Izingcezu zokubhoboza i-tricone emthonjeni wamafutha efektri ye-API zokwakheka kwamadwala aqinile

Indlela Yokukhetha Ama-Tricone Drill Bits

Ngokusho kwe-lithology yokwakheka okubholiwe, izimiso ezilandelayo kufanele zilandelwe lapho kukhethwa uhlobo lwe-drill bit:

a. Engxenyeni yomthombo ongajulile lapho idwala lifakwe khona usimende futhi likhululekile, isivinini sokubhoboza se-drill bit kanye nokuvimbela amaphakethe odaka kufanele kucatshangelwe;

b. Engxenyeni yomthombo ojulile lapho uhambo lude khona, kufanele kucatshangelwe izithombe zengxenye yokubhoboza;

c. Uma amazinyo omugqa wangaphandle wengxenye yokubhoboza ephuma emgodini egugile kakhulu, kufanele kusetshenziswe ingxenye enamazinyo okulinganisa;

d. Esigabeni somthombo esiphambuka kalula, kufanele kusetshenziswe ingxenye encane enokushelela okuncane namazinyo amaningi amafushane;

e. Ama-drill amazinyo amise okwe-wedge kufanele asetshenziswe lapho kukhethwa ama-drill okufaka;

f. Nge-limestone yedayimane, kuyalulekwa ukusebenzisa izinti zokubhoboza izinyo ezinamakhoni amabili kanye nezimbobo ezimise okwe-projectile;

g. Uma kukhona i-shale eningi ekwakhekeni noma ubuningi boketshezi lokubhoboza buphakeme, kufanele kukhethwe okuncane okunenani elikhulu lokushelela;

h. Uma i-stratum iyi-limestone noma i-sandstone, futhi ingxenye encane enenani elincane lokushelela kufanele ikhethwe;

i. Uma ubhoboza i-stratum eqinile futhi ekhahla kakhulu, kuyalulekwa ukusebenzisa inkinobho yokugoqa emsulwa kanye ne-double bevel bit.

Ukuze kwenziwe ngcono amapharamitha e-hydraulic e-bit, kufanele kukhethwe i-nozzle ende kanye ne-nozzle bit ehlanganisiwe enobubanzi obungalingani.
