Rākau Kirihimete (Rākau Kirihimete o Wellhead)

Te Mātauranga Taketake mō ngā Rākau Kirihimete Mata (Ngā Rākau Maroke)

I roto i te umanga hinu me te hau māori, ko te "Rākau Kirihimete" e pā ana ki tētahi raupapa o ngā takirere me ngā huihuinga pōro kua tāutahia ki runga i tētahi puna hinu. Mō ngā puna whenua, ka tāutahia ki runga i te pōro anga whakamutunga; mō ngā puna raro moana, ka tāutahia ki runga i te huihuinga pane puna pēhanga-teitei. Kei te Whakaahua 1 te hoahoa kauwhata o tētahi "Rākau Kirihimete" me te huihuinga pane puna mata. Kei runga te wāhanga Rākau Kirihimete (i roto i tētahi pouaka kikorangi), ko te wāhanga pane puna ko te wāhanga o raro (i roto i tētahi pouaka whero). He maha ngā tāngata e whakapoauau ana i ngā ariā o "Rākau Kirihimete" me "pane puna", e whakapono ana he rite tonu rāua.

Ko āna mahi penei:

1. Hei kawe haumaru i ngā wai o te puna wai mai i te puna ki te mata o te puna i runga i te tikanga whakahaere.
2. Hei whakarato i te urunga haumaru ki te poka wai hei whakahaere i ngā tukanga wawaotanga puna.
3. Hei whakaae i ngā mahi werohanga wai, hau rānei.
4. Hei whakarato hononga raina waipēhi mō te whakahaere i ngā takirere haumaru o raro (SCSSSV).
5. Hei tuku atanga hiko mō ngā taputapu me ngā taputapu o ngā Papu Hiko Ruku (ESP).

Kei roto i tēnei wāhanga he "Rākau Kirihimete" mata (rākau maroke), e pā ana ki tētahi rākau kei runga ake i te raina wai. He raupapa takirere te Rākau Kirihimete, me ōna wāhanga e whakamāramahia ana i raro nei.

Takirere Matua

Kei runga ake i te whakairi ngongo he takirere matua, ā, ka taea te whakahaere i te puna i te huarahi noa, te kati rānei i te puna. I te nuinga o te wā, e rua ngā takirere matua: ko tētahi e kiia ana ko te Takirere Matua o Raro, ko tētahi ko te Takirere Matua o Runga. E rua ngā takirere e whakamahia whānuitia ana hei whakarato i te auautanga; ki te kore tetahi e mahi, ka taea e tētahi te tango i tana mahi. E whakaatu ana ngā Pikitia 2 me te 3 i ngā hoahoa ngāwari o te takirere matua kotahi me ngā takirere matua takirua.

Tī (Poraka-T)

Mā te T (poraka-T) ka taea te huri i te rere o te wai mai i te paipa poutū ki te paipa whakapae.

Pikitia 4- Te hononga momo T

Takirere Parirau (Parirau Rere)

Kei te taha o te huihuinga "Rākau Kirihimete" tētahi takirere parirau, ā, ka whakahaere, ka wehe rānei i te rere o te whakaputanga puna ki ngā whare mata. I runga anō i te hoahoa o te "Rākau Kirihimete," ka taea te whakauru i tētahi, i ētahi rānei takirere parirau. E rua ngā takirere parirau whakaputa e hiahiatia ana e ētahi kaiwhakahaere—ko tētahi hei takirere whakaputa matua, ko tētahi hei tārua (tirohia te Pikitia 5). I roto i te nuinga o ngā wā, ka whakamahia tētahi takirere parirau mō te whakaputa, ā, ko tētahi hei takirere parirau whakamate (tirohia te Pikitia 6).

Kōroke

Ko te "choke" te wāhanga aukati iti rawa o te Rākau Kirihimete, e mahi ana hei whakahaere i te tere whakaputa o te puna hinu. I ētahi wā, ka whakamahia hoki hei whakahaere i te whakaputa onepu. Ka whakawhāitihia e te "choke" te rohe rere o te hinu mā te whakauru i tētahi rango iti, i tētahi kōhao rānei ki roto i te tinana choke. Ko te iti o te diameter o te rango, ko te iti iho o te tere whakaputa. E rua ngā momo choke: 1) Positive Choke (ngā rango ka taea te whakawhiti) me te 2) Adjustable Choke (he ngāwari ki te whakarite i te rahi o te choke).

Takirere Horoi

Kei te tihi rawa o te huihuinga Rākau Kirihimete he takirere ūkui, e whakarato ana i te ara poutū ki roto i te puna mō ngā mahi waea, raina maeneene, ngongo kopikopiko, papu tokotoko rānei.

Taupoki Tī me ngā Ine Pēhanga

Ko te T-Cap he flange kei te tihi o te takirere swab, e taea ai te hono i ngā hinu whakahinuhinu waea, i ngā ngongo/wāhanga swabbing rānei, arā, ko ngā Blowout Preventers (BOP) ki te puna hei whakahaere i ngā mahi wawaotanga puna. Ka whakamahia ngā ine pēhanga hei aroturuki i te pēhanga o te puna. I ēnei rā, ko te nuinga o ngā kaiwhakahaere e whakamahi ana i ngā ine pēhanga hiko hei tuku raraunga pēhanga me/ranei te pāmahana mā roto i ngā pūnaha hiko hei aroturuki pai ake i te puna.
