Chibhorani (drilling rig) igadziriro yakasanganiswa inochera matsime, semafuta emafuta kana gasi, pasi pevhu.
Midziyo yekuchera inogona kunge yakakura zvivakwa zvedzimba zvinoshandiswa kuchera matsime eoiri, kana matsime ekuchera gasi echisikigo, madhiri ekuchera anogona kuenzanisa subsurface mineral deposits, test rock, ivhu uye pasi pevhu zvimiro zvemuviri, uye zvakare inogona kushandiswa kuisa pasi pepasi pevhu, senge pasi pevhu zvinoshandiswa, zviridzwa, tunnels kana matsime. Midziyo yekuchera inogona kunge iri midziyo inotakurwa pamarori, njanji kana matrailer, kana zvimwe zvimiro zvechigarire kana zvivakwa zvemugungwa (senge mapuratifomu emafuta, anowanzonzi 'offshore oil rigs' kunyangwe asina chekuchera).
Madiki kusvika epakati nepakati madhirigi anofambisa, seaya anoshandiswa mukuchera zvicherwa, kuputika-gomba, matsime emvura uye kuongorora kwezvakatipoteredza. Midziyo mikuru inokwanisa kuboora zviuru nezviuru zvemamita epasi, vachishandisa “mapombi ematope” mahombe ekutenderedza madhaka ekuchera (slurry) kuburikidza nechibhorani uye kukwidza casing annulus, kutonhodza nekubvisa ma “cuttings” apo tsime richiboorwa.
Hoists mune rig inogona kusimudza mazana ematani epombi. Mimwe midziyo inogona kumanikidza asidhi kana jecha kuti ripinde mumadhamu kuitira kufambisa kutorwa kweoiri kana gasi rechisikigo; uye munzvimbo dziri kure panogona kuva nepekugara zvechigarire uye zvokudya zvevashandi (zvingangove zvinopfuura zana).
Offshore rigs anogona kushanda zviuru zvemamaira kure kubva pabhesi rekushandisa nekusawanzotenderera kwevashandi kutenderera kana kutenderera.
Tinogona kugovera madhiri ekuchera kubva pa500-9000 metres kudzika, zvese zvichifambiswa netafura inotenderera uye yepamusoro dhiraivha system, Kusanganisira iyo skid yakaiswa rig, track yakaiswa rig, workover rig uye offshore rig.
