Ukukhethwa kwezesekeli zokubhoboza ezijikelezayo

Kunezinhlobo eziningi ze-izesekeli zokubhoboza ezijikelezayoIzesekeli ezahlukene zokubhoboza ezijikelezayo kufanele zikhethwe ezindaweni ezahlukene zokwakha kanye nezigaba ezahlukene.

a. I-slag yokudoba kanye nebhakede lesihlabathi kufanele kusetshenziswe ukudoba i-slag;

b. I-barrel bit kufanele isetshenziswe kuma-stratum edwala anamandla aphansi;

c. Uma kusetshenziswa i-conical spiral bit, i-coring bit ekhethekile kumele isetshenziswe ekuthatheni isampula eyinhloko;

d. Ibhakede lokubhoboza elijikelezayo kufanele lisetshenziswe njengengqimba yomhlabathi;

e. Uma kukhona inqwaba yensimbi, i-belled bit kufanele isetshenziswe engxenyeni yensimbi;

f. Uma i-stratum yedwala enamandla aphezulu iwela futhi ibhakede lokubhoboza elijikelezayo lingakwazi ukuqhubeka nokubhoboza, kufanele kusetshenziswe i-cone screw bit;

Ukukhethwa kwezesekeli zokubhoboza ezijikelezayo kuzothinta ukusebenza kahle kokwakha. Uma izesekeli zokubhoboza zikhethwe kahle, ukusebenza kahle kokwakhiwa kwe-rotary drilling rig kuzothuthukiswa kakhulu.
