Muaj ntau ntau hom viscosity reducers rau dej-raws li drilling kua, uas tuaj yeem muab faib ua ob hom raws li lawv cov kev sib txawv ntawm kev ua, uas yog dispersive viscosity reducers thiab inhibitory viscosity reducers. Cov viscometers dispersive feem ntau suav nrog cov ntsev inorganic, tannins, lignosulfonates thiab lignite, thiab cov viscometers viscometers feem ntau suav nrog cov tsis tshua muaj molecular polymer viscometers thiab organosilicon viscometers. Lub ntsiab dispersive viscosity txo cov neeg ua haujlwm feem ntau siv rau ntawm qhov chaw yog sulfonated tannin extract (SMK), sulfonated tannin (SMT), sulfonated lignite (SMC), hlau chromium lignosulfonate (FCLS, feem ntau hu ua hlau chromium ntsev) thiab lwm yam. Txhawm rau txhim kho qhov ruaj khov ntawm qhov kub thiab txias tsis kam, lub dispersive viscosifier feem ntau muaj qee yam ntawm chromium ions.
Cov khoom tshiab: Ferrochrome lignosulfonate (FCL) yog cov khoom txuas ntawm lignosulfonate hauv sulfite-cellulose cawv nrog hlau sulfate (FeSO4) thiab sodium bichromate. FCL yog siv los txo cov viscosity thiab zoo li qub shear quab yuam ntawm drilling kua hauv paus ntawm cov dej tshiab thiab ntxhia, thiab tuaj yeem cuam tshuam me ntsis ntawm cov av nplaum decomposition.Siv lignosulfonate zoo thaum pH nyob nruab nrab ntawm 8.5 thiab 9.5.
Benchmarking khoom: Hloov kho fcl-Me Polythin.
Polythin yog acrylic raws li qhov hnyav molecular. Nws yog qhov ua tau zoo thinner / deflocculant nrog kev zam rau qhov kub thiab txias, sib txawv ceev faj, pH hloov pauv thiab salinity. Nws yuav hloov cov tsoos thinners nyob rau hauv feem ntau daim ntaub ntawv, tshaj cov khoom nyob rau hauv kev ua tau zoo thiab tus nqi zoo. Polythin yog siv los tswj rheological stability nyob rau hauv lub xub ntiag ntawm electrolyte paug los ntawm ntsev, gypsum thiab cement. Nws tseem yuav pab tiv thaiv cov av nkos gelation siab.
Txuag cov nqi drilling, xyuas kom zoo, xyuas kom lub sijhawm xa khoom.
