Kuchera uye kudonha kwegomba ndiwo matambudziko akajairika uye anonetsa mumapurojekiti mazhinji akaomarara ekuchera geological.Zvakaoma kuvimbisa kunaka uye kugona kwekuchera neyakajairwa drilling tekinoroji.
Zvisinei, kuonekwa kwepombi inotevera kunogadzirisa zvakakwana dambudziko iri.Inodzivirira madziro echibhorani nekaseji uku ichiboora zvakanaka, uye inodzoreredza kubhenda kwechibhorani nekuomarara kunotungamira kwekaseji.Parizvino, eccentric uye concentric pombi yekuchera maturusi anoshandiswa zvakanyanya muChina.Nekuda kwekusimba kwemadziro ekunze bhiti, simba rekufambisa mhedzisiro ye concentric drilling tool haina kunaka seye eccentric drilling tool yeimwe aperture kuvaka.Chete kana dhayamita yemudziyo wekuchera yakakura uye iyo impactor ine high wind pressure inosarudzwa, mhedzisiro yacho iri nani, asi mutengo wekugadzira wakakwira zvakanyanya kupfuura iwo eccentric drilling tool.Eccentric pombi yekuchera chishandiso haina kungoita gomba rakakura dhayamita, asi zvakare ine chimiro chakareruka, yakaderera mutengo wekugadzira uye nyore kushandisa, saka yakashandiswa zvakanyanya.
Nheyo yekushanda ye eccentric bit ndeye:
1, iyo DTH nyundo eccentric ine pombi yekuchera sisitimu, chero eccentric ine pombi yekuchera maturusi ane chubhu kana chibhorani chakacherwa ne eccentric chakakura kupfuura casing dhayamita gomba, uye kana kuchera kune yakafanotemerwa pasi, convergence, uye pombi yekuchera maturusi. inogona kugadzirwa neiyo yakakura yekunze dhayamita yepombi yekuboorera chishandiso isingasviki mukati dhayamita yechubhu bhutsu, casing, kubvisa nepombi yekuchera maturusi, casing inogona kuramba iri mukugadzira inodzivirira gomba madziro.
2. Paunenge uchichera kazhinji, mhepo yakamanikidzwa inopiwa nemhepo compressor inopinda muDTH impactor kuburikidza ne drill uye drill pipe kuti iite kushanda.Iyo piston ye impactor inokanganisa iyo normalizer yechishandiso chekuchera nechubhu, uye normalizer inotamisa shock wave uye bit pressure kune eccentric bit uye nechepakati bit kutyora dombo pazasi pegomba.
3. Kana hukuru hwechigadziro huri hukuru kudarika kupesana kwekugadzirisa kwekuumbwa kumadziro evhavha, casing ichatevera nehuremu hwayo.
4. Gomba rakaputirwa ne-eccentric bit yakakura kudarika yakawanda yekunze kwekunze kwekasi, kuitira kuti ganda rirege kudziviswa nedombo riri pasi pegomba uye rinotevera.
