Ungawakhetha Kanjani Amabhithi E-Tricone Drill

Ngokusho kwe-lithology yokubunjwa okubhoboziwe, lezi zimiso ezilandelayo kufanele zilandelwe lapho kukhethwa uhlobo lwe-drill bit:

a. Engxenyeni yomthombo ongajulile lapho idwala lifakwe usimende futhi likhululekile, ijubane lokumba le-drill bit kanye nokuvimbela amaphakethe odaka kufanele kucatshangelwe;

b. Esigabeni somthombo ojulile lapho uhambo lude, izithombe ze-drill bit kufanele zicatshangelwe;

c. Lapho amazinyo omugqa wangaphandle we-drill bit aphuma emthonjeni egugile kakhulu, kufanele kusetshenziswe kancane amazinyo okulinganisa;

d. Esigabeni somthombo ochezuka kalula, kufanele kusetshenziswe ingcosana ene-slip encane namazinyo amaningi amafushane;

e. Ukubhoboza amazinyo okumise okwe-Wedge kufanele kusetshenziswe lapho kukhethwa imishini yokufaka;

f. Nge-limestone yedayimane, kuhle ukusebenzisa izinsimbi zokubhoboza izinyo ezinama-double-cone kanye ne-projectile;

g. Uma kune-shale eyengeziwe ekubunjweni noma ukuminyana koketshezi lokumba kuphezulu, kancane ngenani elikhulu lokushelela kufanele kukhethwe;

h. Lapho i-stratum i-limestone noma i-sandstone, futhi kancane ngenani elincane lokushelela kufanele kukhethwe;

i. Uma umba i-stratum eqinile ne-abrasive kakhulu, kuyalulekwa ukuthi usebenzise inkinobho yokugoqa kanye ne-double bevel bit.

Ukuze kuthuthukiswe imingcele ye-hydraulic ye-bit, umlomo wombhobho omude kanye nobubanzi obungalingani bebhithi yombhobho ehlanganisiwe kufanele kunconywe.
