He aha ka UCBV (Pūnaewele Kūʻai ʻAʻohe palena)?

ʻO ka pahu kaʻa kaʻa palena ʻolehe pūʻulu o nā ʻāpana pōkole hiki ke wehe a pani i nā manawa he nui, maʻamau i hoʻokomo ʻia i nā hui ʻana o nā mea hana hoʻoheheʻe kūikawā e like me ka orientation, acceleration, a me ka hoʻopaʻa ʻana i ka wā e wili ana, hiki ke wehe a pani i nā puka bypass i ka manawa e like me nā kūlana downhole no nā hana kūikawā, e hoʻonui i ka hoʻohana ʻana o nā hui pū ʻana o nā mea hana wili kūikawā, kōkua i ka hoʻomaikaʻi ʻana i ka hana ʻana, a e hōʻemi i nā pilikia hoʻomalu maikaʻi.

I nā hana downhole, e like me ka leak plugging, acid injection, workover, a me ka hoʻopau ʻana, hiki i nā hana he nui o ka bypass valve ke pale i ka hui pū ʻana o nā mea hana hoʻoheheʻe downhole.ʻO ka pahu kaʻa kaʻa palena ʻolehiki ke kōkua i ka hoʻomaikaʻi ʻana i ka ʻoki ʻana i ka hana hoʻonui ʻana i ka maka, hoʻomaikaʻi i ka kahe kahe o ka annular i ka luawai a me ke kuhikuhi ʻana i ka luawai, a hoʻonui i ka hiki ke hoʻomaʻemaʻe i ka ʻaoʻao haʻahaʻa o ka pā luawai.

ʻO nā pono ʻenehana nui oka pahu hopu kaiapuni palena olepenei:

(1) Hiki iā ia ke hoʻomaopopo i nā hana kūikawā e like me ka wili ʻole a me ka hoʻopili ʻana, a hoʻopōkole i ka pōʻaiapili wili;

(2) E pani 'akomi 'ia ka valve bypass i ka wā i pani 'ia ai ka pama no ka pale 'ana i ka hopena paipu U-like a i 'ole nā ​​pilikia ho'omalu maika'i;

(3) ʻAʻole i kaupalena ʻia e ka lua wai o nā mea hana downhole, nā mea kani, a me nā ʻāpana drill, a hiki ke hoʻomaopopo i ka holoi ʻana i ka holoi maikaʻi;

(4) Hiki iā ia ke wehe maikaʻi i ka moena pōhaku o nā pūnāwai kuhikuhi a me nā luawai pae;

(5) Hiki iā ia ke pale pono i nā mea kani downhole a me nā mea hana wili mana
