Te Hydroxyethyl Cellulose i roto i te Wai Pakaru i te Keri Hinu

I ētahi wā ka whakamahia te Hydroxyethyl cellulose (HEC) i roto i te wai pakaru e whakamahia ana i roto i ngā mahi keri hinu, inā koa i roto i te pakaru waipēhi, e mōhiotia whānuitia ana ko te fracking. Ka werohia ngā wai pakaru ki roto i te puna i te pēhanga teitei hei hanga pakaru i roto i ngā hanganga toka, ka taea ai te tango i te hinu me te hau. Anei te whakamahinga o te HEC i roto i ngā wai pakaru:

1. Te Whakarerekētanga o te Matatini: He whakarerekētanga rheology te mahi a te HEC, e āwhina ana ki te whakahaere i te matatini o te wai pakaru. Mā te whakarerekē i te kukū o te HEC, ka taea e ngā kaiwhakahaere te whakarite i te matatini kia tutuki ai ngā āhuatanga wai pakaru e hiahiatia ana, kia pai ai te kawe wai me te waihanga pakaru.
2. Te Whakahaere i te Ngaronga Wai: Ka āwhina te HEC ki te whakahaere i te ngaronga wai ki roto i te hanganga i te wā e pakaru ana te wai. Ka hangaia he keke tātari angiangi, ātete ki te uru ki ngā pakitara pakaru, ka whakaiti i te ngaronga wai me te ārai i te kino o te hanganga. Ka āwhina tēnei ki te pupuri i te pumau o te pakaru me te whakarite i te mahi pai o te puna wai.
3. Whakatārewatanga Whakapūmau: He maha ngā wā kei roto i ngā wai pakaru ngā whakapūmau, pērā i te onepu, i ngā matūriki uku rānei, e haria ana ki roto i ngā pakaru kia noho tuwhera tonu ai. Ka āwhina a HEC ki te whakatārewa i ēnei whakapūmau ki roto i te wai, kia kore ai e tau, kia rite hoki te tohatoha ki roto i ngā pakaru.
4. Te Horoi Pakaru: Whai muri i te tukanga pakaru, ka taea e te HEC te āwhina ki te horoi i te wai pakaru mai i te poka wai me te whatunga pakaru. Mā ōna āhuatanga matotoru me te whakahaere i te ngaronga wai ka taea te tango pai mai i te wai pakaru mai i te puna, kia taea ai te tīmata te whakaputa hinu me te hau.
5. Hototahi ki ngā Tāpiri: He hototahi te HEC ki ngā tāpiri maha e whakamahia whānuitia ana i roto i ngā wai pakaru, tae atu ki ngā matū koiora, ngā aukati waikura, me ngā whakaiti waku. Mā tōna hototahi ka taea te hanga wai pakaru ritenga kua whakaritea ki ngā āhuatanga poka me ngā whakaritenga whakaputa.
6. Te Pūmautanga o te Pāmahana: He pai te pumau o te HEC i roto i te pāmahana, ā, he pai mō te whakamahi i roto i ngā wai pakaru e pāngia ana e ngā pāmahana teitei i raro i te poka. Ka mau tonu ōna āhuatanga rheological me tōna whai huatanga hei tāpiri wai i raro i ngā āhuatanga tino kino, kia mau tonu ai te mahi i roto i ngā mahi pakaru waipēhi.

Ka taea e te Hydroxyethyl cellulose (HEC) te whai wāhi nui ki te hanganga o ngā wai pakaru mō ngā mahi keri hinu. Ko tōna whakarerekētanga matotoru, te whakahaere i te ngaronga wai, te whakatārewatanga proppant, te hototahitanga ki ngā tāpiringa, te pumau pāmahana, me ētahi atu āhuatanga ka whai wāhi ki te whai huatanga me te angitu o ngā mahi pakaru waipēhi. Heoi, he mea nui kia whakaarohia ngā āhuatanga motuhake o te puna wai me ngā āhuatanga o te puna i te wā e hoahoa ana i ngā hanganga wai pakaru kei roto he HEC.
