Lub Ridged Pob Zeb Diamond Txiav Element

PDC cutters yog lub hauv paus txiav ntawm PDC cov khoom, thiab lawv cov kev ua tau zoo yog qhov tseem ceeb rau kev ua haujlwm ntawm PDC cov khoom. Cov tuam txhab me me txawv teb chaws tsis tau tso tseg kev tshawb fawb thiab kev tsim kho ntawm PDC cutter khoom.

Lub Ridged pob zeb diamond txiav cov khoom muaj qhov tshwj xeeb geometry uas sib xyaw ua ke ntawm cov pa PDC cutters nrog compression ntawm tungsten carbide inserts (TCI). Cov pob zeb diamond ridged tuaj yeem siv nrog cov matrix thiab steel-bodied khoom los xyaum qhov tsis zoo sib xws tsis tu ncua los ntawm txoj kab ntsug, nkhaus, thiab sab.

Lub crushing muaj nuj nqi nyob rau hauv ib tug, qhov zoo yog raws li nram no:

(1) Txhim kho kev ua tau zoo rau kev txhim kho ROP tam sim

Lub crushing thiab shearing kev txiav txim ntawm lub Ax lub caij ua tiav tsawg kawg yog 22% kev nkag mus tob kom muab siab dua ROP instantaneous siv tib qhov hnyav ntawm me ntsis thiab rpm siv rau cov pa PDC cutters. Tus yuam sij yog nyob rau hauv lub ridge-puab geometry, uas yields lub pob zeb diamond rooj uas yog 70% thicker tshaj li ib tug pa cutter thaum muab siab dua frontal cuam tshuam. Qhov no feature txhais mus rau hauv kev txhim kho durability thiab npub tej yam kev mob rau kev tswj lub siab tshaj plaws ROP thoob plaws hauv lub khiav.

(2) Txhim khu kev tswj nyob rau hauv kev taw qhia kev siv

Qhov txo txiav quab yuam yuav tsum tau los ntawm cov khoom siv laum txhais kom tsawg dua torque, txo qis reactive torque fluctuation, thiab cov cuab yeej zoo dua lub ntsej muag tswj hauv kev siv nkhaus. Qhov kom zoo dua no ua rau cov nqi tsim tau zoo dua thiab siab dua tag nrho ROPs, pab ua kom qhov chaw tsim khoom nthuav dav thiab txo lub sijhawm drilling.

Piv nrog cov pa PDC cutters, lub thickness ntawm lub pob zeb diamond txheej yog nce los ntawm 70%. Ua ke nrog cov qauv patented ntawm polycrystalline pob zeb diamond particle loj tis thiab cov khoom siv zoo, cov kev cuam tshuam pem hauv ntej tau txhim kho, thiab kev ua haujlwm ntev ntawm lub laum me ntsis yog txhim kho. Li no prolonging lub neej kev pab cuam thiab nce ROP (tus nqi nkag); Ua ke, cov yam ntxwv no muab lub zog ntau dua thiab ua rau muaj kev cuam tshuam thiab hnav, nrog rau kev txiav kom zoo dua thiab ua kom sov. Qhov no txhais rau hauv kev txhim kho durability thiab dull tej yam kev mob rau kev tswj siab tshaj plaws ROP thoob plaws hauv kev khiav.

Yog tias koj txaus siab rau PDC cutters thiab xav paub ntau ntxiv thiab cov ntsiab lus, koj tuaj yeem tiv tauj peb hauv xov tooj lossis xa ntawv ntawm sab laug, lossis xa US MAIL hauv qab ntawm nplooj ntawv.
