi koMhlaba kuze kube ukuguqulwa kwawo kube imikhiqizo esebenzisekayo, uhambo oluyinkimbinkimbi futhi oluthakazelisayo olubandakanya i-geology, i-chemistry, kanye ne-engineering. Ezinkampanini ezisebenza emkhakheni kawoyela negesi, ukuqonda lolu hambo akuyona nje into yezifundo—kubalulekile ukuthuthukisa ukukhiqiza, ukuthuthukisa ukusebenza kahle, nokuthuthukisa amasu esimeme. Lesi sihloko sihlinzeka ngokubuka konke okuphelele komjikelezo wokuphila ufuta-mpondo, okuhlanganisa ukwakheka ufuta-mpondo, inqubo yokukhipha uwoyela oluhlaza, ubuchwepheshe bokuhlanzwa, kanye nemiphumela yezomnotho neyemvelo yokuncika kuwoyela.

Indaba kaphethiloli iqala eminyakeni eyizigidi edlule ngokuqoqeka kwezinto eziphilayo ezifana ne-plankton, u-algae, nezinye izilwane ezincane kakhulu ezansi olwandle oludala. Ngokuhamba kwesikhathi, lezi zinsalela zezinto eziphilayo zimbekwa ngaphansi kwezendlalelo zenhlabathi, lapho ukushisa okwandayo nomfutho kuqala ukuguqulwa kwaba yi-kerogen futhi ekugcineni kube ama-hydrocarbon ayiketshezi. Ukwakheka kukaphethiloli kuyinqubo eyenziwa kancane, yemvelo edinga izinga lokushisa eliphakathi kuka-60°C no-120°C—isigaba esaziwa ngokuthi "i-oil window," lapho ngaphezu kwalokho kuvela igesi yemvelo. Le nkulungeko yokushisa, umfutho, nesikhathi yiyona nto eyenza ukuthi izindawo zikaphethiloli zitholakale ezindaweni ezithile zomhlaba kuphela. Bese inqubo yokukhipha uwoyela oluhlaza ihilela ukuguguda izinkulungwane zamamitha edwala ukuze kufinyelelwe kulezi zigcini eziboshiwe, ngokuvamile kudingeka izifundo eziphambili ze-geophysical nokuhlolwa kwe-seismic ukuze kutholwe kahle. Ukuqonda i-geology yokwakheka kukaphethiloli kusiza izinkampani ukuthi zibike ukuthi izindawo ezintsha zingatholakala kuphi nokuthi zingakhiwa kanjani ngempumelelo kakhudlwana.

Iwindi lamafutha liyingqiqo ebalulekile ku-geology kaphethiloli ngoba lichaza ubujulu nezinga lokushisa lapho ukukhiqizwa kwamafutha kukhiqiza kakhulu. Amadwala omthombo ajule kakhulu ahlala engavuthiwe futhi akhiqize amafutha amancane, kanti lawo ajule kakhulu abe sevedlule futhi akhiqize igesi eyomile. Leli "indawo emnandi" iyahlukahluka esifundeni kuye ngokushisa komhlaba kanye nohlobo lwezinto eziphilayo ezikhona. Izinkampani ezifana ne-河北凯源石油支撑剂有限公司, ezisebenza ngama-proppants asezingeni eliphezulu ukuze kuqhekekiswe ngamandla, zincike kulwazi lwale geology ukusiza abasebenzisi ukuthi bafinyelele amafutha abanjiswe ezindaweni eziqinile. Ama-proppants abalulekile ukuze kugcinwe iziqhekezi zivulekile emadwaleni e-shale namanye amadwala anomoya omncane, avumela ukuhamba kwamafutha negesi emgodini. Ngaphandle kokuqonda okuphelele ukwakheka kukaphethiloli nezimo ezidala izindawo zokugcina ezingenzeka, imizamo yokuhlola yayingaphumeleli kakhulu futhi ibe dula kakhulu.

Uma isiqongqothelana kaphethiloli esisebenza sesitholakele, isinyathelo esilandelayo ukukhipha uwoyela uye phezulu ngokuhlanganisa ukugawulwa, ukuqedwa komgodi, kanye nezinqubo zokukhiqiza. Inqubo yokukhipha uwoyela ongahluziwe ingahluka kakhulu kuye ngokuthi isiqongqothelana siyingqayizivele noma asiyona ingqayizivele, lapho lokhu kokugcina kuvame ukudinga ukugqashuka komoya ukuze kuthuthukiswe ukuhamba. Ekugqashukeni komoya, ingxube yoketshezi yamanzi, isihlabathi, kanye nezinye izinto zamakhemikhali iyominywa ngomfutho ophezulu ukuze kwakheke iziqhekeza edwaleni, futhi izinto zokubopha—izinhlayiya ezincane, ezijikelezayo ezenziwe nge-ceramic noma isihlabathi esihlanganiswe nge-resin—ziyominywa kulezi ziqhekeza ukuze zivuleke. Kulapho ubuchwepheshe bomkhiqizi njenge-河北凯源石油支撑剂有限公司 bubaluleke kakhulu, njengoba imikhiqizo yabo ithinta ngqo ukusebenza kahle kanye nokuphila isikhathi eside kwemigodi kawoyela. Le nkampani inikeza izixazululo ezahlukahlukene zokubopha ezihambisana nezimo ezahlukahlukene zesiqongqothelana, okuhlanganisa osayizi abenziwe ngokwezifiso kanye namandla enzelwe ukubekezelela imifutho emikhulu etholakala ejulile ngaphansi komhlaba.

Inqubo yokukhipha ayipheli ngokuhlukana; ibuye ihlanganise ukuhlukanisa uketshezi olukhiqizwayo—uwoyela, igesi, namanzi—phezu komhlaba nokulungisa lokhu ukuze kuthuthwe noma kulahlwe. Izindawo zokukhipha zesimanje zisebenzisa izihlukanisi, izishisisi, nezomisi zokucubungula uwoyela ongahluziwe ngaphambi kokuba ungene emapayipini noma ezithengeni zokugcina. Emithonjeni engajwayelekile, izinga lokukhiqiza lokuqala lingaba phezulu kakhulu, kodwa liyancipha ngokushesha, okwenza ukukhetha i-proppant kanye nomklamo wokuhlukana kubaluleke kakhulu ekwandiseni ukubuyiswa okuphelele. Izinkampani ezitshala ku-proppants esezingeni eliphezulu kanye nezinhlelo zokuhlukana eziklanywe kahle zivame ukubona amaprofayela okukhiqiza angcono kakhulu impilo yonke yomthombo. Ngokubambisana nomphakeli onokwethenjelwa njengoHebei Kaiyuan, abasebenzisi bangaqinisekisa ukuthi inqubo yabo yokukhipha uwoyela ongahluziwe iyasebenza futhi inenzuzo ngangokunokwenzeka, kunciphisa isikhathi sokungasebenzi nokuthuthukisa inzuzo yokutshalwa kwezimali.

Ngemva kokuthi uwoyela oluhlaza ukhiqizwe futhi uthunyelwe esitokisini samafutha, udlula uchungechunge lwezinguquko ezibonakalayo nezamakhemikhali ukuze kukhiqizwe izinsiza nezinto ezisebenzisa umnotho womhlaba. Isinyathelo esibaluleke kakhulu ukuhlukaniswa kukawolintshi oluhlaza, inqubo ehlukanisa ingxube eyinkimbinkimbi yama-hydrocarbon eziqeshini ngokusekelwe kumazinga azo okubilisa. Esigodini sokubilisa, uwoyela oluhlaza ushhiswa ube ngaphezu kuka-350°C, futhi njengoba umusi uphakama, uyancipha emazingeni ahlukene, ukhiqize imikhiqizo efana negesi yesitokisini samafutha, uphethiloli, i-naphtha, ukhisimusi, udayisi, uwoyela wegesi, kanye nowoyela ophelele. Isiqeshana ngasinye sinesigaba esithile samakhabhoni nezakhiwo ezichaza ukusetshenziswa kwaso - isibonelo, uphethiloli uqukethe izimolekyuli ezinamakhabhoni angu-4 kuya ku-12, kanti uwoyela ophelele uqukethe izintambo ezinamakhabhoni angu-20 noma ngaphezulu futhi usetshenziselwa ukushisa kwezimboni kanye nezinjini zasolwandle.

Nokho-ke, ukudiliza wodwa akukwazi ukuhlangabezana nesidingo esigcwele samikhiqizo elula, enenani eliphezulu njenge-gasoline kanye ne-diesel, ngoba uwoyela ongahluziwe ngokwemvelo uqukethe isilinganiso esikhulu sama-fractions asindayo. Kulapho ukudabuka (cracking) ekucwengeni uwoyela okubalulekile khona. Izinqubo zokudabuka zihlukanisa ama-molecule amakhulu e-hydrocarbon abe amancane, anenani eliphezulu ngokusebenzisa ukushisa (thermal cracking) noma ama-catalyst (catalytic cracking). I-Fluid catalytic cracking (FCC) kanye ne-hydrocracking yizindlela ezimbili ezijwayelekile eziguqula i-gas oil esindayo ibe yi-gasoline, i-diesel, kanye ne-propylene, zikhuphula kakhulu inani lemikhiqizo enenzuzo kusuka ebhodleleni ngalinye likawoyela ongahluziwe. Ngaphezu kwalokho, izinqubo zokubuyekeza (reforming) kanye ne-alkylation zithuthukisa isilinganiso se-octane se-gasoline futhi zikhiqize izingxenye zokuhlanganisa ezimafutha ahlanzekile. Ngokuhlanganyela, ubuchwepheshe bokucwenga buqinisekisa ukuthi inqubo kawoyela iletha inhlanganisela efanele yemikhiqizo ukuze kuhlangatshezwane nesidingo semakethe ngenkathi kwandisa inani lezomnotho kubacwengi.

Imikhiqizo ephuma ezindaweni zokucwenga kanye nezimboni zamakhemikhali ziningi kakhulu kunalokho abantu abaningi abakwaziyo, okudlula kude uphethiloli wedizili nezidizili ezishisisa izimoto. Amapulasitiki, izintambo ezenziweyo, izinto zokuhlanza, amafutha okugcoba, i-asphalt, amavawusi, ngisho nemithi konke kudabuka emafutheni aluhlaza. Ngokwesibonelo, ingxenye ye-naphtha evela ekuhlukaniseni okuyingxenye kwamafutha aluhlaza iyisisekelo esiyinhloko sezishisisi ezikhiqiza i-ethylene ne-propylene, izakhi ezakhelayo zamapulasitiki e-polyethylene ne-polypropylene asetshenziswa ezintweni zokupakisha, ezindwangu, izingxenye zezimoto, nemishini yezokwelapha. Ngokufanayo, i-kerosene icwengwa ibe uphethiloli wezindiza, kanti i-gas oil iba yidizili ne-heating oil. I-asphalt, ingxenye esindayo kakhulu, isetshenziselwa ukwakhiwa kwemigwaqo nokwenza uphahla, okubonisa ukuthi ingxenye ngayinye yebhodi inesicelo esibalulekile.

Izintambo ezenziweyo njenge-polyester, i-nylon, ne-acrylic nazo zitholakala kumakhemikhali asuselwa kuwoyela, okwenza imboni kawoyela ibe yingxenye ebalulekile emikhakheni yemfashini neyendwangu. Ama-lubricants namagrisi, anciphisa ukungqubuzana emshinini nasezintweni ezisebenzayo, enziwa kusuka emafutheni asetshenziswa lapho kuconwa khona uwoyela. Izinto zansuku zonke ezifana namakrayoni, amakhandlela, namathayi ziqukethe izinto ezitholakala kuwoyela. Inqubo yokuhlukanisa (cracking) ezindaweni zokucubungula uwoyela ayikhiqizi nje kuphela uphethiloli kodwa futhi idala ama-olefins nama-aromatics asetshenziswa emkhiqizweni omkhulu wamakhemikhali. Ezinkampanini ezisebenzisa lezi zinto—kungaba ekukhiqizeni, ekwakheni, noma ezintweni zabathengi—ukuqonda inqubo kawoyela kusiza ukulindela ukushintsha kwamanani, ukuphazamiseka kokuhlinzekwa, namathuba okuthuthukisa ezintweni ezisetshenziswe kabusha noma izinto ezizothatha indawo.

Imboni kaphethiloli iyisisekelo somnotho womhlaba wonke, esisekela imisebenzi eyizigidi futhi ikhiqiza izigidi zezigidi zamadola engeniso minyaka yonke. Uwoyela ubala cishe ingxenye yesithathu yokusetshenziswa kwamandla omhlaba wonke, futhi uhlala uyimithombo yamandla ebalulekile ezokuthutha, okubandakanya izimoto zomgwaqo, ezindizayo, kanye nemikhumbi. Ukubaluleka komnotho kaphethiloli kudlula amandla, njengoba amakhemikhali kaphethiloli atholakala kuwoyela ayizinto ezibalulekile kwezolimo (imichiza yokulima kanye nemithi yokubulala izinambuzane), ezempilo (imithi kanye namapulasitiki ezokwelapha), kanye nobuchwepheshe (izinto zikagesi kanye nezingxenye zamaphaneli elanga). Ukungazinzi kwentengo emakethe kawoyela kungaba nemiphumela eminingi kuzo zonke izinkalo, kuthinta izindleko, izilinganiso zokuhweba, kanye nezingxenye zezimali zikahulumeni emazweni akhiqizayo nawasebenzisayo.

Ezinkampanini ezibandakanyeka ngqo ekuhlinzekeni kwezinto zikadoti negesi—njengezinkampani zokuhlola nokukhiqiza, abacwengi, nabahlinzeki bezinsizakalo—ukuqonda okujulile kuyo yonke inqubo kaphethiloli kubalulekile ekuhleleni amasu nasekuphathweni kwezingozi. Izinkampani ezihlinzeka ngemishini nezinto ezibalulekile, njenge-河北凯源石油支撑剂有限公司, zizuzwa ngokufunwa njalo kobuchwepheshe bokukhipha obusebenzayo. Inkampani'sIMIKHIQIZOikhasi libonisa izinhlobonhlobo zama-proppants enzelwe ukuthuthukisa ukubuyiselwa kukadoti, kuyilapho i-Ucwaningo nentuthuko imizamo igxile ekuthuthukiseni izinto zesizukulwane esilandelayo ezisebenza kangcono ezimweni eziyingozi kakhulu. Ngokuhambisa ubuchule babo nezidingo zemboni kaphethiloli, abakhiqizi abanjalo basiza ukuqinisekisa ukuthi ukukhiqizwa kukaphethiloli oluhlaza kuhlala kungenzeka ngokomnotho noma ngisho nalapho izindawo ziba nzima kakhulu ukuzikhiqiza.

Ukusetshenziswa kabanzi kukaphethiloli kulethise izinselele ezinkulu zemvelo, okubandakanya ukukhishwa kwegesi elibangela ukufudumala komhlaba, ukuvuza kukaphethiloli, ukuphazamiseka kwezindawo zokuhlala, kanye nokungcola ngopulasitiki. Ukumbiwa, ukuthuthwa, ukucwengwa, nokushiswa kukaphethiloli konke kunomthelela ekushisweni kwekhabhoni okubangela ushintsho lwesimo sezulu, okwenza ukuguqukela emandleni ahlanzekile kube yinto ebalulekile emhlabeni wonke. Ngaleso sikhathi, umphakathi wanamuhla usalokhu uthembele kakhulu kukaphethiloli ukuze uthole imikhiqizo namasevisi abalulekile, ngakho-ke indlela ezayo kufanele ibalance izinhloso zemvelo nokuvikeleka kwamandla kanye nokuzinza komnotho. Iziyalezo zokugaywa kabusha kukapulasitiki, amazinga athuthukisiwe okusebenza kahle kukaphethiloli, kanye nentuthuko yamandla avuselelekayo (biofuels) kanye nezinye izindlela zokwenziwa konke kuyingxenye yomzamo wokunciphisa imiphumela emibi yokuthembela kukaphethiloli.

Ngaphakathi embonini kawoyela negesi uqobo, kunezindlela eziningi zokwamukela izindlela zokonga. Ngokwesibonelo, ukusebenzisa ama-proppant asezingeni eliphezulu avela kumkhiqizi ohlonishwayo njengeHebei Kaiyuan kungathuthukisa ukukhiqiza komthombo futhi kunciphise inani lemithombo edingekayo ukuhlangabezana nesidingo, ngaleyo ndlela kunciphise umthelela omkhulu wezemvelo wokusebenza kokukhipha.
