Ngā Pātai Auau
1. He aha te methane i roto i te waro, ā, he aha tōna rerekētanga mai i te hau māori tuku iho?
Ko te methane waro (CBM) he hau māori e rongoatia ana i roto i ngā papa waro, ko te nuinga he hau e piri ana ki te mata o te waro. Kāore i rite ki te hau māori tuku iho, e kitea ana hei hau kore utu i roto i ngā puna toka porous pērā i te onepū me te warokawa, he iti te porousity me te permeability o te CBM. Ko te tikanga he piri tonu te here o te hau, ā, ko te tangohanga e whakawhirinaki ana ki te tango wai me te whakaiti i te pēhanga hei tuku i te methane mai i te anga waro. He rerekē ake hoki ngā puna CBM, he maha ngā wā kei roto te methane biogenic, thermogenic rānei. He mea nui te pakaru waipēhi mō te hanga CBM, me te whakahaere tupato i te rere hoki me te pakaru gel hei whakanui ake i te whakaora hau me te whakaiti i te kino o te hanganga.
2. He aha te pakaru o te ira i roto i te tukatuka wai pakaru?
Ko te pakaru o te irahiko e pā ana ki te tukanga pakaru matū o ngā wai pakaru matotoru-teitei e whakamahia ana i te wā o te pakaru waipēhi. Ko ēnei wai, he mea whakamātotoru ki ngā pūmua, ka werohia ki roto i te puna hei hanga pakaru me te kawe i te onepu, i te mea whakarewa rānei. I muri i te pakaru, ka tāpirihia ngā pakaru irahiko—ko te nuinga he whākōkī, he matūriki nano, he matū rānei—hei whakaiti i te matotoru mā te wawahi i ngā mekameka pūmua. Kia pakaru te irahiko, ka huri te wai ki te matotoru-iti, ka taea ai te rere pai, te whakaiti i ngā toenga, me te whakapai ake i te hanga methane.
3. He aha te āwhina a te aroturukitanga matotoru wā-tūturu ki te pakaru o te wai ira?
Mā te aroturukitanga matotoru ā-wā tonu ka whakaratohia he raraunga tonu, tonu hoki mō te matotoru o ngā wai pakaru i te wā e pakaru ana te ira. Mā tēnei ka taea e ngā kaiwhakahaere te:
- Whakatauhia marietia te pūwāhi pakaru o te kirimi, ā, āraia te pakarutanga kāore i oti.
- Whakatikatikahia te horopeta o te pakaru tiēre kia hihiri, kia kore ai e nui rawa te whakamahinga o te pakaru, e kore rānei e tika te maimoatanga.
- Kitea ngā panonitanga kino (te matotoru nui, te poke) ka tere te urupare atu.
- Arotauhia te rere o te wai pakaru kia tere ake ai, kia ma ake ai te whakaora, kia pai ake ai hoki te whai huatanga o te tango CBM.
Hei tauira, i roto i ngā puna CBM, ka ārahihia e ngā waea hiko me ngā pūoko o raro te wā me te horopeta o te werohanga o te kaiwehe ira, ka whakaitihia ngā mōrearea whakahaere me ngā wā huringa.
4. He aha te hiranga o te arotau i te horopeta o te pakaru tiēre i roto i te tangohanga methane i runga i te moenga waro?
He mea nui te horopeta tika o te kaiwhatu tiēre kia tino memeha ai ngā pūhui tiēre, me te kore e kino ki te puna wai. Mēnā he iti rawa te horopeta, ka ārai pea ngā toenga tiēre i ngā āputa, ka whakaiti i te urunga me te whakaputanga methane. Mēnā he nui rawa te whakamahinga o te kaiwhatu, ka tere te heke o te matotoru, ka kino rānei ngā matū. Ko ngā horopeta kua arotauhia—he maha ngā wā ka tutuki mā te whakamahi i ngā matūriki nano tuku-roa, ngā whākōkī-koiora rānei—ka puta:
- Te iti rawa o te kino o te hanganga me te pupuri toenga
- Te rere pai o te wai pakaru
- He iti ake ngā utu maimoatanga wai i muri i te rerenga mai
- Te whakapai ake i te mimiti o te methane me te hua whānui.
5. He aha ngā take me ngā tūponotanga noa o te pakaru o te ira koretake i roto i te tangohanga CBM?
Tērā pea ka puta te pakaru kore o te irahiko nā:
- Kāore i te rawaka te kukū o te pakaru tiēre, te wā hē rānei
- Te koretake o te ranunga me te tohatoha o te wai i roto i te poka wai
- Ngā āhuatanga kino o te puna wai (pāmahana, pH, matū wai)
Ko ngā tūponotanga ko:
- Te matotoru nui o te wai e hoki whakamuri ana, e ārai ana i te horoi
- Ko ngā pūmua toenga e ārai ana i ngā awaawa pūwero, e kino ai te hanganga
- He iti ake ngā tere whakaora o te methane nā te mea he iti ngā ara mimiti
- Te pikinga o ngā utu mō te maimoatanga wai me te whakaora i ngā puna
Hei tauira, mā te whakamahi i ngā wawahi matū tuku iho me te kore e aroturukitia i te wā tūturu, ka waiho pea ngā kongakonga polymer kāore anō kia nakunaku, ka whakaiti i te hanga CBM me te whai huatanga.
6. He aha te pānga o te pakaru o te CO₂ ki te matotoru o te wai pakaru i roto i ngā mahi methane o te moenga waro?
Mā te pakaru o te CO₂ ka whakaurua te CO₂ hei pahuka, hei wai tino whakamīharo rānei ki roto i te ranunga wai pakaru. Ka whakarerekētia e tēnei ngā taunekeneke matū me ngā āhuatanga rheological o te gel, ka puta:
- Ka tere te heke o te matotoru me te nui ake o te wāhanga rōrahi CO₂, te tere kutikuti, me te pāmahana
- Te tūponotanga o te pakaru o te matrix mēnā ka tere rawa te heke o te matotoru, ka mau tonu rānei ngā toenga
- Te hiahia mō ngā whakamātotoru CO₂ me ngā matū horoi motuhake hei whakau i te matotoru mō te kawe whai hua o te proppant me te pakaru pai o te gel.
Me whakamahi ngā kaiwhakahaere i te aroturukitanga matotoru wā-tūturu hei whakarerekē i te horopeta pakaru hei urupare ki ēnei āhuatanga, kia tino pakaru ai te ira me te tiaki i te hononga waro.
