Ityhubhu edibeneyo, eyaziwa ngokuba yi-flexible tubing, yenziwe nge-carbon alloy steel tubing ephantsi kunye nokuguquguquka okulungileyo ukuhlangabezana neemfuno zokuguqulwa kweplastiki kunye nokuqina okufunwa yimisebenzi ye-downhole.Imilinganiselo yetyhubhu ebhijelweyo esetyenziswa ngokuqhelekileyo zezi: Phi 1/2 ikota yesithathu ye-3/8 25.4mm, φ31.75mm, φ38.1mm, φ44.45mm, φ50.8mm, φ60.325mm, φ66.675mm, 2φ5mm, 2φ8mm .55mm, φ88.9mm, njl., amandla isivuno 55000Psi ~ 120000Psi.Iityhubhu ezidityanisiweyo, ezilimele kwirola kwaye zingamawaka aliqela eemitha ubude, zinokuthatha indawo yetyhubhu enemisonto eqhelekileyo ukwenzela imisebenzi eqhubekayo yokuphuma phantsi komngxuma ngoxinzelelo.I-tubing ehlanganisiweyo isetyenziswe ngokubanzi ekwembeni, ukugawulwa kwemithi, ukugqitywa, ukusebenza komsebenzi, kunye nangakumbi nangakumbi ekuhloleni i-oyile negesi kunye nophuhliso.
Nangona ilizwe lethu kwakudala laqala ukusebenzisa itekhnoloji yetyhubhu ephothiweyo kumsebenzi ophantsi komhlaba, kodwa ngenxa yempembelelo yezinto ezahlukeneyo isiphumo setekhnoloji yetyhubhu edityanisiweyo ayizange ifumane uluhlu olubanzi lophuhliso oludumileyo kwilizwe lethu, inqanaba lethiyori kunye nethekhnoloji xa kuthelekiswa nophuhliso oluphuhlileyo. amazwe kusekho umsantsa othile, okubangele ukusetyenziswa yokwenene kwinkqubo coiled ityhubhu ukusebenzisa ngokupheleleyo ukusetyenziswa inzuzo.Ukongeza, uninzi lomsebenzi ophantsi komhlaba kwilizwe lethu ukhona kusetyenziso lwetekhnoloji yetyhubhu ejiyiweyo ngobumfama, akukho sicwangciso sokwakha sineenkcukacha ngaphambi kokusetyenziswa, njengokusetyenziswa kwezixhobo kunye neendlela zetekhnoloji kunye nokusetyenziswa koluhlu, ukukhokelela kwitekhnoloji yetyhubhu edibeneyo isetyenziswa umsebenzi ophantsi komhlaba ukuguquguquka okuphantsi, itekhnoloji ethe gqolo ekusetyenzisweni kwesixhobo ayenzi iseti epheleleyo yeengxaki, ubunyani besixhobo Imeko yokusetyenziswa kwezizwe ngezizwe ibangela impembelelo ethile embi.
Ukuguga okudityanisiweyo kwezixhobo zetyhubhu eziphothiweyo
Okwangoku, uninzi lwezixhobo zetyhubhu ezidityanisiweyo ezisebenzayo zasekhaya zithunyelwa kumazwe angaphandle, izixhobo zibuyile umva, ezinye zide zafikelela kumhla wokugqibela wokulahlwa.Intloko yokutofa, isithinteli sokuvuthela, inkqubo yolwelo kunye nenkqubo yolawulo enxibe iinxalenye kunzima ukuyibuyisela kunye nokugcina.Uluhlu olufanelekileyo lwedayamitha yetyhubhu luncinci, ezinye iintshukumo ezikhethekileyo zomngxuma osezantsi azihlangabezani neemfuno zolwakhiwo.
Ukusetyenziswa kwetekhnoloji yetyhubhu ephothiweyo
Ukusetyenziswa kwe-gas lift yokubuyisela ioli
Itekhnoloji yokubuyisela i-oyile yokunyusa igesi kukufaka irhasi equleni kunye nokusebenzisa ukwanda kwerhasi ukunciphisa ukuxinana kolwelo oluxutyiweyo equleni, ukuze ioyile equleni iphume ngokulula.Ukusetyenziswa kwetekhnoloji yetyhubhu ephothiweyo kuye kwaphucula kakhulu ubungakanani bokubuyiselwa kweoyile ekrwada kunye nenqanaba letekhnoloji yokubuyisela ioyile.Kwiindawo ezininzi, igesi ye-ammonia ifakwe ezantsi komngxuma ngokusebenzisa itekhnoloji ye-tubing edibeneyo (CT) yokuphucula i-oyile kunye negesi.
Kwagrunjwa iMigodi emitsha ethe nkqo
Iityhubhu ezidityanisiweyo ezintsha Ii Wells zigrunjwa kusetyenziswa i-composite rig ene-top drive egrunjwa ngendlela eqhelekileyo ekuqaleni kokomba.Xa i-drill ifikelela kubunzulu obuthile, itshintshela kwi-coiled tubing drilling, emva koko inokuthi iqhube i-casing okanye igqibe umngxuma ovulekileyo.Ukugrunjwa okungathanga ngqo kubalelwa kuninzi lwe-ct Wells emitsha.
Iingenelo zokugrumba ama-Well amatsha kukhuseleko, ukugrumba okukhawulezayo (akukho khola), uthutho olulula, unyawo oluncinci, i-automation ephezulu kunye nokugcina abasebenzi.Okwangoku, isantya sokugrumba iityhubhu ephothiweyo phesheya sikhawuleza kakhulu.Kwiqula le-CBM elingama-700m ukuya kwi-1000m, kuthatha iintsuku ezi-4 kuphela ukusuka ekuhlelweni kwezixhobo zokomba ukuya ekususweni kwazo zonke izixhobo zokomba emva kokwakhiwa.IKhanada ngoku ngowona mmandla usebenzayo wehlabathi wokugrumba iityhubhu ezijiyileyo.
Ukusebenza kwe-Downhole kumasimi e-oyile kuyingozi, kwaye ukusetyenziswa kwetekhnoloji ye-tubing edibeneyo kufuna ubuchule kunye neemfuno ezingqongqo zokusebenza kwezixhobo.Ngokusebenzisa izixhobo ezahlukeneyo eziphambili ukwenza imisebenzi ye-downhole inokuphucula ngokufanelekileyo ukusebenza kakuhle, ukwenzela ukhuseleko lwabasebenzi bokwakha ukunika isiseko sesiqinisekiso.Nangona kunjalo, ukuze kuncitshiswe ixesha lokwakha, ukunciphisa iindleko kunye nokuphucula ingeniso, uninzi lwamashishini e-petroleum yaseTshayina luyaqhubeka nokuvuselela iteknoloji yokwakha ehambelanayo kunye nenkqubo, kodwa kwangaxeshanye, kusekho iingxaki kwimveliso yezixhobo, ukuze kwinkqubo. yokusebenza phantsi komhlaba, kukho ukunqongophala okukhulu kwezixhobo.Ukukhuthaza udumo olubanzi lwetekhnoloji yetyhubhu ephothiweyo, okokuqala kufuneka inkqubo ebanzi yezixhobo njengenkxaso, ukuze ilizwe lethu liqinise imveliso yezixhobo ezinxulumeneyo, ukwandisa utyalo-mali oluyinkunzi, ukwenza izixhobo ezifanelekileyo kunye nezibonelelo zokuhlangabezana nemfuneko yophuhliso kwi. ilizwe lethu, siphucule umgangatho wokusebenza kunye nokusetyenziswa kwezixhobo, ngaloo ndlela sibonelela ngesiseko sokuphunyezwa kwesiqinisekiso sobuchwepheshe betyhubhu ejiyileyo.
Ithemba lophuhliso lwetyhubhu ejiyileyo
Ukudibanisa ukusilela kokusebenza kwetyhubhu edityanisiweyo, kwinqanaba lokugqibela lophuhliso lwe-oilfield, thatha ukunyukela kobona buchwepheshe bugqwesileyo, ukuphucula isiphumo sokusetyenziswa kwetyhubhu edityanisiweyo, ukwandisa amathuba okusebenza kwetyhubhu edityanisiweyo, dlala isakhono sokusebenza kwetyhubhu edityanisiweyo, qinisekisa ukuphunyezwa okuyimpumelelo komsebenzi ophantsi komhlaba, ukunceda ukwenza kube ngcono kwimveliso ye-oilfield.
Ithemba lophuhliso lwetyhubhu ephothiweyo kwixesha elizayo lihlalutywa ukuze kuphuculwe inqanaba lokuzenzekelayo lezixhobo zokulawula umphezulu wetyhubhu ephothiweyo, ukunyusa rhoqo amanyathelo obuchule bokusebenza kwetyhubhu edityanisiweyo, ukuphucula isantya sokusebenza phantsi komhlaba kunye nokwakhiwa, ukunciphisa ixesha lokusebenza kunye ulwakhiwo, nokuqinisekisa ukugqitywa kakuhle komsebenzi ophantsi komhlaba kunye nolwakhiwo.Izixhobo zokuphanda i-downhole, yenza ukuba isebenzisane namanyathelo obuchwepheshe betyhubhu edityanisiweyo, iphucule inqanaba lokusebenza kunye nolwakhiwo lwe-Well ethe tye kwinqanaba lamva lophuhliso lwe-oilfield, thatha eyona ndlela ibalaseleyo yokuhlola kunye nokuvuselela itekhnoloji, ukuphucula imveliso yedama, ukuhlangabezana neemfuno zemveliso. uphuhliso lwe-oilfield.
Uphuculo oluqhubekayo lwemathiriyeli ephothiweyo yokutyhubhu, ukusetyenziswa kwezinto ezintsha kunye nobuchwepheshe obutsha kwitekhnoloji yokusebenza kwetyhubhu ejiyileyo, utshintshe i-diameter okanye utshintshe i-taper yesicelo setyhubhu ephothiweyo, ukusombulula iingxaki ezinzima zomsebenzi okhethekileyo womngxuma womngxuma.Ukusebenza ngokufanelekileyo komngxuma kunye nokwakhiwa kweMibhobho enzulu, ukunciphisa ukuguga kwityhubhu ephothiweyo kunye nokwandisa ubomi benkonzo yetyhubhu ejiyileyo.
