I-well yokuqala ishayelwe emoyeni kuphrojekthi yesigaba sesibili sokuthuthukiswa komthombo omkhulu wegesi waseChina onama-billion cubic meters ayi-100!

NgoJuni 9, umgodi wokuqala i-G10 weplathifomu ye-WHPG pilot yephrojekthi yokuthuthukiswa kwesigaba II yenkundla yegesi i-Bozhong 19-6, inkundla yegesi yokuqala eyizigidi eziyinkulungwane eziyikhulu zamamitha cubic e-Bohai Sea, uphumelele ngempumelelo, okubonisa ukuqala ngokugcwele komsebenzi wokuguguleka wephrojekthi yokuthuthukiswa kwesigaba II yenkundla yegesi.

Inkundla yegesi ye-Bozhong 19-6 condensate itholakala enkabeni ye-Bohai Sea, enejubane lamanzi eliphakathi kuka-20 amamitha. Kuze kube manje, ibonise izinto ezigciniwe zemvelo ezingaphezu kwezinkulungwane eziyinkulungwane eziyikhulu zamamitha cubic zegesi yemvelo kanye namamitha cubic angaphezu kwezigidi ezingama-200 kawoyela we-condensate. Iphrojekthi yokuthuthukiswa kwesigaba I yenkundla yegesi yaqala ukusebenza ngoNovemba 2023, futhi iphrojekthi yokuthuthukiswa kwesigaba II izokwakha amapulatifomu amasha amathathu ezindaweni zokuguguleka kanye nama-jackets amathathu.

Njengomsebenzi wokulandela kanye nokuthuthukisa ukuze kugcinwe ukukhiqizwa okuzinzile futhi kuthuthukiswe ukusebenza kahle kwephrojekthi yentuthuko yeSigaba I, iphrojekthi yeSigaba II igxila ekusebenziseni amathuba ezindawo ezijulile nokulandela intuthuko eluhlaza nehlakaniphile. Isebenzisa izimpumelelo ezinkulu kubuchwepheshe bokubhola ukuze kuguqulwe ngempumelelo izinto ezikhona zibe ukukhiqizwa, ngaleyo ndlela kuthuthukiswe isisekelo samandla olwandle sokuhlinzekwa ngamandla ahlanzekile esifundeni saseBohai Rim.

Ngokusekelwe kulwazi olutholwe ekuqhubekeni kokuqala, iqembu lephrojekthi yesigaba sesibili libhekane nezinselele eziningi zobunjiniyela nezobuchwepheshe, okubandakanya izendlalelo ezijulile kakhulu, izinga lokushisa eliphezulu nomfutho omkhulu, kanye namachibi angaphansi komhlaba ahlukanisile. Ngokuthatha umgodi u-G10 njengomgodi wokuhlola wobudlelwano bokubhola, le phrojekthi ihlinzeka ngesisekelo sezinto eziphilayo sokubhola okwenziwa ngezikhathi ezithile, ukuthuthukiswa kwezinqubo, nokubekwa kwemigodi okunembayo kwemigodi yokuthuthukisa eyi-19 endaweni yokuhlola, iqinisekisa ukuqhutshwa kahle kohlelo lonke lokubhola.

Kwi phrojekthi yentuthuko yeSigaba II, indawo eyinhloko inobunzima bokungcwatshwa obungaphezu kwamamitha angu-5,000, nokushisa okuphezulu kwesigingci esingaphezu kuka-200 °C kanye nomfutho omkhulu wokwakheka komhlaba. Ngokusekelwe ezimweni zesayithi, i-Boxi Regional Project Team ye-Engineering Technology Operation Center, i-Tianjin Branch, isisebenzise isu elihle kakhulu lokuguguleka elithi “umgodi owodwa, isu elilodwa; umnyango owodwa, isu elilodwa,” yathuthukisa imishini yokuguguleka, futhi yasebenzisana namayunithi amaningi ukubhekana nezinselelo zobuchwepheshe. Bakhe isistimu yokuguguleka enokumelana nokushisa okuphezulu nokulimala okuphansi eyenziwe ngendlela eyenzelwe le ndawo, bathuthukisa izindlela zokulawula ukulahleka kokujikeleza kanye nezindlela zokuvimbela umfutho ezindaweni ezahlukene, balawula ngokuqinile umehluko womfutho wokuguguleka, futhi balondoloza kakhulu iziteshi zokuphuma kwamafutha negesi.

Ukuhlelwa kwezimbobo endaweni yesikhululo i-WHPG kuminyene, okubeka izinselelo ezinkulu ekugwenzeni ukushayisana. Ithimba lephrojekthi lathuthukisa umklamo wokuhamba komgodi we-3D futhi lafaka isexwayiso sangaphambi kokushayisana esinamandla esigcwele ukuze kufezeke ukukhomba okunembayo izindawo ezincane. Bahlangabezana futhi nobuchwepheshe bokubeka usimende ezimbotsheni ezijulile nokugcinwa komgodi, besebenzisa usimende ongamelana nokushisa okuphezulu, okuncane okwandayo okuvimbela ukuhamba kwegesi ukuze kuqinisekiswe ikhwalithi enhle yokubopha umgodi yesikhathi eside.

Ezokusebenza kokuguguleka ezisekelweni ezintathu zama-wellhead zephrojekthi yokuthuthukisa i-Phase II, yonke inqubo ingahlanganiswa ohlelweni olulawulwa kude oluphakathi, oluvumela ukutholwa kwangempela kwemingcele efana nomthwalo wokuguguleka, i-torque, ingcindezi yepompo, kanye nezinga lokugeleza, kanye nesixwayiso sokuqala esihlakaniphile. Ubuchwepheshe bedijithali ngaleyo ndlela busebenzisa ukunciphisa ubungozi bezokuphepha obuhlobene nokusebenza okujulile.

Yethu Ukukhipha isihlabathi ku-condensate ekhiqizwe enkundleni yegesiiyidivayisi ephumelela kakhulu yokuhlukanisa uketshezi nokuqinile eyenzelwe ngokukhethekile ukwelapha ama-solids aqukethe i-condensate ehlukaniswe kuma-separator egazi-uketshezi. Ngokusekelwe kumgomo wokuhlukanisa we-cyclone, le mishini isusa ngempumelelo izinto ezingcolile eziqinile ezifana nezimvuthu, izinsalela, izinsimbi, isikali, namakristalu omkhiqizo kusuka kumidiya yoketshezi (uketshezi, igesi, noma ingxube yegesi-uketshezi). Izuza izinga lokususa elingu-98% lamapharele ≥5 microns, ixazulula izinkinga zokuvimbeka komgqomo nokuguguleka okubangelwa izinto ezingcolile eziqinile ezinhlelweni zokukhiqiza.
