Ntuj Pob Zeb Laum Laum
Tsim kom muaj ROP siab dua hauv kev sib sib zog nqus thiab sib zog ua haujlwm, PDC xyaum me ntsis ib txwm xyaum los ntawm hauv av mus rau hauv qab ncaj qha nrog tsawg lossis txawm tias ib zaug khiav, txuag ntau qhov kev siv sijhawm thiab tus nqi.
Sib txawv los ntawm tricone ntsis, PDC laum me ntsis khiav nrog WOB qis dua tab sis siab dua RPM, yog li nws feem ntau ua haujlwm nrog lub tshuab qis qis kom tuaj yeem nrawm nrawm.
Kev ua tau zoo ntawm PDC laum me ntsis nyob ntawm ntau ntawm PDC cov tshuab txiav, peb muab cov kev daws teeb meem tshwj xeeb rau qhov xav tau tshwj xeeb ntawm cov ntawv sib txawv.
Taw qhia:
Ntuj Pob Zeb Laum Laum yog qhov tsim nyog rau coring hauv nruab nrab mus rau qhov nyuaj formations nrog qee qib ntawm kev tsim cov txhuam.
Nta
1.Qhov tshwj xeeb matrix formula: Cov qauv sib txawv tshwj xeeb ua rau matrix sib phim hnav thiab tsim, ua kom zoo dua qhov txiav thiab hnav tsis kam ntawm pob zeb diamond uas ua rau me ntsis tau txais ROP zoo dua.
Tshuab
1.Radiant waterway tsim: Me ntsis muaj cov qauv dej ntws uas tsim nyog rau kev nrawm.
DeepFast lub pob zeb diamond laum me me muab cov kev nkag mus tau zoo tshaj plaws thiab kev pab lub neej nyob rau hauv cov txheej txheem mos. Cov khoom no ua haujlwm hauv cov pob zeb mos thiab nruab nrab-mos xws li limestone, sandstone, av nplaum thiab lwm yam. Nws tuaj yeem hloov kho hauv pob zeb diamond loj, pob zeb diamond zoo, matrix hardness, pob zeb diamond raug, tsim yas thiab lwm yam rau cov neeg siv khoom.
