Wheketere API o te mata keri toka tricone hau maori

Ngā mata keri toka tricone hinu API rarawe me te peera hiri mata whakarewa mai i te wheketere Haina.
Whakaahuatanga Moka:
IADC: 417-TCI mata pere hiri-hautaka me te tiaki ine mō ngā hanganga ngohengohe me te kaha pēhi iti me te kaha keri teitei.
Kaha Whakapūmau:
65-85 MPA
9,000-12,000 PSI
Whakaahuatanga Whenua:
He roa ngā mokowā o ngā kirikiri ngohengohe rawa, ngā toromite, ngā kirikiri onepū, ngā uku, ngā tote me ngā kohatu kōhatu, kāore i te tino kiato.
Ka taea e mātou te tuku atu i ngā mata TCI me ngā mata niho maitai i roto i ngā rahi rerekē (mai i te 3" ki te 26") mete nuinga o ngā waehere IADC.
Ko ngā whenua nui o te ao e keri ana i te hau māori ko te Hononga o Amerika, Rūhia, Turkmenistan, Īrāna, Qatar, Algeria, Netherlands me ērā atu. Kua tīmata hoki a Haina ki te whakaputa hau shale i ngā tau tata nei. Ko tētahi o ngā whakamahinga matua o te hau shale ko ngā konganuku hiri-whakairo e mau ana i ngā mata tricone.
Pērā i te hinu, ka tanumia te hau māori ki roto i ngā hanganga whenua kua kati, ko ētahi kei roto i te paparanga kotahi me te hinu, ko ētahi kei waho.
Ka tangohia tahitia te hau maori e rongoa ana i te rohe kotahi me te hinu mata.
Nā te uaua o ngā āhuatanga whenua o te keri poka hohonu o te hau māori, ko ngā raruraru whenua hangarau kāore e kitea i mua ka arahi ki te rerekētanga i waenga i te keri me te hoahoa tuturu, ā, ka arahi ki ngā raruraru keri nui me ngā aituā, e kore e whakararu noa i te haumaru me te whakatutukitanga o ngā whāinga whenua, engari ka tino whakawhāiti hoki i te tere o te keri me te whakanui ake i ngā utu keri.
