Imibhobho ye-OCTGzisetyenziselwa ikakhulu ukuqhuba ioyile yeoyile kunye negesi kunye nokuhambisa ioyile kunye negesi. Ibandakanya imibhobho yeoyile, i-oyile yeoyile, kunye nemibhobho yokukhupha ioyile.Imibhobho ye-OCTGIsetyenziselwa ikakhulu ukudibanisa ii-Drill Collars kunye ne-Drill Bits kwaye idlulisela amandla okuqhuba.I-Petroleum Chears isetyenziselwa ukuxhasa iqula ngexesha lokuqhuba kwaye emva kokugqitywa, ukuqinisekisa ukusebenza kweoyile epheleleyo ngexesha lenkqubo yokuqhuba kunye nokugqitywa. Ioyile kunye negesi emazantsi e-oyile kakuhle zithuthwa ngumphezulu kwityhubhu ye-oyile.
Ukushenxisa kweoyile kukuphila ngokwenza ixesha lokugcina ukusebenza kweequla leoyile. Ngenxa yeemeko ezahlukeneyo zejografi, uxinzelelo lwemeko ephantsi komhlaba luntsonkothile, kwaye iziphumo ezidityanisiweyo zengxwabangxwaba, ukucinezelwa, ukugoba, kunye noxinzelelo lokuthambisa umzimba kwimigangatho ephezulu. Nje ukuba isikhephe ngokwayo siyonakalisile isizathu esithile, inokukhokelela ekunciphiseni kwemveliso okanye ukufuduka kakuhle.
Ngokwamandla entsimbi ngokwayo, i-Cheng inokwahlulwa yangamabanga ahlukeneyo ensimbi, eyi-J55, K50, i-Q85, i-Q90, i-Q90, i-Q90, i-v150, i-v150, i-v150, i-v150, i-v150, i-v150, i-v150, i-v150, njl. Kwimeko zoncedo, kuyacelwa ukuba isikhephe ngokwaso sinokungaxhathisi. Kwimimandla enemigangatho yejografini yejografi, kuyafuneka ukuba i-cheng i-anting ngayo iwa.

Ⅱ. Umbhobho weoyile
1. Ukuhlelwa kwemibhobho yeoyile
Imibhobho yeoyile yahlulahlulwe yangamatyhubhu (i-nu) yetyhubhu, iphazamisekile yangaphandle (i-EU), kunye ne-tubing edibeneyo. Ityhubhu engakhathali ibhekisa kumbhobho wokuphela kwento enikiweyo ngaphandle kokuthambisa kwaye ixhotywe ngokudibana. Ityhubhu yangaphandle iphekisiyo ibhekisa kwimibhobho emibini eyenziwe ngaphandle, emva koko ixutywe kwaye ifakwe ngamaqhinga. Ityhudiyo edityanisiweyo edibeneyo ibhekisa kumbhobho oxhunyiwe ngokuthe ngqo ngaphandle kokudibana, kunye nesiphelo esinye esixhonywe kwintambo yangaphandle engaphandle kunye nesinye isiphelo sangaphakathi esikhutshiweyo.
2. Indima yetyhubhu
①, Ukukhutshwa kweoyile kunye negesi: Emva kokuba i-oyile kunye ne-qulls ye-oyile iyakhutshiwe kwaye ifakwe idijithali kwi-oyile yokukhuphela i-oyile kunye negesi emhlabeni.
②, Inaliti yamanzi: Xa uxinzelelo lwe-Dohole alonelanga, lubambe amanzi equleni ngetyhubhu.
③, Inaliti yeSteam: Kwinkqubo yokufumana kwakhona i-oyile ye-termal yeoyile, i-Steam kukufaka kwiqula leoyile.
.
Inqanaba le-3.Steel yenqanaba lombhobho yeoyile
Ibango lentsimbi yombhobho weoyile yile: H40, J55, N80, L80, C90, T95, P910.
I-N80 yahlulahlulwe yangu-N80-1 kunye ne-N80Q, bobabini bengabalinganisi abalinganiyo, kwaye bahlukane nemeko yokuhambisa i-AR3, kwaye banokuyiswa ngendlela yokuhambisa i-AR3, kwaye banokuyiswa ngokuqinileyo kwi-ARTALS, impembelelo kunye novavanyo olungagungqiyo aludingeki; I-N80Q kufuneka ivuthwele (ukucima kunye nokuhamba komsindo) Unyango, umsebenzi wempembelelo kufuneka uhambelane nezibonelelo ze-API 5, kwaye kufanele ukuba kungavavanywa kakhulu.

Ⅲ. Ukuthambisa
I-1, ihrinta i-rinta kunye nendima yokucoca
Ukushenxisa ngumbhobho wentsimbi oxhasa udonga lwequla leoyile negesi. Iingqimba ezininzi ze-chengi zisetyenziswa kwi-it nganye ngokweenzulu ezinzulu zokuntywila kunye neemeko zejografi. Isamente isetyenziselwa ukuthambisa i-cheng emva kokuba ithotyelwe equleni, kwaye ngokungafaniyo nombhobho weoyile kunye nombhobho we-Drill, ayinakusetyenziswa izixhobo ezinokuchitheka. Ke ngoko, ukusetyenziswa kweeakhawunti ze-csher ngaphezulu kwe-70% yazo zonke ioyile. Ukushenxiswa kunokubekwa uluhlu:
2.Conuct Chengi
ikakhulu isetyenziselwa ukuqhuba elwandle kunye nenkqantosi ukuya phambili kumanzi olwandle kunye nentlabathi yokuqinisekisa inkqubela phambili yokuqhuba, i-φ76mm (i-30mm, φ76mm (i-30mm.
Ukushenxisa komphezulu: Isetyenziselwa ukuqhuba okokuqala, ukuqhuba kuvula umphezulu we-strata evulekileyo, ukuze itywine le nxalenye ye-strata ukuba itywinwe, kufuneka itywinwe nge-cuding. Owona mgaqo uphambili we-Chengqam engaphezulu: 508mm (206mm), i-406MM (i-339mm (i-20-3 / i-4-3mm (i-20-3 / 9in), njl. Ubunzulu bombhobho ophantsi buxhomekeke kubunzulu bespotimu evulekileyo, ebukhulu be-80 ~ 1500 m. Uxinzelelo lwayo lwangaphandle nangaphandle aluphambi, kwaye ngokubanzi uyamkela ibanga le-K55 yenqanaba le-K80 okanye i-N80 ibakala.
3.Ukuhlala
Ukukhuphela ngobuchwephesha kusetyenziswa kwinkqubo yokuqhuba yendlela enobunzima. Xa udibana neendawo ezintsokothileyo ezinje ngomaleko, umaleko we-oyile, umaleko wegesi, ungqimba lwamanzi, ukuvuselelwa kwe-ityuwa, ityuwa yetyuwa. Amanye amaqula anzulu kwaye entsokothile, kwaye ubunzulu bequla lufikelela kumawakawaka eemitha, olu hlobo lwequla elininzi luphakame kakhulu, ukusetyenziswa kwe-P10, ukusebenzisa amabakala e-PAEL kuqhekezile kwi-Q125 okanye inqaku eliphezulu le-API, njenge-V150. Owona mgaqo uphambili we-Chente yobugcisa yile: 339.73 Eyona ngcaciso iphambili ye-Chente yobugcisa yile ilandelayo: 339.7mm (i-22-3 / 80mm (i-7-5 / i-7-5mm (i-7-5mm (i-7,8mm (i-7in) njalo njalo.
I-4. I-OB WOKUKHUSELEKA
Xa iqula lenziwe kwindawo yokuya efikelela kuyo (umlinganiso oqukethe ioyile kunye negesi), kuyimfuneko ukusebenzisa i-calical yeoyile yokutywina ioyile kunye negesi ye-oyile yi-oyile ye-oyile. Ukucingisisa kweoyile kuzo zonke iintlobo zokucingela elona xesha linzulu, iipropathi zalo zoomatshini kunye neemfuno zentsebenzo ze-k55, v10, v10, v150, v150, v150, v150, v150, v150, v150, v150, v150, v150, v150, v150, v150, v150, v150, v150, v150, v150, v150, v150, v150, v150, v150, v150, v150, v150, v150, v150, v150, v150, v150, v150, v150, v150, v150. Ezona ngcaciso ziphambili ze-cheng cheng zezi: 177.8mm (7in), i-16-5mm (i-6-5m), i-12,5mm (i-5,3mm (i-5,3mm (kunye nentsebenzo yentsebenzo yendlela yokutywina iphezulu.
V.drill pipe
1, Ukwahlulahlulwa kunye nendima yombhobho wezixhobo zokuqhuba
Umbhobho we-Square Pill, umbhobho we-Drill, umbhobho wokuntywila kunye nokuntywila kwikhola kwi-Drill Izixhobo zenza umbhobho weglasi. Umbhobho we-Drill sisixhobo esinxilisayo esihamba ngesantya esikhuphayo esiphuma kumhlaba ukuya ezantsi kwequla, kwaye ikwayijelo elivela emhlabeni ukuya ezantsi kwequla. Inendima emithathu ephambili: ② Ukuxhomekeka kubunzima bayo ukuze uxinezeleke kwi-Drill bit ukuze uwaphule iliwa ezantsi equleni; ③ Ukudlulisela i-fluid ye-fluid, oko kukuthi, ukuntywila kodaka ngokusebenzisa i-pumpmu yoxinzelelo ephezulu, kwaye ukhule i-roun furting ye-rock, kwaye uqhubeke nequla lokuqhuba kakuhle. I-Drill Pipe kwinkqubo yokuqhuba ukuze ikwazi ukwahlukana nemithwalo entsokothileyo entsokothileyo, enjenge-tedin, uxinzelelo, ukuthambisa, umphezulu wangaphakathi nayo ixhomekeke ekuphuculeni kwaye kulungelelwaniso.

I-psl1 ayifuni uvavanyo olungenantlonelo, i-psl2 kufuneka libe lisebe lovavanyo olungelolize.
Vi.prerium uqhagamshelo
1, Intshayelelo yoqhagamshelo lwePremiyamu
I-buckle ekhethekileyo yahlukile kwintambo ye-API ngesakhiwo esikhethekileyo somtya wepayi. Nangona i-API ye-API ye-API isetyenziswa ngokubanzi kwi-oyile, iintsilelo zayo ziboniswe ngokucacileyo kwindawo ekhethekileyo ye-oyile, nangona i-API ilingana ne-8% yamandla e-Proread, ngenxa yoko ayinakusetyenziswa ekuxhaphazweni kwemithombo enzulu; Ikholamu ye-API ikhutshiwe kwikholamu ye-Prapezoidal ye-Trapezoidal ye-Trapezoidal ye-pile, intsebenzo ye-ntensle yenxalenye enesitayile ilingana namandla omzimba, ngenxa yoko ayinakusetyenziswa kwimithombo enzulu; I-API ingqayi yekhonkco le-trapezoidal ikhutshiwe, intsebenzo yayo yenja ayilunganga. Nangona intsebenzo ye-quinser yekholamu iphakamile kakhulu kune-API uqhagamshelo lwe-API ngokujikeleza, ukusebenza kwalo kulunge kakhulu, ke ayinakusetyenziswa ekuxhaphazeni imithombo yegesi yegesi ephezulu; Ukongeza, igrisi ethambileyo inokudlala indima yayo kwindalo esingqongileyo kunye neqondo lokushisa elingaphantsi kwe-95 ℃, ukuze ingasetyenziswa ekuxhaphazeni i-upols yobushushu obuphezulu.
Xa kuthelekiswa nentambo ye-API kunye noQhagamshelo lweTraupoidal yeTraupoidal, Unxibelelwano lwePremiyamu lwenze inkqubela phambili kule miba ilandelayo:
.
.
(3) kukhetho lwezinto ezibonakalayo kunye nokuphuculwa kwenkqubo yonyango, ngokusisiseko kwasombulula ingxaki yentambo enamathela ngasemva
.
.
Okwangoku, umhlaba uphumeze ngaphezu kwe-100 iintlobo zonxibelelwano lweprimiyamu kunye netekhnoloji ye-patered.
Ixesha leposi: NgoFebwe-21 ukuya ku-2424
