Yuav Ua Li Cas Xaiv Txoj Cai Drill Bits rau Cov Qauv Sib Txawv?

Feem ntau, cov av tuaj yeem faib ua mos, nruab nrab, lossis tawv. Cov hauv av mos feem ntau muaj cov ntaub ntawv xws li av nplaum thiab mos limestone. Qhov nruab nrab hauv av, ntawm qhov tod tes, yuav muaj cov tawv shale thiab dolomite-hom khoom. Thiab thaum kawg, cov av tawv feem ntau muaj cov khoom siv pob zeb zoo li granite.

Xaiv qhov zoo ntawm cov laum me ntsis yuav pab tau kom muaj txiaj ntsig zoo thiab muaj txiaj ntsig zoo drilling txheej txheem.

1. Drill Bits rau qhov chaw mos hauv av

Drag me ntsis los yog cov khoom siv tas li yog qhov zoo tagnrho rau cov haujlwm uas muaj feem ntau hauv av. Cov laum khoom no yog tsim los ntawm ib qho ntawm cov khoom hlau. Txawm hais tias carbide inserts yuav siv tau, lawv tsis yog qhov tsim nyog. Cov laum cov khoom no tsis muaj qhov dov lossis cov kabmob sib txuas. Yog li ntawd, tag nrho cov kev sib dhos txiav tig nrog txoj hlua laum thiab txiav hauv av thaum cov hniav tig.

Qhov tsis muaj bearings thiab dov Cheebtsam txhais tau tias tsawg dua cov pob qij txha txav, thiab yog li, tsawg dua kev puas tsuaj rau lub rooj sib dhos.

2. Drill Bits rau nruab nrab thiab nyuaj hauv av

(1) Peb-cone dov cutter me ntsis nrog Tungsten Carbide Inserts

(2) polycrystalline pob zeb diamond compact me ntsis

Txhawm rau nkag mus rau cov av denser, cov khoom yuav tsum muaj lub zog txaus thiab kav ntev kom ua tiav cov khoom tawg thiab txav nws tawm ntawm txoj kev. Ib hom kev xyaum me me rau drilling hauv nruab nrab mus rau hauv av nyuaj yog peb-cone dov cutter me ntsis thiab polycrystalline pob zeb diamond compact me ntsis.

Peb-cone dov cutter me ntsis muaj peb rotating cones nrog lawv cov ntsiab lus tig mus rau sab hauv ntawm qhov chaw. Lub cones tig thiab zom cov av / pob zeb thaum lub laum txoj hlua ib txhij tig tag nrho me ntsis.

Kev xaiv cov khoom siv ntxig yog nyob ntawm qhov hardness ntawm cov av uas yuav tsum tau nkag mus. Carbide inserts yog qhov zoo tshaj plaws rau nruab nrab hauv av, thaum cov pob zeb diamond polycrystalline feem ntau yog siv rau cov pob zeb.

Rau cov xwm txheej hnyav, cov khoom siv polycrystalline pob zeb diamond compact (PDC) tuaj yeem ua haujlwm. Synthetic diamonds yog txuas nrog cov carbide inserts los muab cov cuab yeej laum lub zog txog li 50 npaug ntau dua li cov khoom siv hlau. PDC laum khoom siv rau hauv av nyuaj heev, zoo li cov pob zeb tsim.

Kev txiav txim siab qhov zoo ntawm cov laum me ntsis feem ntau yuav tsum muaj kev tshawb nrhiav geological, cov ntaub ntawv qhia txog geological, thiab nruj me ntsis raws li cov ntaub ntawv muab los ntawm geologists thiab geotechnical engineering cov kws tshaj lij.

Hauv ZZBETTER, peb muab PDC cutter rau PDC laum me ntsis, txhawm rau ua kom koj cov txiaj ntsig tau zoo tshaj plaws thiab txhim kho koj qhov kev paub drilling tag nrho. Yog tias koj txaus siab rau PDC laum cov khoom thiab xav tau cov ntaub ntawv thiab cov ntsiab lus ntxiv, koj tuaj yeem tiv tauj peb hauv xov tooj lossis xa ntawv ntawm sab laug, lossis xa US MAIL hauv qab ntawm nplooj ntawv.
