Thermal Stability ntawm PDC Cutter

Thoob plaws hauv keeb kwm ntawm oilfield drilling, cov neeg ua haujlwm tau sim txhim kho kev xyaum ua kom zoo dua qub. Ntau qhov kev txiav txim siab, tsim, thiab cov khoom siv tau raug coj los ua kom nce tus nqi nkag (ROP), hnav tsis kam, thiab tag nrho lub neej me ntsis. Qhov tshwm sim ntawm PDC cutter (Polycrystalline Pob Zeb Diamond Compact Cutter) nyob rau hauv nruab nrab-1970s pib maj mam txav deb ntawm cov menyuam lub khob me ntsis mus rau lub shear cutter me ntsis.

Cov yam ntxwv ntawm PDC cutter zoo li kev cuam tshuam thiab kev puas tsuaj yog qhov tseem ceeb. Cov kev txwv kub thiab qhov cuam tshuam tsis zoo ntawm PDC cutter tau hais txog qhov chaw rau kev txhim kho.

Thermal stability yog qhov ruaj khov ntawm cov molecule ntawm qhov kub thiab txias. Ntawm chav kuaj, peb muab PDC cutters nyob rau hauv 700-750 ℃ ​​rau 10-15 feeb thiab tshuaj xyuas cov txheej txheem pob zeb diamond tom qab cua txias hauv huab cua kom pom tias PDC Cutters muaj thermal ruaj khov txaus nyob rau hauv qhov kub thiab txias ua haujlwm. Feem ntau, cov txheej txheem no yuav muab piv rau PDC cutter qhov zoo ua ntej qhov kev xeem thiab tom qab qhov kev xeem, xws li hnav-tiv taus thiab cuam tshuam tsis kam; Txias lub PDC cutter thaum kuaj VTL tso cai rau lub cutter kom dissipate tshav kub kom deb ntawm qhov chaw txiav mus rau cov kua. Qhuav los yog kub kuaj yuav tsum tau lub cutter kom dissipate lub tshav kub los ntawm conduction los ntawm nws tus kheej mus rau lub WC substrate thiab feem ntau ua sai sai rau mechanical puas, oxidation, thiab graphitization ntawm lub pob zeb diamond. Lub chaw kuaj qhuav lossis kub ntsuas zoo dua simulates cov xwm txheej ntawm qhov sib sib zog nqus, kub, thiab abrasive drilling xws li yuav ntsib nyob rau hauv ntau daim ntawv thov geothermal.

Ntau tus neeg pib paub tias qhov ntsuas kub tsis tau tswj tau thaum lub sij hawm brazing tsis zoo cuam tshuam rau cov kev ntxhov siab sab hauv ntawm PDC cutters. Qhov no ua rau kev ua tsis tiav thaum ntxov hauv kev pabcuam. Ntau tus neeg yuav cem PDC cutter rau qhov no vim lawv tsis paub txog cov teeb meem brazing kub tuaj yeem ua rau. Lawv liam tias PDC cutter chaw tsim khoom, thaum qhov tseeb nws yog lawv cov txheej txheem brazing uas ua rau muaj teeb meem. PDC cutter uas muaj qhov zoo thermal stability thaum lub sij hawm brazing txheej txheem yuav zoo heev los khaws cov khoom, tshwj xeeb tshaj yog rau kev kho kev lag luam.
