Ukuhlola Uwoyela Negesi Kwasogwini: Okungenzeka, Inqubo, Nezinselele
Uwoyela negesi kuyimithombo ebalulekile yamandla ezweni lanamuhla. Naphezu kwemizamo yomhlaba wonke yokushintshela emandleni ahlanzekile navuselelekayo, uwoyela negesi kusalokhu kuyinsika yezomnotho wamazwe amaningi. Enye yezindlela eziyinhloko zokuthola lezi zinsiza ukuhlola ogwini lolwandle. Ukuhlola uwoyela negesi ogwini lolwandle kuhilela uchungechunge oluyinkimbinkimbi lwezinqubo ezihlose ukuthola, ukukhipha, nokukhiqiza ama-hydrocarbon ogwini lolwandle. Lesi sihloko sizohlola amandla, inqubo yokuhlola, kanye nezinselele ezibhekene nokuhlola uwoyela negesi ogwini lolwandle.
Amathuba Kawoyela Negesi Olwandle
Izilwandle sekuyisikhathi eside zaziwa njengomthombo omkhulu kawoyela negesi yemvelo. Ngokusho kombiko we-International Energy Agency (IEA), kufika ku-30% wokukhiqizwa kukawoyela emhlabeni wonke kuvela olwandle. Izindawo ezifana neGulf of Mexico, iNorth Sea, kanye ne-Atlantic Ocean ziyizindawo eziyinhloko zalolu cwaningo. Ngaphezu kwalokho, izindawo ezijulile nezijulile kakhulu, ezitholakala ekujuleni okungaphezu kwamamitha ayi-1.500, sezibe yindawo entsha yokuhlola uwoyela negesi.
Leli thuba liqhutshwa ukufika kobuchwepheshe bokubhoboza obuthuthukisiwe kanye nokuthuthukiswa kwamasu okuhlola i-geophysical, okwenza kube lula ukutholakala nokukhishwa kwama-hydrocarbon ezindaweni ezazingafinyeleleki ngaphambili. Intuthuko yezobuchwepheshe efana nokuthwebula izithombe zokuzamazama komhlaba ze-3D kanye ne-4D, ukubhoboza okuqondiswayo, kanye nobuchwepheshe bokulawula ngaphansi kolwandle kuvule amathuba amasha okuhlola amanzi ajulile.
Inqubo Yokuhlola Uwoyela Negesi Olwandle
Ukuhlolwa kukawoyela negesi olwandle kuhilela izigaba eziningana kusukela ekuhlolweni kwe-geophysical kuya ekukhiqizweni kokugcina.
1. Ucwaningo Lwezemvelo
Ukuhlolwa kwe-geophysical kuyisinyathelo sokuqala ekuhloleni ulwandle. Izazi ze-geophysic zisebenzisa izindlela zokuthwebula izithombe ze-seismic ukuze zidwebe isakhiwo esingaphansi kolwandle. Amagagasi e-seismic athunyelwa phansi kolwandle futhi ukubonakaliswa kwawo kuthathwe yizinzwa, okukhiqiza isithombe esiningiliziwe sezingqimba ze-geological ezingaphansi. Lezi zifundo zinikeza izinkomba zokuqala zezindawo ezingaba khona ze-hydrocarbon.
2. Ukumba Ukuhlola
Uma indawo engaba khona isitholakele, isinyathelo esilandelayo ukubhoboza ngokuhlola. I-rig yokubhoboza ibekwa endaweni, bese kusetshenziswa i-drill bit ukuhlola ukwakheka kwe-geological ngaphansi kolwandle. Amasampula edwala ayathathwa futhi ahlaziywe ukuze kutholakale ukuthi kukhona uwoyela noma igesi. Impumelelo kulesi sigaba ibalulekile ekunqumeni ukuthi indawo ifanele yini ukuthuthukiswa okuqhubekayo.
3. Ukuhlaziywa Nokuhlolwa
Uma ukumba okuhlolayo kuthola ama-hydrocarbon, isinyathelo esilandelayo ukuhlaziya nokuhlola. Lokhu kuhilela ukunquma inani lezinto ezigciniwe, ikhwalithi kawoyela negesi, kanye namathuba ezomnotho okumba okuqhubekayo. Idatha eqoqwe izosetshenziselwa ukuhlela izigaba zokuthuthukiswa nokukhiqiza.
4. Ukubhoboza kanye nokwakha
Uma imiphumela yokuhlola imihle, ukumba nokuthuthukiswa kwensimu kawoyela noma yegesi kuyaqala. Ingqalasizinda yangaphansi kolwandle efana nemithombo yokukhiqiza, amapayipi angaphansi kolwandle, kanye namapulatifomu okukhiqiza kwakhiwa. Lo msebenzi uvame ukuhilela imikhumbi yokumba eyinkimbinkimbi kanye namarobhothi angaphansi kwamanzi okufaka imishini ngaphansi kwamanzi.
5. Ukukhiqiza Nokunakekela
Uma yonke ingqalasizinda isikhona, ukukhiqizwa kukawoyela negesi kuyaqala. Lawa mafutha asetshenziswa emithonjeni yokukhiqiza aya ezindaweni zokucubungula, lapho uwoyela negesi kuhlukaniswa khona futhi kulungiselelwa ukuthunyelwa ogwini. Kuyo yonke ingqalasizinda, kwenziwa ukulungiswa okuvamile ukuqinisekisa ukusebenza okuphumelelayo nokuphephile.
Izinselele Ekuhlolweni Kwamafutha Negesi Olwandle
Nakuba amandla ezomnotho okuhlola uwoyela negesi ogwini lolwandle enkulu kakhulu, lo msebenzi awukhululekile ezinseleleni, kokubili kwezobuchwepheshe, ezemvelo kanye nezomthetho.
1. Izinselele Zobuchwepheshe
Ukuhlola nokumba emanzini ajulile kubhekene nezinselele zobuchwepheshe eziyinkimbinkimbi kakhulu. Ukujula kwamanzi, umfutho ophezulu, kanye nezimo zezulu ezimbi kakhulu konke kudinga ubuchwepheshe obukhethekile kanye nemishini. Ukulungisa umonakalo emishinini engaphansi kolwandle kungaba nzima kakhulu futhi kubize kakhulu.
2. Izinselele Zemvelo
Ukuhlolwa kukawoyela negesi ogwini lolwandle kunemiphumela ebalulekile kwezemvelo. Ukuchitheka kukawoyela kungabangela umonakalo omkhulu ezindaweni zemvelo zasolwandle. ukungcoliswa kwamanzi, umonakalo ezindaweni zokuhlala zasolwandle, kanye nemiphumela yokuzamazama komhlaba ngenxa yokumba nakho kuyizinto ezikhathazayo ezinkulu. Ngakho-ke, izinkampani zikawoyela negesi kumele zilandele izindinganiso eziqinile zemvelo futhi ziqhube imisebenzi yazo ngokuzibophezela.
3. Izici Zezenhlalo Nezomnotho
Imisebenzi yokuhlola olwandle ingaba nomthelela kwezenhlalo nakwezomnotho emiphakathini yasogwini. Ngakolunye uhlangothi, ingadala imisebenzi futhi ithuthukise umnotho wendawo. Ngakolunye uhlangothi, ingadala izingxabano nemboni yokudoba futhi iholele kwezinye izinkinga zomphakathi.
4. Imithethonqubo kanye Nezinqubomgomo
Ukuhlolwa kukawoyela negesi ogwini lolwandle kulawulwa yimithethonqubo eyahlukahlukene kazwelonke neyamazwe ngamazwe. Ukuthobela le mithethonqubo kubalulekile ekutholeni izimvume zokusebenza nokuqinisekisa ukuthi imisebenzi iqhutshwa ngokuphepha nangokuqhubekayo. Izinqubomgomo zamandla zomhlaba wonke ezisekelayo kakhulu amandla avuselelekayo nawo anamandla shintsha ukuguquguquka kwale mboni esikhathini esizayo.
Isiphetho
Ukuhlola uwoyela negesi ogwini lolwandle kuwumsebenzi oyinselele futhi ongase ube nomvuzo. Ngentuthuko yezobuchwepheshe kanye nolwazi oluthuthukisiwe lwe-geology, lokhu kuhlola kuvule amathuba amakhulu okuhlinzekwa kwamandla emhlabeni jikelele. Kodwa-ke, izinselele zobuchwepheshe, ezemvelo, ezenhlalo, kanye nezomthetho zidinga indlela eqaphile neqhubekayo yokuhlola.
Ukuqonda la makhono nezinselele kunikeza ukuqonda okujulile ngokubaluleka kokuthuthukisa ubuchwepheshe obusha , kanye nokubaluleka kwemikhuba yezimboni enomthwalo wemfanelo ekugcineni ibhalansi phakathi kwezidingo zamandla kanye nokusimama kwemvelo. Esikhathini samanje sokuguquka kwamandla, ukuhlola uwoyela negesi ogwini lolwandle kuzoqhubeka nokudlala indima ebalulekile ekuhlangabezaneni nezidingo zamandla zomhlaba wonke njengoba siqhubekela phambili ekusaseni elizinzile.
