Te whakarōpūtanga me te kōwhiringa o te aukati pupuhi

Ko te taputapu tino nui hei mārama ki te mahi a ngā taputapu whakahaere puna, hei tāuta me te tiaki tika, me te whakahaere i te mahi tika a ngā taputapu whakahaere puna ko te aukati pupuhi. E rua ngā momo aukati pupuhi e whakamahia whānuitia ana: te aukati pupuhi mowhiti me te aukati pupuhi rama.

1. Ārai mowhiti

(1) Ina he aho paipa kei roto i te puna, ka taea te whakamahi i te matua rapa hei kati i te āputa porowhita i hangaia e te aho paipa me te pane puna;

(2) Ka taea te hiri katoa i te pane o te poka ina takoto kau te puna;

(3) I roto i te mahi keri me te mira, te huri anga, te rakau me te hī ika ki raro, mēnā ka puea ake, ka pupuhi rānei, ka taea te hiri i te wāhi i hangaia e te paipa Kelly, te taura, te taura waea, ngā taputapu whakahaere aituā me te pane puna;

(4) Mā te kaiwhakahaere pehanga, te iti rānei o te rokiroki pūngao, ka taea e ia te pana i te hononga paipa kua whakarewahia me te kore he whitiki angiangi i te 18°;

(5) Mēnā he nui te waipuke, te pahūtanga rānei, ka whakamahia hei whakatutuki i te kati ngāwari me te rama BOP me te manifold throttle.

2. Ārai pahūtanga Ram

(1) Ina he taputapu keri kei roto i te puna, ka taea te whakamahi i te hipi hiri-haurua e rite ana ki te rahi o te taputapu keri hei kati i te āputa mowhiti o te pane puna;

(2) Ina kāore he taputapu keri i roto i te puna, ka taea e te hiri hiri katoa te hiri katoa i te pane o te puna;

(3) Ina hiahiatia te tapahi i te taputapu keri i roto i te puna, me te hiri rawa i te pane o te puna, ka taea te whakamahi i te hipi kutikuti hei tapahi i te taputapu keri i roto i te puna, me te hiri rawa i te pane o te puna;

(4) Mā te rama o ētahi ārai pupuhi rama ka taea te kawe kawenga, ā, ka taea te whakamahi hei whakairi i ngā taputapu keri;

(5) He kōhao taha kei te anga o te BOP hipi toa, ka taea te whakamahi i te pōkai taha hei whakaiti i te pēhanga;

(6) Ka taea te whakamahi i te Ram BOP mō te hiri i te puna mō te wā roa;

3. Kōwhiringa o ngā huinga BOP

Ko ngā mea matua hei whakaaroaro māu i te wā e whiriwhiri ana i te huinga ārai pupuhi waipēhi ko: te momo poka, te pēhanga hanganga, te rahi o te anga, te momo wai hanganga, te pānga ki te āhuarangi, ngā whakaritenga tiaki taiao, me ētahi atu.

(1) Te kōwhiringa o te taumata pēhanga

Ko te nuinga o te wā, ka whakatauhia tēnei e te pēhanga nui rawa atu o te pane puna e tika ana kia tū atu te huinga BOP. E rima ngā taumata pēhanga o te BOP: 14MPa, 21MPa, 35MPa, 70MPa, 105MPa, 140MPa.

(2) Kōwhiringa ara

Ko te whānui o te huinga BOP e whakawhirinaki ana ki te rahi o te anga i roto i te hoahoa hanganga o te puna, arā, me paku nui ake i te whānui o waho o te anga e piri ana. E iwa ngā momo whānui ārai pupuhi: 180mm, 230mm, 280mm, 346mm, 426mm, 476mm, 528mm, 540mm, 680mm. I roto i ēnei, ko te 230mm, 280mm, 346mm me te 540mm e whakamahia whānuitia ana i te mara.

(3) Kōwhiringa o te āhua whakakotahi

Ko te kōwhiringa o te momo whakakotahitanga e ahu mai ana i te pēhanga hanganga, ngā whakaritenga tukanga keri, te hanganga taputapu keri me ngā āhuatanga tautoko taputapu.
