Chibhorani (drilling rig) igadziriro yakasanganiswa inochera matsime, semafuta emafuta kana gasi, pasi pevhu.
Mashizha ekuchera anogona kunge ari mahombe edzimba anoshandiswa kuchera matsime eoiri, kana matsime ekuchera gasi, madhiri ekuchera anogona kuenzanisa madhipoziti epasi pevhu, dombo rekuyedza, ivhu uye mvura yepasi zvivakwa, uye zvakare inogona kushandiswa kuisa pasi pepasi pevhu, senge. sezvishandiso zvepasi pevhu, 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 zvemamita epasi, vachishandisa "mapombi ematope" makuru kutenderedza madhaka ekuchera (slurry) kuburikidza nebhiti rekuchera uye kumusoro kwecasing annulus, yekutonhodza nekubvisa "cuts" apo tsime riripo. drilled.
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.
