1. Theknoloji ea ho cheka hamore le li-tube tsa thekenoloji e sebelisa ka botlalo melemo ea hamore e ka tlaase-hole ea pneumatic ho senya lejoe ka potlako, e leng se loketseng ho nts'etsopele le ts'ebetsong ea liliba tse kopantsoeng tsa lipatlisiso le tlhahiso ea hydrogeological. lipatlisiso.
2. Theknoloji ea ho cheka ka morao-rao e ka latela casing ha e ntse e phunya.Ha e hloke metsi le seretse sa ho cheka, haholo-holo libakeng tse omeletseng le tse se nang metsi.E ka etsa boiteko bo habeli ka halofo ea boiteko, ea qoba bothata ba ho reka metsi a ho cheka, le ho ntlafatsa katleho ea mosebetsi.Ho ntlafatsa ho molemo haholo.
3. Mofuta ona oa thekenoloji ea ho phunya o sebelisa synchronous late-up casing ho sireletsa lerako ha u phunya, ho sebelisa ka botlalo melemo ea moea DTH hamore ho senya lefika ka potlako, ha u ntse u boloka lerako la lesoba la letoto la bone la moroalo o fokolang. karolo e ka hodimo ya setapo sa metsi.Li-cuttings tse robehileng li etsoa ka sekoting ka ho phalla ha moea ka lebelo le phahameng, 'me phello ea ho hula e molemo ho bula mocha oa ho ntša metsi.Ho hlatsuoa ho tsoelang pele ha lebota la lesoba ka moea o lebelo le phahameng ho tla khutsufatsa nako ea ho hlatsoa liliba, e leng molemo ho ntlafatso ea ho cheka ha metsi le ho phethoa hantle ha seliba.
4. Theknoloji ea ho phunya hamore e ka tlaase-hole le liphaephe li loketse ho phunya lejoe le thata.Bakeng sa libopeho tsa letsopa kapa libopeho tse tšoanang tse bonolo, ho bonolo ho thibela tsela ea moea le li-cuttings tsa ho phunya ho bonolo ho fanyeha leboteng la sekoti ho etsa seretse sa seretse, seo ho leng thata ho se finyella katleho e nepahetseng ea ho cheka .
