Abapakira Kubona Ibitekerezo

1. Kurekura abapakira hamwe na manipuline ntoya, gukurura neza, cyangwa 1/3 cyo kurekura.

Inshuro nyinshi ibintu bimeze neza cyangwa ibindi bikoresho byo hepfo murugozi bituma byifuzwa ko abapakira barekurwa hamwe na manipulation nkeya cyangwa ntayo. Imyobo yatandukanijwe ni ingero zambere, mugihe kuba gazi ya eccentric ya lift itwara uruhande rwumufuka cyangwa uburebure bwa 1/4 ″ umurongo ugenzura mu mwobo byaba ingero zanyuma. Uburyo bukurura bwo kurekura uburyo nuburyo bwifuzwa cyane muribenshi. Ubusanzwe aba bapakira ni bogoshe berekanwe mumwanya washyizweho (bidasanzwe - ubwoko bumwebumwe bwo guhagarika umutima). Ubundi buryo ni uburyo bwo guhinduranya byibuze gusohora (1/3 guhindukira kubipakira) bamwe basubirana bafite. Ubwoko bwinshi bwa kashe ya bore ishobora kugarurwa irekuwe nuburemere bugororotse ariko nyuma yikimenyetso cyo gukora kimaze gukururwa. Aba bapakira bakeneye urugendo rwinyongera hamwe nigikoresho cyo kurekura kugirango bakurure abapakira. Ariko, nta guhinduranya tubing bisabwa. Abapakiye bake badasanzwe nabo barateguwe kandi biruka bikururwa neza nyuma yumurongo wa wireline wimuwe. Ihitamo ntirishobora gukundwa kuberako ubushobozi bwo gukurura paki buterwa na wireline kugera kubapakira. Kubura uburyo bwo kubona imiyoboro irashobora kuba impamvu yo gukenera gukuramo ibicuruzwa mbere.

2. Subiza inyuma ubushobozi bwo kurekura, kurekura umutekano, cyangwa kurekura.

Ibidakenewe neza neza, ibibazo byumusaruro utateganijwe, hamwe no kudahuza nibindi bikoresho byo hasi ni impamvu zose zishobora gutuma ubushobozi bwo kurekura bushobora gukenerwa. Niba uburyo bwibanze bwo kurekura budashobora cyangwa budakora kubwimpamvu runaka, ibintu nkibi biba ngombwa cyane. Rimwe na rimwe, ibyo bishoboka birashobora gutegurwa kandi ibintu nkibi bigomba gufata umwanya wambere muguhitamo abapakira. Ubwoko bukunze kurekurwa bwa kabiri ni mukwogoshesha inkweto cyangwa imigozi hamwe no gukurura. Ariko, kuzenguruka-ubwoko bwa kabiri bwo gusohora nabwo bwashyizwe mubipakira bimwe.

3. Kubitsa cyangwa gupakira kugarurwa hamwe byuzuye, bipakira bypass cyangwa flush kashe.

Ibikorwa bimwe bimwe bishobora kuvamo kuzuza mu buryo bushyize mu gaciro hejuru yabapakira. Urugero rwaba umusaruro wa zone ya kabiri hejuru yumupaki umwe muri tubing / casing annulus. Amande yatanzwe kuva muri zone yo hejuru arashobora gutura hejuru yabapakira. Mu bihe nk'ibi, abapakira bagomba gushyirwa hafi hashoboka munsi ya zone yo hejuru cyangwa amaboko yo kunyerera agomba gushyirwa hafi hashoboka hejuru yabapakira. Nubwo bimeze bityo ariko, nubwo bimeze bityo, amande amwe azagumaho kandi gusiba cyangwa gupakurura igitutu ni ingirakamaro cyane kugirango yemere igituba kuzenguruka hejuru yibintu kugirango akureho amande cyangwa imyanda. Muburyo buhoraho cyangwa kashe ya bore ishobora kugarurwa, inteko ya kashe irashobora gutanga ubushobozi bumwe. Iyi mikorere ikora neza mugihe inteko ya kashe ingana cyangwa ntoya muri OD kuruta igituba.

4. Kuringaniza igitutu kurekura abapakira, gupakurura igitutu cyangwa gutandukanya kashe.

Iyo abapakira bakoresheje ubujyakuzimu buringaniye, birashoboka cyangwa birashoboka ko itandukaniro ryinshi ryumuvuduko rishobora kubaho kubapakira nyuma yo kurekurwa. Niba umukoresha adapakurura igituba mbere yo kurekurwa, umuvuduko wamazi urashobora kuba hejuru cyane yumuvuduko wikigega cyashize igice cyitaruye. Itandukaniro riva hepfo rishobora kubaho mubindi bihe niba ikigega cyitaruye cyatewe inshinge cyangwa mubisanzwe kirakabije.

Muri ibyo aribyo byose, niba igikoresho kiringaniza igikoresho cyubwoko runaka kitaboneka, noneho haribishoboka ko kurekura abapakira bishobora kugorana, kandi / cyangwa pake yibintu byangiritse mugikorwa cyo kurekura. Nibintu byingenzi byingenzi niba abapakira bakeneye gusubirwamo murugendo rumwe. Ihitamo ryimbere-yumuvuduko-wo gupakurura ibintu biranga ni uko uburinganire bumwe bushobora gukorwa mugukuramo inteko ya kashe muburyo bwa kashe ya bore ishobora kugarurwa.

5. Kurekura abapakira nta rugendo rwa tubing, tubing ihuza neza nuwabipakira.

Nkuko byavuzwe haruguru, abapakira bamwe basaba urugendo-ruzenguruka rwa tubing kugirango bagarure inteko ya kashe hanyuma bongere gukoresha igikoresho cyo gukurura. Ibi ntabwo byemewe mubihe bimwe. Mubikorwa bimwe byatanzwe aho akazi gasanzwe gasanzwe, ubukungu bwuburyo bukurura ntibushobora kuba bufite ishingiro. Kugirango ubashe gukurura abapakira udakoze urugendo rwo kuryama, bigomba kuba byubwoko bwashizweho kugirango buhindurwe neza kuri tubing kandi ntabwo ari ubwoko bwa kashe ya kashe ishobora kugarurwa ifatanye nigituba ikoresheje igitambaro cyo guteranya kashe. . Ibidasanzwe ni verisiyo yo gusohora wireline yavuzwe mbere. Benshi murubwo bwoko bwurudodo-bapakira barashobora guhindurwa hamwe nibikoresho kugirango igituba gishobora gukururwa ukundi kubapakira hanyuma bagakomeza kugarura ibintu nta rugendo ruzenguruka.

6. Byoroshye gusya bipakira, intera ntoya, kandi ntizunguruka.

Ibikenewe byoroshye kandi byihuse gusya byuzuye bipakira biragaragara. Ibishushanyo by'ibipaki bituma ibi bishoboka harimo ibyuma bisya ibyuma, ibishushanyo mbonera byibuze intera, ibishushanyo mbonera bya OD byibuze byasya, hamwe no gufunga anti-rotation.

Ibicuruzwa bipakira ibicuruzwa bya Vigor bikozwe hakurikijwe amahame yo mu rwego rwo hejuru ya API 11D1, kandi abapakira bose kuva R&D kugeza ku musaruro kugeza kugeza ku bakiriya ba nyuma baragenzurwa kandi bakandika kugira ngo ubuziranenge bw’ibicuruzwa bushobore kubahiriza ibyo abakiriya bakeneye. Niba ushimishijwe nimbunda za Vigor zimbunda, nyamuneka ntutindiganye kuvugana nitsinda ryumwuga wa Vigor kugirango ubone ibicuruzwa byiza ninkunga ya tekiniki.
