Izicelo zekhava kawoyela:

Okusetshenziselwa ukubhoboza imithombo kawoyela kusetshenziswa kakhulu enqubweni yokubhoboza kanye nangemva kokuqedwa kokusekelwa kodonga lomthombo, ukuqinisekisa inqubo yokubhoboza kanye nokusebenza okuvamile komthombo wonke ngemva kokuqedwa. Ngenxa yezimo ezahlukene zejiyoloji, isimo sokucindezeleka ngaphansi komhlaba siyinkimbinkimbi, futhi isenzo esiphelele sokucindezeleka okuqinile, okucindezelayo, okugobayo kanye nokugoba emzimbeni wepayipi kubeka phambili izidingo eziphakeme zekhwalithi yebhokisi ngokwalo. Uma ibhokisi ngokwalo lonakele ngenxa yesizathu esithile, kungase kuholele ekunciphiseni ukukhiqizwa komthombo wonke, noma ngisho nokulahlwa.

Izinhlobo zebhokisi lamafutha:

Ngokusho kwe-SY/T6194-96 “i-petroleum casing”, ingahlukaniswa ngezinhlobo ezimbili: i-casing emfushane enezintambo kanye nekhola yayo kanye ne-casing ende enezintambo kanye nekhola yayo.

Izinga lokufakwa kwamafutha kanye nokupakisha:

Ngokusho kwe-SY/T6194-96, i-casing yasekhaya kufanele iboshwe ngocingo lwensimbi noma ngebhande lensimbi. Ingxenye eveziwe ye-casing ngayinye kanye nentambo yekhola kufanele iboshwe ngendandatho evikelayo ukuze kuvikelwe intambo.

Ibhokisi kufanele linikezwe intambo kanye nekhola ngokuya nge-API SPEC 5CT1988 uhlelo lokuqala noma kunoma yiziphi izinhlobo zokuphela kwepayipi ezilandelayo: isiphetho esiyisicaba, intambo eyindilinga engenakhola noma ikhola, intambo ye-trapezoidal engaphandle enekhola noma engenayo, intambo eqondile, ukucutshungulwa kwesiphetho okukhethekile, ukwakhiwa kwendandatho yokuvala.

Izinga lensimbi lebhokisi likaphethiloli:

Ibanga lensimbi yekheyiji kawoyela lingahlukaniswa ngamabanga ensimbi ahlukene ngokuya ngamandla ensimbi uqobo, okungukuthi i-H-40, i-J-55, i-K-55, i-N-80, i-C-75, i-L-80, i-C-90, i-C-95, i-P-110, i-Q-125, njll.Izimo zemithombo ezahlukene, ukujula komthombo, ukusetshenziswa kwebanga lensimbi nakho kuhlukile. Ibhokisi ngokwalo liyadingeka futhi ukuthi limelane nokugqwala ezindaweni ezigqwalayo. Ezindaweni ezinezimo zejiyoloji eziyinkimbinkimbi, ibhokisi liyadingeka futhi ukuthi limelane nokuchotshozwa.

Ifomula yokubala isisindo sebhokisi likawoyela imi kanje:

KG/ m = (ububanzi bangaphandle – ubukhulu bodonga) * ubukhulu bodonga *0.02466

Ubude bebhokisi likawoyela:

Kunezinhlobo ezintathu zobude ezichazwe yi-API: R-1 4.88 kuya ku-7.62m, R-2 7.62 kuya ku-10.36m, R-3 10.36m kuya kubude obude.

Uhlobo lwebhakede lekhava likaphethiloli:

I-API 5CTIzinhlobo zama-buckle e-casing petroleum zifaka phakathi i-STC (i-buckle ende eyindilinga), i-LTC (i-buckle ende eyindilinga), i-BTC (i-buckle ye-ladder engaphelele), i-VAM (i-king buckle) kanye nezinye izinhlobo zama-buckle.

Ukuhlolwa kokusebenza ngokomzimba kwebhokisi likaphethiloli:

(1) Ngokusho kwe-SY/T6194-96. Ukwenza isivivinyo sokuthamba (GB246-97) (GB228-87) kanye nesivivinyo se-hydrostatic.

(2) ukuhlolwa kwe-hydrostatic, ukuhlolwa kokuthamba, ukuhlolwa kokuqhekeka kokugqwala kokucindezeleka kwe-sulfide, ukuhlolwa kokuqina (inguqulo yakamuva ye-ASTME18 noma i-E10), ukuhlolwa kokuthamba, ukuhlolwa komthelela ophambene (ASTMA370, ASTME23 kanye nenguqulo yakamuva yezindinganiso ezifanele) ngokwemibandela ye-American Petroleum Institute APISPEC5CT1988 uhlelo lokuqala Ok), ukunqunywa kosayizi wezinhlamvu (inguqulo yakamuva ye-ASTME112 noma enye indlela)

Ukungenisa nokuthumela ngaphandle kwekhava kawoyela:

(1) Amazwe ayinhloko okungenisa uwoyela yilawa: iJalimane, iJapan, iRomania, iCzech Republic, i-Italy, i-United Kingdom, i-Austria, iSwitzerland, i-United States, i-Argentina, iSingapore nayo engenisa.Izindinganiso zokungenisa zibhekisela ku-American Petroleum Institute standard API5A, 5AX, 5AC. Izinga lensimbi yi-H-40, J-55, N-80, P-110, C-75, C-95 njalo njalo. Imininingwane eyinhloko yi-139.77.72R-2, 177.89.19R-2, 244.58.94R-2, 244.510.03R-2, 244.511.05r-2, njll.

(2) Kunezinhlobo ezintathu zobude ezichazwe yi-API: u-R-1 ungu-4.88 ~ 7.62m, u-R-2 ungu-7.62 ~ 10.36m, u-R-3 ungu-10.36m kuya kubude obude.

(3) Ingxenye yezimpahla ezingenisiwe imakwe nge-LTC, okungukuthi, umkhono we-filament buckle.

(4) Ngaphezu kwezindinganiso ze-API, inani elincane lama-bushing angeniswa eJapan ahambisana nezindinganiso zabakhiqizi baseJapan (njengeNippon Steel, Sumitomo, Kawasaki, njll.), izinombolo zensimbi yi-NC-55E, NC-80E, NC-L80, NC-80HE, njll.

(5) Ezimweni zezimangalo, kube neziphambeko zokubonakala njengebhakede elimnyama, umonakalo wethayi yocingo, ukugoqwa komzimba wepayipi, ibanga eliqinile lebhakede eliphukile kanye nentambo ngaphandle kokubekezelelana, ukuhlanganisa inani lika-J ngaphandle kokubekezelelana, kanye nezinkinga zekhwalithi yangaphakathi njengokuqhekeka okuqhekekayo kanye namandla aphansi e-casing.

Izakhiwo zemishini zesigaba ngasinye sensimbi yebhokisi likaphethiloli:
