Yuav Ua Li Cas Xaiv Tricone Drill Bits

Raws li lub lithology ntawm kev xyaum tsim, cov hauv qab no yuav tsum tau ua raws li cov hauv qab no thaum xaiv hom laum ntsis:

a.Nyob rau hauv lub qhov dej ntiav nyob qhov twg cov pob zeb yog cemented thiab xoob, qhov drilling ceev ntawm lub laum me ntsis thiab kev tiv thaiv cov av nkos yuav tsum tau txiav txim siab;

b.Nyob rau hauv qhov tob qhov dej qhov twg qhov kev mus ncig yog ntev, cov duab ntawm lub laum me ntsis yuav tsum tau xav txog;

c.Thaum cov hniav sab nrauv ntawm lub laum me ntsis tawm ntawm lub qhov dej yog hnyav hnyav, me ntsis nrog ntsuas cov hniav yuav tsum tau siv;

d.Nyob rau hauv qhov yooj yim deviating zoo seem, me ntsis nrog me me plam thiab ntau cov hniav luv yuav tsum tau siv;

e.Wedge-shaped tooth drills yuav tsum tau siv thaum xaiv cov khoom siv tho;

f.Rau pob zeb diamond limestone, nws raug nquahu kom siv ob-cone-tooth thiab projectile-zoo li tus hniav laum khoom;

g.Thaum muaj ntau shale nyob rau hauv lub tsim los yog qhov ceev ntawm drilling kua ntau dua, me ntsis nrog ib tug loj dua tus nqi yuav tsum tau xaiv;

h.Thaum lub stratum yog limestone los yog sandstone, thiab ib tug me ntsis nrog ib tug me me nplawm nqi yuav tsum tau xaiv;

i.Thaum drilling nyuaj thiab abrasive heev stratum, nws yog advisable siv ntshiab dov khawm thiab ob chav bevel me ntsis.

Txhawm rau ua kom zoo dua qhov ntsuas hydraulic ntawm me ntsis, qhov ntev ntawm lub nozzle thiab txoj kab uas hla tsis sib xws ua ke nozzle me ntsis yuav tsum nyiam dua.
