Izinhlobo ze-Drill pipe kanye ne-Tubular Cutter

Kunezinhlobo eziningi ezahlukene zabasiki be-tubular ezitholakala embonini kawoyela negesi. Izicelo zivame ukusika ipayipi lokubhoboza, ishubhu ikhoyili, noma ukubuyisa intambo yokuphothula emthonjeni ngokusika ijoyinti leshubhu noma ukusikwa ukuze kukhishwe ukuhlanganiswa kompakishi.

Njengakho konke ukuthunyelwa emthonjeni, kubalulekile ukuhlela nokukhetha isisiki esilungile sohlelo ngalunye kanye nendlela yaso yokusatshalaliswa. Ngokufanelekile, yonke imisebenzi yokusika ikhethwa ukuba yenziwe ngepayipi lokubhoboza noma intambo yokuqedela ngokushuba, ngokuvamile isisindo sentambo kanye no-10%, lapho kungenzeka khona. Ukulimala kwe-casing, noma ngemuva kweshubhu, kungenzeka uma kukhethwe umsiki ongalungile. Abanye abasiki abakwazi ukusika endaweni yegesi, ngakho izinga loketshezi kanye nohlobo kungase kube isici okufanele icatshangelwe. Uma i-explosive cutter izosetshenziswa ngokudluliswa kwe-wireline tractor, khona-ke kungase kube nengozi enkulu yokuthi ugandaganda ungahlukana noma wehluleke ekuvuleni umsiki. Wonke amathuluzi okusika kufanele asetshenziswe ngaphakathi kwemingcele yawo yokushisa nengcindezi ebekiwe.

Izinhlobo Zomsiki Emakethe

Izinketho zokusika zingafakwa ngokubanzi ezigabeni ezilandelayo:

• Iziqhumane Abasiki
• Abasiki be-Electromechanical
• Ama-Chemical Cutters
• I-Radial Cutting Torch

IziqhumaneCuthi:

Izicucu zeziqhumane zingahlukaniswa zibe izinhlelo zokusebenza ezilandelayo.

• Ithuluzi Le-Drill Collar Severing Colliding:Lezi zisetshenziselwa ukunqamula amapayipi emisebenzini yokutakula, kusetshenziswa amanani okuqhuma anesikhathi esinembile ukusika amakholola okubhoboza nezinye izinto ezisindayo. Umzamo wokusika kufanele wenziwe ngaphezu kwephuzu lokushaya. Umonakalo omkhulu wamapayipi nokuhlukaniswa kuzokwenzeka phakathi nenqubo.
• Ama-Shape Charge Cutters:Lezi zisebenzisa iziqhumane ukuze zigxilise ukuqhuma kundiza yensimbi engena futhi isike into eqondiwe. Zisetshenziselwa ukuhlukaniswa okuqondile ekusebenzeni kwe-downhole. Ukuvutha kwe-tubular kulindeleke ngesikhathi sokusika kodwa kuye kwathuthukiswa ukuze kuncishiswe lo mphumela. Abanye abasiki benzelwe ukuhlukanisa ikhola futhi bakhulule i-tubular ngale ndlela. Ukucatshangelwa kuyadingeka lapho uklama ukuqedwa ukuze uqinisekise ukuthi isisiki singabekwa ngokunembile ukuze kusikelwe ukukhulula ipaki. Ingono ehlala phezu kompakishi ingasiza kule nqubo.

Qaphela: Nakuba abasiki beziqhumane bevamile endaweni kawoyela kungase kube nzima ukuthutha baye endaweni yomthombo ngesaziso esifushane ngenxa yemikhawulo yezokuphepha yezwe ngalinye. Abasiki abaqhumayo bangakwazi ukusika ngentambo ngokucindezela noma ukuminyanisa.

Ikhemikhali ne-Radial Cutting Torch:

• Ama-Chemical Cutters:Laba basebenzisa amakhemikhali afana ne-bromine trifluoride ukuncibilikisa izinsimbi ngokuhlanzekile ngaphandle kwemfucumfucu. Ziwusizo ikakhulukazi ezindaweni ezizwelayo noma okunzima ukufinyelela kuzo, nokho kunezinyathelo zokuphepha ezibalulekile ezidingekayo ukuze ukwazi ukusebenzisa lesi sisetshenziswa ngenxa yamakhemikhali ayingozi kakhulu kanye nemikhiqizo emibili.
• I-Radial Cutting Torch (RCT):Isebenzisa ijethi ye-plasma ukusika izinto. Leli thuluzi alinaziqhumane futhi lingatshalwa ngokushesha emhlabeni wonke ngenxa yemikhawulo embalwa yezokuthutha, nakuba kungase kube khona okuhlukile kulokhu.
• Ngenxa yesenzo sabo sokusika akukho ukuvutha kwe-tubular. Lolu hlobo lwamathuluzi ngokuvamile luwukuphela kwenketho yokusika amashubhu ekhoyili.

Qaphela: Ngenxa yemvelo yala mathuluzi kubalulekile ukuthi abekwe endaweni eyodwa ngendlela efanele. Womabili la mathuluzi angakwazi ukunamathela odongeni lwamashubhu ngesikhathi sokusika. Kwenziwe kwasebenza kahle ngeyunithi yezinhlamvu ekucindezelekeni kanye no-10%.

Ama-Electromechanical Cutters:

• Ama-Electromechanical Cutters:Laba basiki basebenzisa amakhanda okusika ajikelezayo noma aphindaphindayo anikwa amandla kagesi futhi aqashwe phezulu phakathi nenqubo yokusika. Lezi zinhlobo zamathuluzi zilungele izindawo lapho iziqhumane noma amakhemikhali ebeka engcupheni, noma lapho ngokomthetho kungenakwenzeka ukuwahambisa endaweni yomthombo. Nakuba abahlinzeki bamathuluzi abaningi bethi amathuluzi abo angakwazi ukusika kukho kokubili ukungezwani nokuminyanisa, intambo ekucindezelekeni izohlala ilungile. Lapho iyunithi yezinhlamvu icindezelekile, ukucatshangelwa kuyadingeka ukuze kugwenywe izinkinga ngamathuluzi anezinsimbi abambeke ekubhodlweni kwe-tubular, noma lapho ithuluzi libambelela ngesikhathi sokusika elingakwazi ukuqala kabusha ngenxa yemikhawulo eklanyweni yalo. Ukuthola ithuluzi kungaba yinselele uma isifunda esifushane sikagesi senzeka ngesikhathi sokusika. Njengabasiki abaningi, ukufakwa endaweni eyodwa okunembile kubalulekile ukuze uphumelele.

Qaphela: Inzuzo eyodwa enkulu yabasiki be-electromechanical ngaphezu kwezinye izindlela zokusika amandla okuqeda ukusikeka okuningi ngesikhathi esisodwa esihloniphekile emthonjeni.

AmandlaI-Downhole Cutter engaqhumi

• I-Downhole Cutter engaqhumi iqukethe idivayisi okusetshenzwa kulengwa kuyo kanye a
• Idivaysi yokunamathisela ihange ithuluzi lokusika odongeni lwangaphakathi lombhobho ukuze linqunywe, livimbele ithuluzi ukuthi lingahambi ngesikhathi sokusika; i-combustor ikhiqiza uketshezi lwensimbi oluncibilikisiwe olunokushisa okuphezulu nokucindezela okuphezulu olukhuhla futhi lushise ipayipi, ngaleyo ndlela lufeze injongo yokusika.
• Inketho yokuphepha iyacatshangelwa, lapho ithuluzi lingakwazi ukunqanyulwa phakathi nomsebenzi, ngokokufaka kwe-230mA yamanje noma phakamisa intambo yocingo ngaphezu kwamandla angu-1.6T ukuze ugunda izikhonkwane zokugunda futhi ukhulule iyunithi yezinhlamvu zamathuluzi.

Okulandelayo yicala lokuhlola inkambu elenziwa ithimba lonjiniyela be-Vigor endaweni yesizinda sikawoyela e-China ukuze kubhekwe:

Ukuvalwa kwamanje kokuvikela ukulayisha ngokweqile, ikhadi lepompo lembobo ephansi, ishubhu elisikwe ngaphambili elingu-2-3/8", ukujula kokusika okungu-825.55m. I-Φ43 Wireline Non-explosive Downhole Cutter yasetshenziselwa ukwakha, futhi isisindo sokulengiswa saphakanyiswa ngo-8t, futhi ukusika kwasetshenziswa. kuqedwe ngempumelelo ku-804.56m, futhi isikhathi sokusika esiphelele sasimayelana ne-6min.I-incision ihlanzekile, ayikho i-flanging, akukho ububanzi bokunweba.

Kuze kube manje, I-Downhole Cutter Engaqhumi evela ku-Vigor isibe enye yamathuluzi okusika amapayipi okubhoboza adume kakhulu, leli thuluzi liye laqashelwa kakhulu ngabasebenzisi bokugcina ngokuthembeka kwalo okuphezulu, uma unesithakazelo ku-Downhole Cutter ye-Vigor's Non-explosive. , sicela ungangabazi ukuxhumana nathi.
