I. Kutangwa kwetekinoroji isina kuchera
Tekinoroji isina kuchera imhando yetekinoroji yekuvaka yekuisa, kugadzirisa, kutsiva kana kuona mapaipi epasi pevhu netambo nenzira yekuchera zvishoma kana kusachera. Kuvaka kusina kuchera kunoshandisa musimboti wekuchera nedivitekinoroji, inoderedza zvakanyanya rudo rwekuvakwa kwemapaipi epasi pevhu kune mota, nharaunda, zvivakwa, pekugara nekushanda kwevagari, inova chikamu chakakosha muguta razvino chekuvaka nekutarisira tekinoroji.
Kuvaka kusina migero kwakatanga kubva kuma1890 uye kwakakura ndokuva indasitiri muma1980 munyika dzakabudirira. Kwave kuchikura nekukurumidza mumakore makumi maviri apfuura, uye parizvino kwave kushandiswa zvakanyanya mumapurojekiti akawanda ekuvaka mapaipi nekugadzirisa mumaindasitiri akawanda akadai sepeturu, gasi rechisikigo, mvura, magetsi, kutaurirana nefoni uye kupisa nezvimwewo.

II. Nheyo yekushanda uye matanho ekuvaka chidhiraivho cheDrill chakatambanudzwa
1. Kusunda chibato chebooresa netsvimbo yekubooresa
Mushure mekugadziriswa kwemuchina, zvichienderana nekona yakatarwa, chidhiraivho chinotyaira tsvimbo yekudhiraivha ichitenderera mberi nesimba remusoro wesimba, uye chinosundirwa zvichienderana nekudzika nekureba kunodiwa kwepurojekiti, kuyambuka zvipingamupinyi wobva wasvika pamusoro pevhu, uchidzorwa nemuridzi wenzvimbo. Munguva yekusundirwa, kuitira kudzivirira tsvimbo yekudhiraivha kuti isabatike nekukiya nevhu, inofanira kugadzira simende yakazvimba kana bentonite nepombi yematope kuburikidza netsvimbo yekudhiraivha netsvimbo yekudhiraivha, uye panguva imwe chete kusimbisa nzira uye kudzivirira gomba kuti risapinde mukati.
2. Kudzokorora ne reamer
Mushure mekunge chidhiraivho chaburitsa tsvimbo yekuboorera pasi, bvisa chidhiraivho wobatanidza reamer netsvimbo yekuboorera woigadzirisa, wodhonza musoro wemagetsi, tsvimbo yekuboorera inotungamira reamer kudzokera kumashure, wowedzera saizi yegomba. Zvichienderana nedhayamita yepombi nekusiyana-siyana, kushandura saizi yakasiyana yereamer neream kamwe chete kana kupfuura kusvika yasvika dhayamita yegomba rinodiwa.
3. Dhonza pombi kumashure
Kana wasvika padhayamita yegomba rinodiwa uye reamer ichizodhonzwa kekupedzisira, gadzirisa pombi kune reamer, musoro wemagetsi uchadhonza tsvimbo yekuboorera woita kuti reamer nepombi zvidzokere kumashure, kusvika pombi yadhonzwa pasi, basa rekuisa pombi rapera.
