Yuav xaiv ADC me ntse li cas?

1. Pob zeb hardness: ib qho kev sib tw ntawm kev nyuaj thiab yooj

CENTER QHIA: Muaj peev xwm ntawm pob zeb kom tiv thaiv cov khoom tawg lossis khawb.

Cov kev sib tw hauv cov pob zeb nyuaj (xws li granite, basalt): siab hardness yooj yim ua rau chipping ntawm cov hniav thiab hnyav hnav ntawm laum me ntsis. Cov yam ntxwv ntawm Laum Uas Tsim Nyog:

High-extive txiav cov hniav: zoo-zooPdc cutterNrog rau kev cuam tshuam zoo heev thiab zoo thermal kev ruaj khov yuav tsum tau xaiv.

Thick hniav qauv: txhim kho lub zog qauv ntawm cov hniav lub cev tiv thaiv kev tiv thaiv lub pob zeb.

Kev txiav me me: Ntau yam tsis zoo rau -15 ° rau -25 °) feem ntau saws, feem ntau yog rau kev pheej hmoo ntawm brittle benacture thiab txhim kho kev nkag mus.

Txhawb nqa gauge tiv thaiv qauv: tiv thaiv covlaum me ntsisTxoj kab uas hla los ntawm kev txo qis sai vim muaj kev hnav hnyav.

2. Pob zeb abroriveness: qhov kawg xeem tau ntawm kev ruaj khov

Core qhia: muaj peev xwm ntawm pob zeb los hnav cov hniav txiav thiab covlaum me ntsislub cev (ze ze rau cov ntsiab lus ntawm cov zaub mov nyuaj xws li Quartz).

Cov ntawv sau Abrasive pob zeb (xws li Quartz Sandstone, ntxhib-grained granite, chert txheej):

Cov yam ntxwv ntawm HaumLaum Cov Khaub Ncaws:

Ultra-hnav-resistant txiav cov hniav: Siv cov txheej PDC nrog ntau dua thermal ruaj khov thiab muaj zog hnav coj tsis kam.

Kev npaj hniav tuab tuab: Nce tus naj npawb ntawm cov hniav txiav kom sib qhia cov hnav ris ntawm ib tus hniav.

Cov qauv zoo tshaj plaws Hydraulic: kom cov kev tshem tawm ntawm kev txiav tawm kom tsis txhob hnav kom nrawm dua vim muaj kev sib tsoo ob sab.

Txhawb kev tiv thaiv kev tiv thaiv / kev cais-tiv taus: Hardfacing carbide lossis inlay cov chaw tiv thaiv lub xub pwg thiab ntsuas kev tiv thaiv.

3. Tus qauv tsim qauv thiab homogeneity: kev yoog raws kev tsim qauv

Cov kev txiav txim siab tseem ceeb: kev txhim kho ntawm lub txaj, pob qij txha, pob qij txha hauv cov pob zeb tsim, thiab cov teeb meem ntawm kev hloov pauv nyuaj thiab cov khoom muag muag.

Cov kev tsim qauv nyuaj (xws li kev txhaum pob zeb, shale nrog cov pob qij txha, sandstone-mudstone interbeds):

Cov yam ntxwv ntawm HaumLaum Cov Khaub Ncaws:

Siab cuam tshuam: txiav cov hniav thiablaum me ntsisLub cev yuav tsum muaj peev xwm tiv thaiv kev cuam tshuam kev cuam tshuam los ntawm kev hloov pauv sai heev hauv kev tsim.

Ruaj khov tsim: zoo quab yuam sib npaug tsim qauv (tsis tshua muaj zog hloov pauv) thiab goosge tiv thaiv tus qauv los tiv thaiv kev co lossis deflection ntawmlaum me ntsisNyob rau hauv bacture aav lossis muag txheej.

FLEXIBLE TXIAV TXIM: MUAB TXHAWB COODER SILE LOSSIS sib txawv

4. Drilling cov lus: Cov theem rau kev ua tau zoo

Cov tub ntxhais txuam: tus qauv tsim ntawm lublaum me ntsisXav tau kom phim qhov kev cia siab ntawm qhov hnyav ntawm ntsis (WOB) thiab kev sib hloov ceev (RPM).

Cov Ntsiab Lus Tseem Ceeb:

Siab wob / qis rpm: feem ntau haum rau kev ua haujlwm nyuaj, xav tau covlaum me ntsiskom muaj cov qauv muaj zog dua (xws li tuab tuab) thiab lub kaum sab xis tsis zoo txiav cov hniav.

Tsawg wob / siab RPM: haum rau muag muag rau nruab nrab-nyuaj tsim, tuslaum me ntsistuaj yeem tsim nrog Shaper zoo lub kaum sab xis txiav cov hniav thiab cov qauv hydraulic zoo pab rau nti tshem tawm.

Parameter Optimization: Txawm hais tias lub laum ntsis nws tus kheej yog qhov tsim nyog txav kev cuam tshuam kev cuam tshuam) yuav ua rau kev puas tsuaj rau kev puas tsuaj rau lub laum me ntsis lossis qis ua haujlwm.

5. Hom PDC Laum Sij Hawm: Txhua tus muaj nws tshwj xeeb

Cov kev faib tawm tseem ceeb: Raws li cov qauv tsim qauv thiab kev thov cov xwm txheej, muaj cov hom phiaj tseem ceeb ntawmPdc Laum me ntsis:

Hom Qauv: Ntau yam, haum rau nruab nrab muag rau nruab nrab-nyuaj, homogeneous tsim.

Txhim Kho / Kev Cuam Tshuam-Resistrange Cov Qauv (xws li tuab tuab, ua rau muaj kev sib cav sib ceg, cov kab mob nyuaj, cov pob zeb loj los yog cov kev co.

Cov ntaub ntawv tiv thaiv Abrasive-resistant: Siv cov ris tsho tiv thaiv feem ntau, kev tiv thaiv kev tiv thaiv kev ua haujlwm zoo tshaj plaws (xws li Quartz Sandstone).

Sib sib zog nqus / ultra-tob hom: Tshwj xeeb qhia txog kev ruaj khov ntawm thermal stability thiab kev ntseeg tau nyob rau hauv qhov ntsuas kub-thiab siab siab.

Directional / kab rov tav zoo hom: optimized rau cov lus qhia, ruaj khov thiab tiv thaiv whirl muaj peev xwm.

Xaus: Qhov kev txiav txim siab ntau yam ua rau cov qauv sib piv
