89mm yekuchera pombi yekuchera tsime remvura ine API IF shinda
Iyi pombi yemvura yekuboorera yemvura, iyo yakapfupikiswa yepasi pegomba pombi yekuboorera, imhando yekunze kwetsvimbo yekuboorera.Inonyanya kushandiswa muku rotary percussive drilling ine magasi uye zvinwiwa.Zvikamu zvaro zvikuru zvinosanganisira pombi (tsvimbo) muviri uye majoini.
Yedu pasi pegomba drill pombi inogadzirwa zvichienderana neiyo API zviyero.Uye zvinoenderana nezvinodiwa chaizvo, isu tinopawo rudzi urwu rweDTH drill pombi mune akasiyana maChinese neAmerica maratidziro.
Kana zviri zvakanakira kwayo, ine zvimiro zvekusimba kwakakura, yakanaka yekuisa chisimbiso, yakadzika yekunze chimiro, uye yakaderera torque uye kuramba kana ichitenderera.
Nezvekurongedzerwa, bundle remapombi ekuboorera eDTH anozorongedzerwa neseti imwe chete yesimbi, uye bundle rinenge riine 30 kusvika 40 mapaipi ekuboorera.
