Khoom taw qhia

Cov khoom muag yog xim av hmoov, soluble nyob rau hauv dej, dej tov yog qaug zog acid. Qhov hnyav molecular yog tsim nyog rau viscosity txo cov txheej txheem ntawm drilling av nkos tshaj li ntawm ferrochrome lignosulfonate.

Nyob rau tib lub sijhawm, cov ntsiab lus ntawm cov hlau hauv cov khoom yog tsawg dua 0.8%, kom tsis txhob muaj kuab paug ntawm cov hlau ions rau cov roj Wells, yog li chromium lignin yog ib hom av nkos viscosity reducer nrog kev ua haujlwm zoo sib xws lossis (zoo dua me ntsis) nrog ferrochrome ntsev. , thiab muaj kuab paug tsawg rau cov roj Wells.

Chrome lignosulfonate muaj nuj nqi ntawm kev txo cov dej poob thiab diluting, thiab kuj muaj cov yam ntxwv ntawm ntsev tsis kam, kub tsis kam thiab zoo compatibility. Nws yog diluent nrog muaj zog ntsev tsis kam, calcium tsis kam thiab kub tsis kam. Cov khoom siv dav siv hauv cov dej tshiab, dej hiav txwv, dej qab ntsev cov av nkos, txhua yam calcium kho av nkos thiab cov av nkos ultra-dub zoo, uas tuaj yeem txhim kho cov phab ntsa borehole thiab txo cov av nkos thiab txiav.

Kev ua haujlwm hauv av

(1) 150 ~ 160 ℃ rau 16 teev kev ua haujlwm tsis hloov;

(2) 2% brine slurry kev ua tau zoo dua li Ferrochrome Lignosulfonate;

(3) muaj zog electrolytic tsis kam, haum rau txhua yam av nkos.
