1. Cov ntsiab cai yooj yim rau kev xaiv hardfacing
l Txhawm rau kom muaj kev tiv thaiv zoo thiab tiv thaiv cov cuab yeej downhole zoo dua xws li laum cov yeeb nkab sib txuas, cov kav dej tho qhov hnyav, thiab cov dab laum. Qhov tawv tawv ntawm txoj siv tawv hnav yuav tsum tsis txhob qis dua HRC55.
l Thaum drilling nyob rau hauv lub casing, thiaj li yuav tiv thaiv lub casing thiab txo nws cov hnav, xaiv hnav-resistant siv yuav tsum muaj zoo tiv thaiv kev sib txhuam.
l Qhov sib npaug ntawm kev tshawb fawb ntawm kev hnav tsis kam thiab kev sib txhuam txo.
l Feem ntau, nws raug nquahu kom siv hardfacing nrog "nce" zoo, thiab tsis pom zoo kom siv hardfacing nrog "paj" zoo. Tsuas yog thaum lub siab tshaj plaws sab nraud ntawm lub laum yeeb nkab sib koom ua ke tsuas yog txwv kom tsis txhob cuam tshuam nrog txoj kab nruab nrab ntawm lub casing, nws pom zoo kom siv lub "paj" zoo li tus hnav-resistant strip. Txhua hom hnav-tiv taus sawb welded nyob rau hauv txoj kev no tsis tuaj yeem tsim qhov siab tshaj plaws hnav-tiv taus vim tias ob qho tib si sab nraud ntawm lub laum yeeb nkab sib koom ua ke thiab cov sawb hnav-tiv taus tau hnav tib lub sijhawm.
2. Cov kev xav tsis zoo hauv kev xaiv hardfacing
Kev ntseeg yuam kev 1:Tungsten carbide hnav-tiv taus txoj siv yog qhov zoo tshaj plaws hnav-tiv taus siv los tiv thaiv laum rods
Tom qab cov tungsten carbide hnav-resistant sawb yog welded mus rau lub laum yeeb nkab sib koom, cov ntse tungsten carbide hais ua rau micro txiav ntawm lub casing, ua rau hnyav casing hnav.
Ntau lub tuam txhab roj txawv teb chaws muaj cov qauv sab hauv uas txwv tsis pub siv tungsten carbide hardfacing. Qee qhov chaw roj hauv tsev kuj txwv tsis pub siv.

Kev ntseeg yuam kev 2: Xaiv hardfacing uas dhau mus ua kom txo qis kev sib txhuam thiab kev txi hnav tsis kam
l Txhawm rau tiv thaiv lub casing thiab txo nws txoj kev hnav, kev ua haujlwm ntau dhau ntawm kev sib txhuam kev ua haujlwm ntawm txoj siv tawv-tiv taus kev txi nws hnav tsis kam.
ü Txoj siv tawv-tiv taus yog yooj yim hnav tawm, ua rau muaj kev sib cuag ncaj qha ntawm lub laum yeeb nkab sib txuas thiab cov casing lossis tsim qhov zoo. Raws li paub zoo, qhov hnav ntawm cov yeeb nkab tho yeeb nkab sib koom ua ke thiab cov casing los yog tsim lub qhov dej zoo ntau dua li ntawm cov yeeb nkab laum sib koom ua ke nrog txoj siv tawv-tiv taus, ua rau hnyav hnyav ntawm lub casing thiab thaum ntxov tsis ua hauj lwm ntawm cov yeeb nkab laum. vim hnav ntau dhau.
ü Lub neej luv luv ntawm hardfacing nce lawv cov nqi siv.
