Lāʻau Kalikimaka (Lāʻau Kalikimaka ʻo Wellhead)

ʻIke Kumu o nā Lāʻau Kalikimaka Ma luna o ka ʻIli (Nā Lāʻau Maloʻo)

Ma ka ʻoihana aila a me ke kinoea kūlohelohe, ʻo ka "Lāʻau Kalikimaka" e pili ana i kahi moʻo o nā kiwikā a me nā ʻākoakoa spool i hoʻokomo ʻia ma luna o kahi luawai aila. No nā luawai ʻāina, ua hoʻokomo ʻia ma luna o ka spool casing hope loa; no nā luawai subsea, ua hoʻokomo ʻia ma luna o ka ʻākoakoa poʻo luawai kiʻekiʻe. Hōʻike ka Kiʻi 1 i kahi kiʻikuhi schematic o kahi "Lāʻau Kalikimaka" a me ka ʻākoakoa poʻo luawai ʻili. Aia ka ʻāpana Lāʻau Kalikimaka ma luna (i loko o kahi pahu polū), ʻoiai ʻo ka ʻāpana poʻo luawai ka ʻāpana lalo (i loko o kahi pahu ʻulaʻula). He nui ka poʻe e huikau i nā manaʻo o "Lāʻau Kalikimaka" a me "poʻo luawai," me ka manaʻo pinepine he mea like lāua.

Eia kāna mau hana:

1. No ka lawe maluhia ʻana i nā wai waihona mai ka luawai a i ka ʻilikai ma ke ʻano i kāohi ʻia.
2. I mea e hāʻawi ai i ke komo palekana i ka luawai no ka hana ʻana i nā kaʻina hana hana luawai.
3. No ka ʻae ʻana i nā hana hoʻokomo wai a kinoea paha.
4. No ka hoʻolako ʻana i nā pilina laina hydraulic no ka kaohi ʻana i nā kiwikā palekana downhole (SCSSSV).
5. E hāʻawi i nā pilina uila no nā mea hana a me nā lako o nā Pumps Hoʻokomo Wai Uila (ESP).

Ke hoʻolauna nei kēia ʻāpana i kahi "Lāʻau Kalikimaka" ma luna (lāʻau maloʻo), e pili ana i kekahi lāʻau i loaʻa ma luna o ka laina wai. Aia kahi Lāʻau Kalikimaka i kahi moʻo o nā kiwikā, me kona mau ʻāpana i wehewehe ʻia ma lalo nei.

Kiwikā Kumu

Aia kahi kiwikā haku ma luna o ka mea kau paipu a lawelawe ia e ʻae i ka hana maʻamau o ka luawai a i ʻole e pani i ka luawai. ʻO ka maʻamau, aia ʻelua mau kiwikā haku: ʻo kekahi i kapa ʻia ʻo Lower Master Valve, a ʻo kekahi ʻo Upper Master Valve. Hoʻohana pinepine ʻia ʻelua mau kiwikā e hāʻawi i ka redundancy; inā hāʻule kekahi, hiki i kekahi ke lawe i kāna hana. Hōʻike nā Kiʻi 2 a me 3 i nā kiʻikuhi maʻalahi o kahi kiwikā haku hoʻokahi a me nā kiwikā haku pālua.

Tee (Poloka-T)

ʻO ka Tee (poloka-T) e ʻae i ke kahe o ka wai e hoʻohuli ʻia mai ka paipu kū pololei i ka paipu ʻauwai.

Kiʻi 4- Ke kūpono ʻano T

Kiwikā ʻēheu (ʻEheu Kahe)

Aia kahi kiwikā ʻēheu ma ka ʻaoʻao o ka hui "Christmas Tree" a kāohi a hoʻokaʻawale paha i ke kahe o ka hana luawai i nā hale hana ma luna. Ma muli o ka hoʻolālā o ka "Christmas Tree," hiki ke hoʻolako ʻia me hoʻokahi a ʻelua paha mau kiwikā ʻēheu. Pono kekahi poʻe lawelawe i ʻelua mau kiwikā ʻēheu hana—hoʻokahi ma ke ʻano he kiwikā hana mua a ʻo kekahi ma ke ʻano he kākoʻo (e nānā i ke Kiʻi 5). I nā hihia he nui, hoʻohana ʻia kekahi kiwikā ʻēheu no ka hana ʻana, a lawelawe kekahi ma ke ʻano he kiwikā ʻēheu pepehi (e nānā i ke Kiʻi 6).

ʻUmiʻumi

ʻO ka "choke" ka ʻāpana hoʻopaʻa liʻiliʻi loa i loko o ka Lāʻau Kalikimaka, e hana ana e kāohi i ka wikiwiki o ka hana ʻana o ka luawai ʻaila. I kekahi mau hihia, hoʻohana ʻia nō hoʻi ia e kāohi i ka hana ʻana o ke one. Hoʻopaʻa ka "choke" i ka wahi kahe o ka ʻaila ma ka hoʻokomo ʻana i kahi cylinder liʻiliʻi a i ʻole orifice i loko o ke kino choke. ʻO ka liʻiliʻi o ke anawaena o ka cylinder, ʻo ka haʻahaʻa o ka wikiwiki o ka hana ʻana. ʻElua ʻano o nā choke: 1) Positive Choke (nā cylinders hiki ke hoʻololi ʻia) a me 2) Adjustable Choke (maʻalahi ke hoʻoponopono i ka nui o ka choke).

Kiwikā Swab

Aia kahi kiwikā swab ma ka piko loa o ka ʻākoakoa Lāʻau Kalikimaka, e hāʻawi ana i kahi ala kū pololei i loko o ka luawai no ka hana wireline, slickline, coiled tubing, a i ʻole nā ​​​​hana pamu koʻokoʻo.

Nā Pāpale Tee a me nā Ana Paʻi

ʻO ka T-Cap kahi flange i loaʻa ma ka piko o ka valve swab, e ʻae ana i ka hoʻopili ʻana o nā lubricators wireline a i ʻole nā ​​​​​​ʻāpana tubing/swabbing coiled Blowout Preventers (BOP) i ka luawai no ka hana ʻana i nā hana hana luawai. Hoʻohana ʻia nā anakahi kaomi e nānā i ke kaomi o ka luawai. I kēia mau lā, hoʻohana pinepine ka hapa nui o nā mea hana i nā anakahi kaomi uila e hoʻouna i ka ʻikepili kaomi a/a i ʻole ka mahana ma o nā ʻōnaehana uila no ka nānā maikaʻi ʻana i ka luawai.
