Cov khoom xyaw tseem ceeb ntawm Roj Drilling Additives

 

Cov khoom xyaw tseem ceeb ntawm cov roj drilling additives muaj xws li cov hauv qab no:

Tus neeg saib xyuas qhov hnyav: feem ntau yog siv los ua kom lub ntiajteb txawj nqus ntawm cov dej drilling, sib npaug tsim siab lossis tiv thaiv kev sib tsoo. Cov khoom hnyav hnyav yog barite (BaSO4).
Fluid poob reducer: siv los txo qhov poob ntawm cov dej drilling rau hauv kev tsim thiab tiv thaiv kev ruaj ntseg ntawm phab ntsa zoo. Cov kua dej tsis tshua muaj xws li carboxymethyl cellulose, hydroxyethyl cellulose thiab hloov cov hmoov txhuv nplej siab.
Dispersant: thaum lub concentration ntawm av nplaum thiab laum cuttings nyob rau hauv lub drilling kua yog siab dhau heev lawm, cov dispersant yuav ua txhaum lub spatial network qauv thiab txo cov viscosity thiab shear quab yuam ntawm cov drilling kua. Feem ntau siv dispersants suav nrog lignin sulfonate thiab nws cov complex.
Viscosifier: xws li sodium carboxymethyl cellulose (CMC), siv los ua kom cov viscosity ntawm cov dej drilling, xyuas kom meej tias cov cuttings tuaj yeem nqa mus rau hauv av, thiab tiv thaiv kev sib tsoo hauv qab ntawm qhov dej.
Lub luag haujlwm thiab qhov tseem ceeb ntawm cov additives hauv cov roj drilling:

Viscosifying nyhuv: CMC tuaj yeem ua kom cov viscosity ntawm cov dej drilling, xyuas kom meej tias cov txiav tuaj yeem nqa mus rau qhov chaw zoo, tiv thaiv kev sib tsoo hauv qab ntawm qhov dej, thiab ua kom cov drilling mus zoo.
Luvite txo cov nyhuv: CMC tuaj yeem txo qhov pom qhov poob ntawm cov kua dej drilling, txo qhov nkag ntawm cov dej drilling rau hauv kev tsim, tswj kev ruaj ntseg ntawm cov dej drilling kev ua tau zoo, thiab tiv thaiv kom tsis txhob muaj kuab paug ntau dhau thiab kev puas tsuaj rau kev tsim.
Kev ncua thiab nqa lub peev xwm: CMC muaj peev xwm tshem tawm tau zoo, tuaj yeem nqa cov txiav, ntxuav kom huv, ruaj khov ntawm phab ntsa zoo, tiv thaiv cov av nkos, thiab tiv thaiv lub laum me ntsis.
Rheology tswj: CMC ua tau zoo hauv kev tswj rheology, haum rau cov av nkos ntawm qhov sib txawv, thiab tuaj yeem kho cov viscosity thiab rheology ntawm av nkos raws li cov xwm txheej tshwj xeeb.
