Kudhirowa nzira yekudhirowa mugomba rakadzika kuchera uye matambudziko anoda kutariswa mukushanda
tinonzwisisa kukosha kwemaitiro ekuchera uye matanho ekushanda mukuchera kwakadzika-gomba. Maumbirwo akasiyana e geological ane hunhu hwakasiyana, saka mabasa ekuchera anofanirwa kuitwa zvinoenderana nemaitiro echibhorani.
Pakuchera kuburikidza nenzvimbo dzakakanganiswa,kudonha, kupatsanurwa, uye kuumbwa kwemaumbirwo kunogona kutungamirira kuzvinhu zvakasiyana-siyana zvakadai sehuwandu hwekuyerera kwemazinga, maduku maduku, uye kurasikirwa kukuru kwepombi, zvichiita kuti zvivhare kufambira mberi kwekuchera. Pamusoro pezvo, kune njodzi dzekurasika kana kuputsika panguva yekubvisa uye kuiswa kweyakanyanya-yakadzika casings.
Kugadzirisa matambudziko aya,takaita matanho akati wandei panguva yekuchera chaiko. Chekutanga, isu tinosarudza madhiri akakura dhayamita uye tinoshandisa maturusi ekugadzirisa zvakare kuti tiwedzere kuchera uye kugadzikana. Munguva yese yekuchera, tinoramba tichigadzirisa mashandiro emvura yekugezesa uye kugezesa akawanda kuchengetedza kuchena kwechibhorani. Uyezve, kuyerwa kwehuremu kunoitwa pamberi uye mushure mekuchera kwega kwega kudzivirira kukanganisa panguva yekuregedzerwa kana kutadza zvishoma, uye kuyerwa kwakaringana kwehurefu hwakasara pane rig inotorwa kuve nechokwadi chechokwadi chenzvimbo.
Uyezve, tinoramba takangwarira kupomba kwepombi, kudzoka kwemvura, ruzha rusina kujairika, uye shanduko yemagetsi mukati megomba kuderedza njodzi dzekutsva kana kupaza chibhorani. Tichifunga kukosha kwekupokana mukuchera kwakadzika-gomba, tinoshandisa nzira dzekusimudza chibhorani kubva pasi pechibhorani, zvishoma nezvishoma tinobata clutch kana kumhanya kwekutenderera kwasvika padanho rakatarwa, tozoenderera mberi zvishoma nezvishoma nekuchera kwakajairika kudzivirira kamwe kamwe torque inowedzera iyo. zvinogona kutungamira mukutsemuka kwetsvimbo.
Mukupedzisa, kushandiswa kwekuchera pasi-the-hole (DTH) mabheti kwakavandudza zvakanyanya kuchera uye kuderedza mari yepurojekiti mumapurojekiti ekuchera kwakadzika-gomba, zvichibatsira zvakanyanya mukutsvagisa simba nemamineral. Isu takazvipira kuenderera mberi nekugonesa maitiro edu ekuchera, kuwedzera mashandiro ekushanda, uye kuendesa zvigadzirwa zvakavimbika uye zvinoshanda nemasevhisi kune vatengi vedu.
