Nhazi na nhọrọ nke ihe mgbochi ịfụfụ

Ngwá ọrụ kachasị mkpa iji ghọta arụmọrụ nke akụrụngwa na-achịkwa nke ọma, wụnye ya n'ụzọ ziri ezi ma na-edozi ya, na-eme ka ihe nchịkwa nke ọma na-arụ ọrụ ya nke ọma bụ ihe mgbochi nkwụsị. Enwere ụdị ihe mgbochi abụọ a na-ahụkarị: ihe mgbochi mgbanaka mgbanaka na ihe mgbochi ebule.

1.Mgbochi mgbanaka

(1) Mgbe enwere eriri ọkpọkọ na olulu mmiri ahụ, enwere ike iji eriri roba mechie oghere anular nke eriri ọkpọkọ na isi mmiri na-emepụta;

(2) Enwere ike mechie isi olulu mmiri ahụ mgbe olulu mmiri tọgbọ chakoo;

(3) N'ime usoro ịkụ ala na igwe nri, ịkwanye casing, ịkụ osisi na ịkụ azụ, ọ bụrụ na oke mmiri na-ejupụta ma ọ bụ na-agbapụta, ọ nwere ike mechie oghere nke kelly pipe, eriri, eriri waya, ihe eji eme ihe mberede na isi mmiri;

(4) Na nrụgide enyemaka regulator ma ọ bụ obere nchekwa nchekwa, ọ nwere ike ịmanye butt welded ọkpọkọ ọkpọkọ na-enweghị ezigbo eriri na 18 °;

(5) Ọ bụrụ na oke oke njupụta ma ọ bụ ọfụfụ, a na-eji ebule BOP na throttle manifold wee nweta mmechi dị nro.

2.Ram blowout mgbochi

(1) Mgbe e nwere ngwá ọrụ ndị na-egwupụta ihe na olulu mmiri ahụ, ebulu ahụ nke na-ekpuchi ọkara nke kwekọrọ na nha nke ihe ọkụkụ nwere ike iji mechie oghere mgbanaka nke isi mmiri;

(2) Mgbe ọ na-enweghị ngwá ọrụ mkpọpu n'olulu mmiri ahụ, ebule ahụ zuru ezu nwere ike mechie isi olulu mmiri ahụ kpamkpam;

(3) Mgbe ọ dị mkpa iji belata ngwá ọrụ na-egwupụta ihe na olulu mmiri ahụ ma mechie isi mmiri ahụ kpamkpam, a pụrụ iji ebule na-agbapụta ihe na-egbutu ihe na-emepụta ihe na olulu mmiri ma mechie isi mmiri ahụ kpamkpam;

(4) Ebulu nke ụfọdụ ihe mgbochi ebule nke na-enye ohere ibu ibu ma nwee ike iji kwụsịtụ ngwaọrụ egwu egwu;

(5) Enwere oghere n'akụkụ n'elu shei nke ebule BOP, nke nwere ike iji oghere n'akụkụ na-eme ka nrụgide nrụgide;

(6) Enwere ike iji Ram BOP maka mkpuchi nke ọma ogologo oge;

3.Nhọrọ nke mkpokọta BOP

Isi ihe ndị a ga-atụle na nhọrọ nke hydraulic blowout mgbochi nchikota bụ: ụdị nke ọma, nrụgide nhazi, nha casing, ụdị mmiri mmepụta ihe, mmetụta ihu igwe, ihe nchebe gburugburu ebe obibi chọrọ, wdg.

(1) Nhọrọ nke ọkwa nrụgide

A na-ekpebi nke ọma site na nrụgide isi mmiri kachasị elu nke a na-atụ anya na ngwakọta BOP ga-eguzogide. Enwere ọkwa nrụgide ise nke BOP: 14MPa, 21MPa, 35MPa, 70MPa, 105MPa, 140MPa.

(2) Nhọrọ nke ụzọ

Dayameta nke nchikota BOP na-adabere n'ụdị casing na nhazi nhazi nke ọma, ya bụ, ọ ga-adị ntakịrị karịa elu elu nke mkpuchi nke a na-ejikọta ya. E nwere ụdị itoolu nke ihe mgbochi ihe mgbochi: 180mm, 230mm, 280mm, 346mm, 426mm, 476mm, 528mm, 540mm, 680mm. N'ime ha, 230mm, 280mm, 346mm na 540mm na-ejikarị eme ihe n'ọhịa.

(3) Nhọrọ nke ụdị nchikota

Nhọrọ nke ụdị nchikota na-adabere na nrụgide nhazi, usoro ihe ọkụkụ chọrọ, usoro ihe ọkụkụ na ngwá ọrụ na-akwado ọnọdụ.
