Ufuna nini uQhagamshelwano lwePrimiyamu ye-API 5CT Casing kunye neTubing?

Kwisicwangciso esilungileyo,ibhokisikwayeimibhobhoiintambo zibukeka zilula: OD, ubunzima, ibakala, ukukhukuliseka. Kwintsimi, ukuvuza kunye neengxaki zengqibelelo phantse azizange ziqale kumzimba wombhobho - ziqala ngokudibanisa.

I-API 5CTngumgangatho ongundoqo we-casing kunye ne-tubing: ichaza amabanga, imilinganiselo kunye neefom zemisonto eziqhelekileyo ezifana ne-STC/LTC/BTC ye-casing kunye ne-NUE/EUE ye-tubing. Kwimithombo emininzi yeoli eqhelekileyo, olu dibaniso lwe-API luseyimpendulo eyiyo. Kodwa kwimithombo yegesi enoxinzelelo oluphezulu, umsebenzi we-HP/HT, amacandelo amade axwesileyo kunye namaqula ahamba ngebhayisekile kakhulu, iziko lomngcipheko liyatshintsha ukusuka kumzimba wentsimbi ukuya kuyilo loqhagamshelo. Kulapho unxibelelwano olukhethekileyo / lweprimiyamu lungena khona.

I-API 5CT kunye ne-API 5B ichaza ezona ntsapho ziphambili zomsonto we-casing kunye ne-tubing:

Casing

• I-STC – Imisonto emifutshane idityanisiwe (umjikelo omfutshane)
• I-LTC-Imisonto emide idityanisiwe (umjikelo omde)
• I-BTC-I-Buttress Thread Coupled

Ityhubhu

• I-NUE-Isiphelo Sokungacaphukisi
• I-EUE - Ukuphela kokuphazamiseka kwangaphandle

Olu nxulumano luqhelekileyo lu:

• Yomelele ngokwaneleyo (uxinzelelo, uxinzelelo, itorque) kumhlaba omninzi kunye namaqula aqhelekileyo
• Ingabizi kakhulu kwaye ifumaneka ngokubanzi
• Iqhelekile kwi-rig crews, ene-ecosystem epheleleyo yezinto ezihambelanayo

Kodwa kukho iinyaniso ezimbini ezingathandekiyo:

• Imisonto engqukuva ye-API (STC/LTC) ayizange iyilelwe ukuba iqine ngokugqibeleleyo kwigesi kuxinzelelo oluphezulu; bathembele kakhulu kwintambo edibeneyo kunye nokuphazamiseka.
• Nkqu ne-BTC ibeka phambili umthamo wesakhiwo kuqala kunye nokuqina kwegesi okwesibini.

Kuxinzelelo oluphakathi, ubukhulu becala inkonzo yolwelo kunye neendlela ezilula, oku kwamkelekile. Njengoko uxinzelelo, i-gas fraction, iqondo lokushisa kunye nokuphambuka kunyuka, "ukulunga ngokwaneleyo" kwicala lokudibanisa liqala ukujonga ngakumbi "njenge-design margin eroded."

Nje ukuba iqula lihambe ngaphaya kwemvulophu yesiqhelo, ayiseyiyo nje yokuphucula imidibaniso yecasing. Iityhubhu inokuba yindlela yokuvuza ebalulekileyo kunye nendawo yokudinwa kwakhona.

Uqhagamshelo olukhethekileyo okanye olukhethekileyo ludla ngokuqwalaselwa xa ezinye zezi zilandelayo ziyinyani:

• Imithombo yerhasi enoxinzelelo oluphezulu apho naluphi na uxinezeleko oluzinzileyo luyinkxalabo enkulu
• I-HP / HT kunye nemithombo yamanzi anzulu kunye nokuqhuma okuphezulu okudityanisiweyo, ukuwa kunye nemithwalo yoxinzelelo
• Ukufikelela okwandisiweyo kunye namaqula atenxe kakhulu ngokugoba okubalulekileyo kunye nobungqongqo be-dogleg
• Ukugcinwa kwegesi, inaliti ye-CO₂ kunye namaqula okulahla kunye nokuhamba ngebhayisikili rhoqo
• Inkonzo emuncu kakhulu, apho ukuqaliswa kokuqhekeka kunye nokukhula kwingcambu yomsonto kufuneka kulawulwe ngokuqinileyo
• Uyilo lweWell olufuna ngokucacileyo ukusebenza koqhagamshelo ukuze lutshatise okanye lugqithise ireyithingi yomzimba wombhobho

Kula maqula, ukuhlala ne-STC/LTC/BTC kunye ne-NUE/EUE ayithethi ngokuzenzekelayo ukuba "ingakhuselekanga" - kodwa ithetha ukuba imvulophu yokusebenza yoqhagamshelo ihlala kufutshane kakhulu nemvulophu yoyilo. Nakuphi na ukwahluka kwitorque, unyango olungaphezulu, ukuziqhelanisa nokwakheka okanye iimeko zokusebenza kunokutyhala inkqubo engxakini.

I-Premium / uxhumano olukhethekileyo luhlala kwi-API 5CT imizimba yombhobho, kodwa iyatshintsha indlela amatywina adibeneyo kunye nokuthwala ngayo umthwalo. Uninzi lwabelana ngeempawu ezimbalwa eziphambili:

Intsimbi ukuya kwintsimbi yokutywina
Endaweni yokuxhomekeka kuphela kwikhompawundi yomsonto, uyilo lweprimiyamu lubandakanya indawo enye okanye ngaphezulu kwentsimbi ukuya kwintsimbi evelisa uxinzelelo oluphezulu kwitorque yokwakheka. Oku kubavumela ukuba bagcine ukusebenza kwegesi phantsi koxinzelelo kunye nokuhamba ngebhayisikile yobushushu.

Igxalaba leTorque
Igxalaba letorque elichaziweyo linika ukumisa okuhle ekupheleni kokwenza. Oko kuphucula ulawulo lwetorque, kunciphisa umngcipheko wokonakala kwetorque engaphezulu, kwaye kwandisa ukugoba kunye nomthamo we-torsional kumaqula atenxileyo kunye ne-ERD.

Ijiyometri yomsonto elungiselelweyo
Iifom zemisonto ezenziwe ngokutsha zinciphisa uxinzelelo kwaye zisasaze umthwalo kuwo wonke umsonto obandakanyekayo. Oko kuphucula ukusebenza kokukhathala apho umtya ubona ukujikeleza, ukugoba kunye nokutshintsha ngokuphindaphindiweyo uxinzelelo.

Iinketho zokugungxula kunye nokugungxula kancinci
Apho ukukhula kwe-OD kubaluleke kakhulu - kufutshane neendawo eziphezulu ze-liner, iindawo zokubopha umva okanye izithintelo eziqinileyo - uqhagamshelwano olugungxulwayo okanye olugungxulwa kancinci lugcina i-OD elawulwayo ngelixa lusabonelela ngamandla kunye nokutywinwa.

Isiqinisekiso esipheleleyo
Uqhagamshelo lwale mihla lweprimiyamu lufanelekile ukusebenzisa i-ISO 13679 / API RP 5C5 okanye iimvavanyo ezifanayo zesikali esipheleleyo, ukugubungela imithwalo edibeneyo, ukukhwela ibhayisekile kwaye, kwiimeko ezininzi, ukugoba. Oko kunika umfanekiso wokwenyani wendlela uqhagamshelo oluziphatha ngayo phantsi kweemvulophu ezifana neendawo, hayi nje iimvavanyo ze-axis enye.

Ezi zibonelelo zibalulekile kuzo zombini i-casing kunye ne-tubing:

• Kwi-casing, kugxilwe kugqibelelo lolwakhiwo kunye nokuqina kwexesha elide legesi.
• Kwityhubhu, wongeza umjikelo wokusebenza, ukuvuselela, ukulawula kakuhle ukusebenza kunye nokutshintsha rhoqo uxinzelelo ngaphezulu.

Nje ukuba uyilo lomthombo lufuna ukudityaniswa kweprimiyamu, umsebenzi awusekho "ukuthenga intambo ekhethekileyo." Idibanisa ezo ziqhagamshelo kuyilo lonke lwe-OCTG kunye nekhonkco le-QA.

Uluhlu lokuhlola lobunjineli olusebenzayo ludla ngokubandakanya:

Chaza imvulophu yokusebenza ngokucacileyo

• Ubuninzi kunye noxinzelelo oluncinci kunye namaqondo okushisa kumtya ngamnye
• Ukuqina okufunekayo kwerhasi kunye noxinzelelo lwecasing oluvunyiweyo oluzinzileyo
• Ubunzima be-dogleg kunye naluphi na ujikelezo olucwangcisiweyo phantsi komthwalo
• Izicwangciso zokusebenza kunye nokuvuselela ezizisa imijikelo eyongezelelweyo

Cacisa iimfuno zesiqinisekiso soqhagamshelwano

• Kufuneka i-ISO 13679 / API RP 5C5 inqanaba lovavanyo (umzekelo, i-CAL IV yenkonzo enzima ye-HP/HT)
• Iimvulophu zomthwalo kufuneka zigqunywe (uxinzelelo oludibeneyo, uxinzelelo, uxinzelelo lwangaphakathi / lwangaphandle, ukugoba ukuba kufanelekile)
• Nayiphi na inkonzo emuncu okanye uvavanyo lomhlwa olufunekayo ngaphaya kweemfuno zemibhobho esisiseko

Ukulungelelanisa umzimba wombhobho kunye nokusebenza koqhagamshelwano

• Qinisekisa ukuba ukuqina, ukugqabhuka kunye nokuwa kokusebenza koqhakamshelwano kuyadibana okanye kudlule ibakala lomzimba wombhobho okhethiweyo kunye nobukhulu bodonga.
• Kuyilo olukwinqanaba eliphezulu, jonga ukuba umdibaniso awubi licandelo elibuthathaka ekuweni

Ukucwangcisa ukuhlolwa, ukwenza kunye namaxwebhu ngaphambili

• Chaza ukulinganisa intambo kunye neenkqubo zokuhlola okubonakalayo kwindawo yokuthunga
• Cacisa iifestile zokwenziwa kwetorque kunye neemfuno zokubeka iliso kuzo zombini iicasing kunye netyhubhu
• Cwangcisa indlela ii-MTCs, idatha yesiqinisekiso soqhagamshelwano, iitshathi zetorque kunye neencwadana ezisebenzayo ziya kufakwa kwincwadi yedatha ye-OCTG kunye neefayile zequla.

Ukunyanga uxhulumaniso lwe-premium njengenxalenye yoyilo - kungekhona emva kokucinga - yinto ethintela iingxabano kamva kwi-rig okanye ngexesha lokuphonononga ulawulo.

Abaqhubi abaninzi sele beyisusile ingxowa yemveliso kwiprimiyamu, uqhagamshelo olungagungqiyo ngegesi, kodwa basaqhuba iityhubhu eqhelekileyo ye-EUE/NUE. Kwimingxuma esemngciphekweni ophezulu, oku kutshintsha ikhonkco elibuthathaka ukusuka kwi-casing ukuya kwi-tubing.

Iimeko apho uqhagamshelo lweprimiyamu yetyhubhu luhlala luthetheleleka lubandakanya:

• Imithombo yerhasi kunye neGOR ephezulu ye-oyile apho imibhobho yokuqina kwexesha elide ibalulekile kunye noxinzelelo lwe-annulus kufuneka ilawulwe ngokuqinileyo.
• Iintambo zetyhubhu kulindeleke ukuba zibone ukuqhekeka okuphindaphindiweyo, ukwenza iasidi, ukucoceka kakuhle kunye nolunye ungenelelo olunzima.
• Ukufikelela okwandisiweyo kunye namaqula athe tye, apho iityhubhu ifumana ukugoba okubalulekileyo, ukungcangcazela kunye nokujikeleza ngexesha lokuqhuba nokuvelisa.
• Iimeko ezimuncu okanye eziphezulu zeCO₂ apho ingcambu yoqhagamshelo iyindawo enokwenzeka yoxinzelelo lwe-corrosion crack

Kula maqula, iityhubhu ezinoqhagamshelo lweprimiyamu - ebonisa igxalaba letorque, itywina lentsimbi kunye nejometri yentambo ephuculweyo - inokunciphisa kakhulu umngcipheko wokuvuza kunye nokungaphumeleli kokudinwa kumalungu, kwaye inike amaqela okusebenza ukuzithemba ngakumbi xa kuqhutywa uxinzelelo lwebhayisikile okanye kuqhutywa ungenelelo olunzima.

Uqhagamshelo olukhethekileyo nolukhethekileyo luzisa elona xabiso likhulu xa luphathwa njengenxalenye ye-API 5CT yecasing epheleleyo kunye nenkqubo yetyhubhu, hayi uphuculo olunye. Oko kuthetha ukuba:

• Ukucwangcisa ngequla okanye ipad: ukuchaza ukuba ngawaphi amaxesha afuna uqhagamshelo lweprimiyamu kwaye yeyiphi enokuhlala ngokukhuselekileyo ngemisonto ye-API.
• Ukugcina iintsapho zonxibelelwano zihambelana ngokusemandleni ngaphakathi komtya okanye kwibala, ukwenza lula iinkqubo, ii-spares kunye noqeqesho lwabasebenzi
• Ukujonga ukuhambelana kwazo zonke izincedisi - iipup joints, crossovers, liner hangers, packers, iivalve zokhuseleko kunye nezinye izixhobo zokugqiba.
• Ukucoca ulungelelwaniso lweyadi ngombala ocacileyo wekhowudi, ukumakisha kunye nezibalo ukuze unxibelelwano olungahambelaniyo lungafikeleli kumgangatho werig.

Iphathwa ngale ndlela, uqhagamshelo lweprimiyamu alulo "igama lemveliso ekhethekileyo" kuluhlu lweentambo, kodwa luyinxalenye ecaciswe ngokucacileyo yesicwangciso sengqibelelo.
