Ipayipi lokubhoboza elihlangene liyingxenye yepayipi lokubhoboza, elihlukaniswe ngamajoyinti wesilisa namalunga wesifazane, axhunywe kuzo zombili iziphetho zomzimba wepayipi lokubhoboza. Isixhumi sihlinzekwa ngentambo yesikulufu sentambo (intambo yesikulufu esiwugqinsi) ukuxhuma ipayipi ngalinye lokubhoboza. Enqubweni yokubhoboza, ilunga livame ukuhlakazwa, futhi indawo ehlangene ibhekana namandla amakhulu okuluma, ngakho-ke ubukhulu bodonga obuhlangene bepayipi lokubhobo bukhulu, ububanzi obuhlangene obungaphandle bukhulu kunobubanzi obungaphandle bomzimba wepayipi, kanye nensimbi ye-alloy. ngamandla aphezulu kusetshenziswa. Izihlanganisi zamapayipi okubhoboza asekhaya ngokuvamile enziwa ngensimbi eyingxubevange engu-35CrMo.
Ukuxhumana kwentambo yesikulufu kumele kugcwaliswe ngezimo ezintathu, okungukuthi, ubukhulu bulingana, uhlobo lwentambo yesikulufa luyafana, futhi intambo yesikulufa yesilisa neyesifazane ifaniswe. Ubukhulu obuhlangene bepayipi lokubhoboza elihlukene buhlukile. Uhlobo lwentambo yepayipi yokubhoboza yesayizi efanayo nayo ihlukile. Uhlobo oluhlangene olusetshenziswa umkhiqizi wepayipi lokubhoboza ngamunye nalo kunzima ukuhambisana ngokuphelele. Ngakho-ke, ukuze kube lula ukuhlukanisa phakathi kwezihlanganisi zamapayipi okubhoboza kanye nezicelo zobunjiniyela, i-API yenze izinhlinzeko ezifanayo ngohlobo lwamapayipi okubhoboza amapayipi, okwenza amapayipi okubhoboza e-API avame ukusetshenziswa embonini ye-petroleum.
Ukufakwa kwepayipi le-API kuyatholakala kuwo womabili amazinga amadala namasha. Ipayipi elidala lokubhoboza ipayipi le-API lihlongozwa ukuthi lisetshenziswe kusenesikhathi ipayipi lokubhola elihle, elihlukaniswe ngezinhlobo ezintathu: ifulethi langaphakathi (IF), elinezimbobo (FH) kanye nejwayelekile (REG).
Ilunga elingaphakathi eliyisicaba lisetshenziselwa ikakhulukazi ukujiya kwangaphandle kwepayipi lokubhoboza, elibonakala ngobubanzi bangaphakathi bepayipi lokubhoboza kanye nobubanzi bangaphakathi belunga lapho ukuqina komzimba wepayipi, futhi ukumelana nokugeleza koketshezi lokubhoboza kuncane. , okulungele ukuthuthukisa amandla wamanzi we-drill bit, kodwa ububanzi bangaphandle bokuhlanganyela bukhulu futhi kulula ukugqoka.
Ijoyinti enezimbobo ifanele ukujiya kwangaphakathi kwepayipi lokubhoboza, elibonakala ngama-diamediamets amabili angaphakathi epayipi lokubhoboza, kanti ububanzi bangaphakathi bokuhlangana bulingana nobubanzi bangaphakathi bokujiya bomzimba wepayipi, kodwa ngaphansi ububanzi bangaphakathi bengxenye yomzimba wepayipi. Ukumelana noketshezi lokubhoboza olugeleza ngokuhlanganyela kukhulu kunelunga elingaphakathi eliyisicaba, kodwa ububanzi balo bangaphandle buncane kunalolo lwelunga elingaphakathi eliyisicaba.
Ukuhlanganiswa okujwayelekile kulungele ukuqina kwangaphakathi kwepayipi lokubhoboza. I-diameter yangaphakathi yaleli lungu lincane kakhulu, lingaphansi kobubanzi bangaphakathi bokuqina kwepayipi lokubhoboza. Ngakho-ke, kunama-diameter amathathu ahlukene okubhoboza amapayipi axhumene namalunga ajwayelekile. Uketshezi lokumba lugeleza kuleli lunga elinokumelana okukhulu kakhulu, kodwa linobubanzi obuncane obungaphandle kanye namandla amakhulu. Amajoyinti avamile avame ukusetshenziselwa ipayipi lokubhoboza elinobubanzi obuncane kanye nepayipi lokubhola elihlehlayo, kanye nokubhoboza, amathuluzi okudoba, njll. Izinhlobo ezintathu zamalunga zonke zisebenzisa imicu yomumo othi "V", kodwa uhlobo lwentambo yesikulufu (evezwa ububanzi ukusika okuphezulu), ibanga lentambo yesikulufa, i-taper nosayizi kuhluke kakhulu.
Ukuhlonza okuhlangene
I-1.hole FH, XH, ayijwayelekile esitolo samathuluzi, ayisetshenziswa kakhulu.
2.esetshenziswa ngokujwayelekile i-IF kanye ne-REG evamile, umehluko umi kanje:
UMA izinkinobho ezi-4 iyintshi ngayinye, intambo yesikulufu esihlobene iba mkhulu, futhi i-taper incane, izinkinobho ezingu-REG 5 iyintshi ngayinye, intambo yesikulufu esihlobene incane, futhi i-taper inkulu. Usayizi wentambo yesikulufu se-IF isukela ku-2-3/8 "kuya ku-4-1/2", futhi lezo ezinkulu kuno-4-1/2 "azinayo i-IF, ngokuvamile i-REG, lapho 7-5/8" nangaphezulu zine akukho REG.
3. Indlela evamile yokukhuluma:
Imelwe izinombolo ezintathu, njenge-310,410,411, njll.
Inombolo yokuqala ikhombisa usayizi (2 ~ 7) ngokuvamile: 2-2 -, 3-3-7/8 ", 1/2", 4-4-1/2 ", 5 1/2 "- 5 -, 6 -6-5/8", Julayi 7-5/8 ";
Inombolo yesibili ikhombisa uhlobo lwentambo yesikulufu (kukhona 1, 2, 3), 1-- IF; 2---FH; 3-- REG;
Inombolo yesithathu imele owesilisa nowesifazane (imelwe ngu-0 no-1)
0--Ibhokisi( owesifazane); 1--Iphini (owesilisa);
4.ezinye izinhlobo zentambo ye-screw pipe yokubhoboza evamile yi-BTC, MT, AMT, HT55 njalonjalo.
5.ngaphezu kwalokho, uhlobo lwentambo yesikulufu evamile yemoto engu-7-5/8 "REG, 6-5/8" REG, 4-1/2 "REG, nayo ine-4-1/2" IF. Uhlobo lwentambo yesikulufu evamile ye-scraper yepayipi kanye ne-hydraulic cutter yi-REG.
