Ngā Take me ngā Otinga mō te Ngaronga Whakawhiti WOB i roto i te Keri

1. Te Ariā, Ngā Āhuatanga me Ngā Tūponotanga o te Ngaronga Whakawhiti WOB

Ariā:I te wā e keri ana, ka nui te waku i waenganui i teaho wiriā, ka ārai te pakitara poka i te taumaha i runga i te mata (WOB) kei tukuna ki te mata keri—engari, ka pau te WOB katoa i te aho keri. Ka puta tēnei mā te korenga o te tere uru ahakoa te pikinga o te WOB, te korenga o te pēhanga whakamuri, me te iti o te taipana. Ko te otinga ko te whakaiti i te tere hurihuri me te whakanui haere i te WOB (me te whakarite kia rite ki te kaha pēhanga o te aho keri) kia piki ohorere te taipana me te puta o te pēhanga whakamuri ki runga i te WOB. I muri i te keri i ia hononga, me whakahou te reaming me te backreaming i mua i te hono i te hononga, i te tūnga rānei e whai ake nei.

Ngā Āhuatanga me ngā Tūponotanga:Ka puta tēnei raruraru i te nuinga o te wā i te wā e keri ana i te taha whakamuri i roto i ngā puna poutū, i te wā e keri ana i te taha matapihi me te taha taha, me te wā e keri ana i te taha whakapae o te puna. Ka whakararuraru i te hanganga taha noa, ā, ka piri pea ngā paipa mēnā ka kore e tika te whakahaere i ngā mahi.

2.Te Tātari i ngā Take

Te Ara o Wellbore Rawakore:Ko ngā rerekētanga o te ara o te poka wai (nā ngā āhuatanga hanganga, ngā hapa hanga rānei) he maha ngā wā e hiahiatia ana he whakatikatika whakamuri. Ko ngā tere hanga teitei (he mea noa ake i roto i ngā poka whakapae reo-poto/poto te whānui i ngā mea roa-roa) me ngā ara koretake, me te pakari o te aho keri, ka meinga te aho keri kia tau ki te pakitara o te poka wai ina pēhia te pēhanga—ka puta ai te ngaronga o te whakawhiti WOB. Ko te kaha kukume tāpiri i te wā e hinga ana i muri i te pēhanga he rite ki ngā taumata noa, ā, kāore i te nuinga o te wā e neke ake i te pēhanga ki raro.

Puna Pāwera (Te Hanganga o te Moenga Tapatapahi):He uaua te tango i ngā tapahi i roto i ngā puna ahunga me ngā puna whakapae he koki poka 45–90 nekehanga. I roto i ngā hanganga mārō (hei tauira, ngā hanganga Shahejie me Kongdian), ka tere te kohikohi o ngā tapahi ki roto i ngā moenga. Ka whakanui ake ēnei moenga i te waku reti i waenga i te aho keri me te pakitara o te poka, ka hua ake te ngaronga o te whakawhiti WOB.

Keke Paru Matotoru, Wetekina, Tauwehenga Waku Paru Teitei:Ko te nui o te totoka i roto i te paru ka hua ake he matotoru, he koretake ngā keke paru, ka whānui ake te wāhi e pā ana ki te aho keri, ā, ka piki ake te tūponotanga o te piri. Ka whakanui ake te tauwehenga waku paru i te ātete paheke o te aho keri. Tērā pea ka āraia ohoreretia te papu e tēnei āhuatanga ina whakanuia te WOB (hei tauira, ki te 30 tana), me te kaha kukume tāpiri e nui ake ana i te WOB ki raro.

3. Ngā Mahi Whakaiti

Te Whakahaere Ara o te Pūaha me te Arotautanga o te Aho Wiri:Whakatinanahia te keri mata-ārahi katoa hei karo i ngā pekapeka e hiahia ana kia whakatikatikahia te rere whakamuri. Whakangawaritia te whirihoranga aho keri (whakaitihiangā kara wiri((whakanuia ake ngā paipa wiri taumaha) hei whakaiti i te pakari me te whakaiti i te pa ki te keke paru, hei ārai i te ngaronga o te whakawhiti WOB me te piri.

Whakarei ake Te Whakamaemae i te Puna me te Paru:Whakamahia ngā taputapu whakahaere totoka hei pure i te paru mata. Kia nui te nekehanga (kaua e iti iho i te 3.4 m³/min mō ngā wāhanga poka φ311, 1.1 m³/min mō ngā wāhanga φ216) me te whakatika i ngā tawhā reological paru (ōwehenga YP/PV: 0.42–0.50; matotoru: ≥48 s) hei whakapai ake i te kaha kawe tapahi. Mō ngā poka whakapae, whakatōkia ki te 20–30 nekehanga o te pekapeka hei wawahi i ngā moenga tapahi.

Whakapai ake i te Hinu o te Paru me te Kounga o te Keke Paru:Tāpirihia kia 3–5 tāne o te hinu mata (kaua e neke atu i te 10%) me ngā hinu whakahinuhinu wai hei whakataurite i te whakahinuhinu me te kounga o te keke paru. Tāpirihia he uku whanariki, he kapia phenolic rānei hei whakapai ake i ngā āhuatanga o te keke paru. Mō te ngaronga whakawhiti WOB i roto i ngā hanganga mārō, tāpirihia he 200–300 kg o te karāwhata whānui, he hinu whakahinuhinu pēhanga nui rānei hei whakaiti i te waku.
