Gufungura Byuzuye Umutekano Valve (FOSV)

Gufungura Byuzuye Umutekano Valve (ngufi kuri FOSV) numupira wumutekano wumupira ukoreshwa kugirango uhagarike gutembera mumurongo wimyitozo mugihe umugozi wimyitozo urimo gukurwa kuriba.

FOSV ni umubiri wibiri-ufunguye umutekano wumutekano, ntabwo rero bibangamira ikoreshwa ryibikoresho nka barrele yibanze cyangwa ibikoresho byubushakashatsi. Yashizweho kugirango yatewe icyuma hejuru yumuringoti wa dring cyangwa umugozi wa tubing hasi hanyuma ugafungwa vuba mugihe iriba ryateye.

Mugihe utumiza nyamuneka sobanura:
Kwihuza.

Umuvuduko w'akazi: 5.000 / 10,000 / 15,000 PSI;

Kelly valve

Kelly valve nayo yitwa Kelly isake cyangwa Gray valve. Nibikoresho bigenzura intoki muri sisitemu yo kuzenguruka ya drill kandi ni kimwe mubikoresho bifatika byo gukumira umuyaga. Umuyoboro wa Kelly ugabanijwe hejuru ya Kelly Valve na Kelly Valve yo hepfo. Hejuru Kelly Valve ihujwe na swivel sub na Kelly. Umuyoboro wo hasi wa Kelly uhujwe nu mpera yo hepfo ya Kelly no hejuru ya pipe ya drill cyangwa impera yo hepfo ya Kelly ikiza sub. Kuzenguruka umugozi wuzuye wo gufungura umutekano wuzuye 90 ° kugirango umenye no kuzimya. Mubikorwa byo gucukura, kugirango hirindwe impanuka mbi, indangantego za Kelly zigomba guhuzwa kumpande zombi za Kelly kugirango hirindwe gutakaza flide yo gucukura no guturika. Kelly cock valve, nigikoresho gikoreshwa nintoki zikoreshwa mumashini ya ID ya mugozi wa drill, Nimwe mubikoresho bifatika byo kwirinda guturika.

Isake ya kelly igabanijwemo hejuru ya kelly cock valve na kelly yo hepfo.
Isake yo hejuru ya kelly ihujwe nu mpera yo hepfo ya swivel nu mpera yo hejuru ya kelly. Isake yo hepfo ya kelly ihujwe nu mpera yo hejuru ya drill nu mpera yo hepfo ya kelly cyangwa ihujwe hagati yumutwe wa kelly saver subs.
Isake ya kelly igaragaramo imikorere yoroshye, isake ya kelly irashobora guhindurwa cyangwa guhindurwa muguhindura gusa imikorere idasanzwe ya dogere 90 kuri dogere ukurikije icyerekezo. Mugihe cyo gucukura inkoko ya kelly igomba guhuzwa kumpera yo hejuru no hepfo ya kelly.

Mugihe utumiza nyamuneka sobanura:
Ubwoko bwo hejuru cyangwa Hasi;
Igikoresho OD;
Umuvuduko w'akazi: 5.000 / 10,000 / 15,000 PSI;
Guhuza ibikoresho.

Imbere muri BOP

Imbere yo gukumira ibicuruzwa (Imbere muri BOP) nigikoresho kidasanzwe, gishobora kunyuzwa muri BOP mbere yo guhuzwa nibikoresho byongeweho gucukura vuba bishoboka, mugihe ibisasu bibaye mugihe cyo guterura ibikoresho byo gucukura, uwirinda imbere afite byinshi ibyiza nkumuvuduko mwinshi, bifunze byizewe, byoroshye gukora, hindura vuba nibindi.

Mugihe utumiza nyamuneka sobanura:
Igikoresho OD;
Umuvuduko w'akazi: 5.000 / 10,000 / 15,000 PSI;
Guhuza ibikoresho.

Mugihe igikoresho cyo gutobora gisohoka mu mwobo, guturika bibaho kubera ibisubizo byokunywa, Iyo amazi, amavuta, amavuta cyangwa amazi bivuye mumiyoboro ya drillage yasohotse, birinda imbere bigomba guhita bihuzwa numuyoboro wimyitozo, Imbere gukumira umuyaga birashobora guhuzwa byoroshye numuyoboro wimyitozo bitewe nuko valve yo gukumira ibicuruzwa bihagaze neza kandi amazi yo mu mwobo ashobora gutembera imbere mu gukumira umuyaga uhagaze kandi amazi yo mu mwobo ashobora gusohoka. y'imbere yo gukumira ibicuruzwa, Inkoni yubutabazi irashobora gufunga valve mugukuramo icyuma gifunga, ubungubu, icyuma gikingira imbere cyemerera amazi gutoborwa mu mwobo kuva hejuru kugeza hasi, ariko amazi yo mu mwobo ntashobora kwinjira. umugozi wimyitozo hanyuma amaherezo usohokane imbere yikumira ryimbere Noneho intego yo gukumira ibizunguruka igerwaho nintambwe zikurikira, Gusohora ubutabazi bugenga amazi hanyuma ugatangira kuzenguruka pompe.

Kugabanuka-kugenzura cheque

Kugabanuka-Kugenzura Valves birinda kugaruka mugihe cyo gutera kandi birakwiriye mubihe byinshi byo gucukura aho kugaruka gutembera mumurongo wimyitozo ari akaga kandi imikorere isanzwe isaba inyungu za sub-bore sub. Mu gukumira gutembera hejuru unyuze mu muyoboro wa drillage, ariko ukemerera amazi gutwarwa hepfo kugirango azenguruke iriba, indiba zitanga umwitozo uburyo bwo kugenzura imiyoboro yimiyoboro iyo bibaye ngombwa, bitezimbere kandi byoroshe kugenzura iriba.

Iyo blowout igiye kuba connections guhuza urudodo rwa kelly birahita bisohoka hanyuma ugashyira cheque ya cheque iri mumiyoboro ya drillage hanyuma igahita imanuka hepfo ahabigenewe.Noneho birashobora gukumirwa.

Mugihe utumiza nyamuneka sobanura
Gitoya irambuye mumurongo wimyitozo unyuzamo cheque valve igomba kunyuramo.
Kumanura sub ihuza ingano nubwoko.
Hanze ya diameter yo guhuza ibikoresho.

Umuhengeri

Kureremba kureremba birinda amazi yo gutobora, gutema hamwe n imyanda yicyuma gutembera hejuru yumurongo wimyitozo. Iyo ushyizwe neza kumurongo wimyitozo iyi valve itanga hongeweho gukumira.

Kureremba kureremba birashobora gukoreshwa ahantu hose kuva hejuru kugeza hepfo ya drillstring. Nibisanzwe cyane ni muri BHA (guteranya umwobo wo hasi) urimo bito, kandi irashobora gushiramo bito, hafi ya stabilisateur ya biti, izindi stabilisateur, kureremba hejuru, kwambukiranya sub, moteri yicyondo (hejuru ya sub), cola cola, n'umuyoboro. Imyanya myinshi ireremba irashobora gukoreshwa mumurongo umwe, nubwo gutondekanya kabiri ntabwo byemewe kubera kwangirika kwamazi ya flat mugihe cyumuvuduko mwinshi. Ahubwo, tandukanya indangagaciro mubikoresho bitandukanye.

Umuyoboro wa drill (DP) Indangantego zireremba ziraboneka kubikorwa bisanzwe, serivisi ya H2S - 300 ° F (HNBR / HSN) na H2S - 400 ° F (Viton.)
