I-API yomzi-mveliso we-oyile kakuhle i-tricone yokomba amasuntswana okwakhiwa kwamatye anzima

Ungazikhetha njani iiBits zeTricone Drill

Ngokutsho kwe-lithology yokwakheka kwe-drilled, le migaqo ilandelayo kufuneka ilandelwe xa ukhetha uhlobo lwe-drill bit:

a. Kwicandelo lomthombo ongekho nzulu apho ilitye lenziwe ngesamente kwaye likhululekile, isantya sokugaya i-drill bit kunye nokuthintela iipakethi zodaka kufuneka ziqwalaselwe;

b. Kwicandelo lequla elinzulu apho uhambo lude, imifanekiso ye-drill bit kufuneka ithathelwe ingqalelo;

c. Xa amazinyo omqolo wangaphandle we-drill bit ephuma emthonjeni agqitywe kakhulu, kufuneka kusetyenziswe intwana enamazinyo okulinganisa;

d. Kwicandelo lokuphambuka elilula, kufuneka kusetyenziswe isiliphu esincinci kunye namazinyo amaninzi amafutshane;

e. Ukukrola amazinyo okwe-wedge kufuneka kusetyenziswe xa ukhetha ukufaka izixhobo;

f. Kwi-limestone yedayimane, kuyacetyiswa ukuba usebenzise i-double-cone-tooth kunye ne-projectile-shaped drill bits drill;

g. Xa kukho i-shale eninzi ekubunjweni okanye ubuninzi be-drilling fluid buphezulu, i-bit kunye ne-slip isixa esikhulu kufuneka ikhethwe;

h. Xa i-stratum i-limestone okanye i-sandstone, kunye ne-bit kunye nexabiso elincinci le-slip kufuneka likhethwe;

i. Xa usomba istratum esiqinileyo kunye ne-abrasive kakhulu, kuyacetyiswa ukuba usebenzise iqhosha elicocekileyo lokuqengqeleka kunye ne-bevel bit.

Ukuze kunyuswe iiparamitha ze-hydraulic zebit, umbhobho omde kunye nedayamitha engalinganiyo edityanisiweyo yebit yomlomo kufuneka ikhethwe.
