Iindidi ze-Drill pipe kunye ne-Tubular Cutter

Kukho iintlobo ezininzi ezahlukeneyo ze-tubular cutters ezikhoyo kwishishini leoli kunye negesi. Usetyenziso luqhelekile ukuqhawula umbhobho wokubhoboza, iityhubhu yeekhoyili, okanye ukubuyisela umtya wokugqibezela equleni ngokusika umdibaniso we-tubular okanye ukusika ukukhulula indibano yompakisho.

Njengoko kukho konke ukuthunyelwa equleni, kubalulekile ukucwangcisa kwaye ukhethe umsiki ochanekileyo kwisicelo ngasinye kunye nendlela yokuthunyelwa kwayo. Ngokufanelekileyo, yonke imisebenzi yokusika ikhethwa ukuba iqhutywe ngombhobho we-drill okanye umtya wokugqiba kwi-tension, ngokuqhelekileyo ubunzima bomtya kunye ne-10%, apho kunokwenzeka. Umonakalo kwi-casing, okanye emva kwe-tubing, kunokwenzeka ukuba i-cutter engalunganga ikhethiwe. Abanye abasiki abanakho ukusika kwindawo yegesi, ngoko ke inqanaba lolwelo kunye nohlobo lunokuba yinto ekufuneka iqwalaselwe. Ukuba isixhobo sokusika iziqhushumbisi siza kuqhutywa ngokuhambisa itrekta ngocingo, ngoko ke kunokubakho umngcipheko omkhulu wokuba itrektara inokwaphuka okanye ingaphumeleli ekuvuleni isixhobo sokusika. Zonke izixhobo zokusika kufuneka zisetyenziswe ngaphakathi kwiqondo lokushisa elichaziweyo kunye nemida yoxinzelelo.

Iintlobo zeCuter kwiMarike

Iinketho zokusika zingabekwa ngokubanzi kwezi ndidi zilandelayo:

• Iziqhushumbisi Abasiki
• Abasiki be-Electromechanical
• Abasiki beMichiza
• Itotshi yokusika iRadial

UkuqhushumbaCuyathetha:

Izitshizi zeziqhushumbisi zinokwahlulwa ngakumbi kwezi zicelo zilandelayo.

• Isixhobo sokuDiba iKhola yokuNqanda:Ezi zisetyenziselwa ukwahlula imibhobho kwimisebenzi yokubuyisela, kusetyenziswa imirhumo yokudubula ebekwe ngexesha elifanelekileyo ukusika iikhola zokomba kunye nezinye izinto ezinobunzima. Inzame yokusika kufuneka yenziwe ngaphezu kwendawo yokubetha. Umonakalo omkhulu wombhobho kunye nokwahlula kuya kwenzeka ngexesha lenkqubo.
• Imilo yokusika iCharge:Oku kusebenzisa imirhumo eqhumayo ukujolisa ukuqhushumba kwijethi yentsimbi egqobhozayo kwaye isike imathiriyeli ekujoliswe kuyo. Zisetyenziselwa ukuqhawula okuchanekileyo kwimisebenzi ye-downhole. Ukuvutha kwe-tubular kulindeleke ngexesha lokusika kodwa kuye kwaphuculwa ukunciphisa le mpembelelo. Abanye abasiki benzelwe ukwahlula ikhola kwaye bakhulule i-tubular ngale ndlela. Ukuqwalaselwa kuyadingeka xa kuyilwa ukugqitywa ukuqinisekisa ukuba umsiki unokubekwa ngokuchanekileyo kwi-cut to release packer. Ingono yokumisa phezu kompakishi inokunceda kule nkqubo.

Qaphela: Ngelixa abasiki beziqhushumbisi bexhaphakile kwindawo yeoli kunokuba nzima ukubathutha ukuya kwindawo yomthombo ngesaziso esifutshane ngenxa yezithintelo zokhuseleko lwelizwe ngalinye. Abasiki abaqhumayo banokusika ngomtya kwi-tension okanye ucinezelo.

Itotshi yokusika imichiza kunye neRadial:

• Abasiki beMichiza:Oku kusebenzisa imichiza efana ne-bromine trifluoride ukunyibilikisa iintsimbi ngokucocekileyo ngaphandle kobutyobo. Ziluncedo ngakumbi kwiindawo ezibuthathaka okanye ekunzima ukufikelela kuzo, nangona kunjalo kukho izilumkiso ezibalulekileyo zokhuseleko ezifunekayo ukuze ukwazi ukusasaza esi sixhobo ngenxa yeekhemikhali eziyingozi kakhulu kunye neemveliso zazo ezimbini.
• Itotshi yokusika iRadial (RCT):Isebenzisa ijethi yeplasma ukusika imathiriyeli. Esi sixhobo asikho isiqhushumbisi kwaye sinokusasazwa ngokukhawuleza kwihlabathi jikelele ngenxa yezithintelo zezothutho ezimbalwa, nangona kusenokubakho ezinye izinto ezingaphandle koku.
• Ngenxa yesenzo sabo sokusika akukho ukuvutha kwe-tubular. Olu hlobo lwesixhobo lulo lodwa ukhetho lokusika iityhubhu yeekhoyili.

Qaphela: Ngenxa yobume bezi zixhobo kubalulekile ukuba zibekwe embindini ngokuchanekileyo. Zombini ezi zixhobo ziyakwazi ukubambelela eludongeni lwe-tubing ngexesha lokusika. Ivulwe ngokunqwenelekayo ngomtya kuxinzelelo kunye ne-10%.

Abasiki be-Electromechanical:

• Abasiki be-Electromechanical:Aba basiki basebenzisa iintloko ezijikelezayo okanye eziphindaphindayo okanye ii-blades ezisebenza ngombane kwaye zibekwe esweni ukusuka kumphezulu ngexesha lenkqubo yokusika. Ezi ntlobo zezixhobo zilungele imeko-bume apho iziqhushumbisi okanye imichiza ibeka umngcipheko, okanye apho kungenakwenzeka ukuba zihanjiswe kwindawo yomthombo. Ngelixa ababoneleli bezixhobo abaninzi bechaza ukuba izixhobo zabo zinokusika kuzo zombini uxinezeleko kunye noxinzelelo, umtya wokuxinana uya kuhlala ulungile. Apho umtya uxineneyo, kufuneka kuqwalaselwe ukuthintela imiba enebladed izixhobo ezibambekayo ekuqhawukeni kwe-tubular, okanye xa isixhobo sithe shwaka ngexesha lokusikwa esingakwaziyo ukuqalisa ngokutsha ngenxa yothintelo kuyilo lwazo. Ukubuyiswa kwesixhobo kunokuba ngumngeni xa isiphaluka esifutshane sombane sisenzeka ngexesha lokusika. Njengabasiki abaninzi, ukubekwa kwindawo echanekileyo kubalulekile kwimpumelelo.

Qaphela: Enye inzuzo enkulu yabasiki be-electromechanical ngaphezu kwezinye iindlela zokusika kukukwazi ukugqiba ukusikwa okuphindaphindiweyo ngexesha elinye elihloniphekileyo kwiqula.

AmandlaI-Non-explosive Downhole Cutter

• I-Non-explosive Downhole Cutter inesixhobo se-ankile kunye a
• Isixhobo sokumisa i-anchoring isixhobo sokusika kwindonga yangaphakathi yombhobho ukuba inqunywe, ukukhusela isixhobo ukuba sihambe ngexesha lokusika; i-combustor ivelisa i-high-high-high-high-high-high-high-pressure-high-pressure metal metal metal fluid ehlanjululwayo kwaye ikhuphe umbhobho, ngaloo ndlela ifezekisa injongo yokusika.
• Ukhetho lokhuseleko luqwalaselwa, xa isixhobo singenako ukukhutshwa ngexesha lomsebenzi, ngokufaka igalelo le-230mA yangoku okanye ukuphakamisa ucingo olungaphezu kwe-1.6T amandla okucheba izikhonkwane zokucheba kunye nokukhulula umtya wesixhobo.

Oku kulandelayo yimeko yovavanyo lommandla olwenziwa liqela leenjineli zeVigor kwindawo ye-oyile eTshayina ngereferensi:

Ukuvalwa kokhuseleko lomthwalo ogqithisiweyo wangoku, ikhadi lempompo esezantsi, ukusika kwangaphambili kwe-2-3/8 "i-tubing, ukusika ubunzulu obuyi-825.55m. I-Φ43 Wireline Non-explosive Downhole Cutter yayisetyenziselwa ukwakhiwa, kwaye ubunzima bokunqunyanyiswa buphakanyiswe yi-8t, kwaye ukusika kwagqitywa. igqitywe ngempumelelo kwi-804.56m, kwaye ixesha lokusika lilonke lalimalunga ne-6min. I-incision icocekile, akukho flanging, akukho bubanzi bokwandisa.

Ukuza kuthi ga ngoku, i-On-explosive Downhole Cutter esuka kwi-Vigor iye yaba yenye yezona zixhobo ezidumileyo zokusika umbhobho we-downhole, isixhobo siye saqatshelwa kakhulu ngabasebenzisi bokugqibela ngenxa yokuthembeka kwayo okuphezulu, ukuba unomdla kwi-Downhole Cutter ye-Vigor's Non-explosive Downhole Cutter. , nceda ungalibazisi ukunxibelelana nathi.
