Ukukhiqizwa kwephethiloli nsuku zonke kudlula izinkulungwane eziyishumi zamabhakede! Iphakheji yephakheji ye-Wenchang 16-2 iqala ukukhiqiza

Ku September 4, China National Offshore Oil Corporation (CNOOC) o phatlalatsa qalo ea tlhahiso projeke ea nts'etsopele ea letamo la oli la Wenchang 16-2. E fumaneha metsing a boroa ho Pearl River Mouth Basin, letamo la oli le eme ho botebo ba metsi bo ka bang 150 limithara. Morero o rerile ho ba le mekhahlelo e 15 ea nts'etsopele e kenang tlhahiso, ka tlhahiso e phahameng e khethehileng ea letsatsi e fetang 10,000 li-barrels tsa oli.

Ukuze kufezekiswe ukuthuthukiswa kwekhwalithi ephezulu kweWenchang 16-2 oil field, i-CNOOC yenza ucwaningo olunzulu kanye nokuboniswa ukuze kwakhiwe uhlelo lokuthuthukiswa kwesayensi. Ezweni le-geology, amaqembu omsebenzi enze ucwaningo olunzulu futhi athuthukisa ubuchwepheshe obuningi ukuze abhekane nezinselelo ezifana ne-reservoir encane, ubunzima bokuphakamisa i-crude, kanye nezimbobo ezihlukene. Ngokuqondene ne-engineering, iphrojekthi ibandakanya ukwakhiwa kwendawo ye-jacket entsha ehlanganisa imisebenzi efana nokukhishwa kwe-crude, ukucubungula ukukhiqiza, ukumbiwa nokuphothulwa, kanye nokwesekwa kokuphila kwabantu. Ngaphezu kwalokho, umgudu we-multiphase subsea ophakathi kuka-28.4-kilomitha ubude kanye ne-cable ye-subsea yamandla efanayo ubude baphakanyiswa. Ukuthuthukiswa futhi kusebenzisa izinsiza ezikhona ze-Wenchang oil field cluster eseduze.

Ngomhla kaSepthemba 2024, kwakhiwa iphothifoliyo ye-jacket. Le phothifoliyo iqukethe izingxenye ezine eziyinhloko: i-jacket, imodyuli ye-topsid, izindawo zokuhlala, kanye ne-modular drilling rig. Ngobude obuphelele obungaphezu kwama-200 metres kanye nesisindo esiphelele esingama-19,200 tonnes, iyisakhiwo esibalulekile endaweni. I-jacket iphakama cishe ngama-161.6 metres, iyenza ibe yi-jacket ephezulu kunazo zonke eNtshonalanga yeNingizimu China Sea. Izindawo zokuhlala zinezinhlelo ezisekelwe esikhumbeni, zisebenza njengezindawo zokuhlala ezijwayelekile zokuqala ze-CNOOC Hainan Branch. I-modular drilling rig, eyakhelwe ukuphila kwesevisi kweminyaka engama-25, ifaka imishini emisha enekhono lokuxwayisa ngezingozi ezingaba khona, ngaleyo ndlela ithuthukisa ukuphepha nokusebenza kahle kwemisebenzi yokubhoboza ezayo. Ngesikhathi sokwakhiwa kwephothifoliyo, ithimba lephrojekthi lathatha umklamo ojwayelekile, lahlanganisa ukuthengwa, futhi laqinisekisa izindlela zokwakha ezilula, kwehla isikhathi sokwakha sonke cishe ngenyanga ezimbili uma kuqhathaniswa nezinye iziphothifoliyo ezifanayo.

Ithuthukiswe ukumbiwa kwe-Wenchang 16-2 oilfield kwaqala ngokusemthethweni ngoJuni 23. Iqembu lephrojekthi lamukela ngenkuthalo umgomo othi "Ukumbiwa Okuhlakaniphile Nokufezwa KwezeMisebenzi" futhi lachaza le phrojekthi njengomzamo wokubonisa ukuthuthukiswa kwezobuchwepheshe nokuhlola izindlela ezinhle ngaphakathi kwesakhiwo se-"Smart and Optimal".

Prior to the commencement of drilling, the project team faced multiple challenges, including the complexity of shallow extended-reach drilling, potential fluid loss in buried-hill fractured zones, and difficulties in developing reservoirs with "gas atop and water below." Through comprehensive planning, the team conducted dedicated research on drilling and completion procedures, fluid systems, and intelligent well cleaning, ultimately establishing four adaptive technical systems. Moreover, the team completed all offshore installation and commissioning activities for a new modular drilling rig in just 30 days, setting a new record for installation efficiency in the western South China Sea.

Ngemuva kokuthi ukusebenza kuqala, ithimba lidlulisela emshinini ophumelelayo futhi ohlakaniphile, lehla ubunzima bokusebenza komzimba obukhulu ngama-20%. Ngokusebenzisa uhlelo lwe-"Sky Eye", ukuphathwa kokuphepha kokubona okungapheli kwafezeka. Ukwengeza uhlelo lokuhlola umud mud ngesikhathi sangempela kanye nezinsiza eziphezulu zokunemba kwathuthukisa kakhulu amakhono okuthola i-kick kusuka ezindaweni eziningi. Ngaphezu kwalokho, ukusetyenziswa okusha kokuhlukahluka kwe-oyili-manzi, i-synthetic drilling fluid engenamathambo kwathuthukisa ukusebenza. Njengomphumela, imithombo emithathu yokuqala yokuthuthukiswa iqediwe ngama-50% aphezulu ekusebenzeni, ngenkathi kugcinwa ukuphepha okuphelele kanye nekhwalithi yokwazisa kuyo yonke inqubo.

Koordinasi potensi operasional kapal rekayasa seperti "Hai Yang Shi You 202" (Minyak Lepas Pantai 202), pemasangan pipa bawah laut telah diselesaikan dengan efisien. Setelah penyelesaian dan aliran kembali dari tiga sumur pertama, minyak akan langsung diangkut melalui pipa ke ladang minyak Wenchang 9-7 yang dekat untuk diproses dan diekspor, berkontribusi untuk memastikan keamanan energi nasional.

It is reported that the Wenchang 16-2 oilfield is the first oilfield developed by CNOOC Hainan Branch, as the company previously focused solely on natural gas fields. This year, the company has set a challenge to "achieve oil production of ten million tons and gas production exceeding ten billion cubic meters," designating the Wenchang 16-2 oilfield as a "training ground" and "testing zone" to explore best practices under the "Smart and Optimal" framework, thereby enhancing the company's profitability and risk resilience.

Die Extraktion von Öl und Erdgas kann nicht ohne Desander erreicht werden.

Isebenzisa umshini wokuhlukanisa i-cyclonic desanding. Isebenzisa umqondo we-cyclone ukuhlukanisa izinto eziqinile, kufaka phakathi udaka, amatshe, ama-chips ensimbi, isikali, kanye nezinkanyezi zomkhiqizo, kusuka ku-gas yemvelo enokondensate & amanzi (izixazululo, igesi, noma ingxube ye-gas-liquid). Ihlanganiswe nobuchwepheshe obuhlukile obunamalungelo obunikazi be-SAGA, enezinhlobo ezihlukahlukene ze-liner (, isici sefilitha), eyenziwe ngezinto eziphakeme zobuchwepheshe eziphikisana nokugqwala (noma ezibizwa ngokuthi zihlala ziqinile) noma izinto eziphikisana nokugqwala ze-polymer noma izinto zensimbi. Umshini ophumelelayo wokuhlukanisa noma wokuhlukanisa izinto eziqinile ungaklanywa futhi wenziwe ngokuhambisana nezimo ezihlukahlukene zokusebenza, izinkambu ezihlukahlukene nezidingo zomsebenzisi. Ngemishini ye-desanding cyclone efakwe, umgudu ophansi we-sub-sea uvikelwe ekugqwaleni nasekuhlaleni kwezinto eziqinile futhi kwehla kakhulu imvamisa yokusebenza kwe-pigging.

Our high-efficiency cyclonic desanders, with their remarkable 98% separation efficiency for 2 microns particles removing, but very tight foot-print (skid size 1.5mx1.5m for a single vessel of D600mm or 24”NB x ~3000 t/t) for treatment of 300~400 m³/hr produced water), earned high acclaim from numerous international energy giants. our high-efficiency cyclone desander utilize advanced ceramic wear-resistant （or called, highly anti-erosion） materials, achieving a sand removal efficiency of up to 0.5 microns at 98% for gas treatment. This allows produced gas to be injected into the reservoirs for low permeability oilfield that utilizes miscible gas flooding and solves the problem of low permeability reservoirs development and significantly enhances oil recovery. Or, it can treat the produced water by removing particles of 2 microns above at 98% for directly re-injected into reservoirs, reducing marine environmental impact while enhancing oil-field productivity with water-flooding technology.

Umphezulu wethu uqhubeka nokuzinikela ekuthuthukiseni ama-desander aphumelelayo, ancane, futhi aphumelelayo kwezindleko ngenkathi sigxila ezintsha ezihambisana nemvelo. Ama-desander ethu eza ngezinhlobo eziningi futhi anemisebenzi ebanzi, njenge High-efficiency Cyclone Desander, Wellhead Desander, Cyclonic Well stream crude Desander With Ceramic Liners, Water injection Desander, NG/shale Gas Desander, njll. Ukuklama ngakunye kufaka izinguquko zethu zakamuva ukuze kuhanjiswe ukusebenza okuhle kakhulu ezinhlelweni ezahlukene zezimboni, kusukela ezinqubweni zokubhola ezijwayelekile kuya ezidingweni zokucubungula ezikhethekile.
