Xuab zeb nqa thickener rau roj drilling
vim li cas xaiv peb
vim li cas thiaj xaiv peb cov khoom
Tus neeg saib xyuas txheej yog cov khoom dawb los yog hmoov.Cov txheej txheem yog ib lub siab molecular polymer tsim los ntawm copolymerization ntawm derivatives ntawm ntau pab pawg, uas yog ib tug siab molecular dej-soluble polymer.
polymer muaj hydrophilic pawg xws li anions, uas ua rau nws resistant rau kub thiab ntsev thaum inhibiting lub hydration ntawm shale.Soluble nyob rau hauv dej.Nws yog ib tug zoo txheej tus neeg saib xyuas rau drilling kua.Nws muaj peev xwm hloov lub rheological
Tsis siv neeg drilling kua, nce lub peev xwm shear dilution, txo qhov pom, thiab lub tsho loj dilling cuttings.Nws yog tsuas yog siv rau dispersing polymer dej-raws li drlling kua nyob rau hauv uas tsis muaj cov khoom.

cov khoom piav qhia
Sand carrier concentrates rau roj drilling yog tshwj xeeb sib xyaw ntawm polymers thiab lwm yam additives tshwj xeeb tsim los thauj cov xuab zeb, minerals, thiab lwm yam drilling khib nyiab thaum txo cov dej poob.
01
Cov khoom no yog tsim los txhim kho cov txheej txheem drilling, tshwj xeeb tshaj yog nyob rau hauv ib puag ncig nyuaj uas muaj kev pheej hmoo siab ntawm cov laum me ntsis tau daig vim muaj cov av khib nyiab. Los ntawm kev khaws cov khib nyiab hauv kev ncua, cov khoom tso cai rau cov av nkos kom ntws sai thiab ua tau zoo, txo qhov kev pheej hmoo ntawm cov khoom puas tsuaj thiab tsis tau npaj tseg.
02
Ib qho ntawm cov txiaj ntsig tseem ceeb ntawm cov xuab zeb uas muaj cov thickeners siv hauv cov roj drilling yog lawv cov viscosity siab. Cov khoom muaj ib tug tuab, viscous sib xws uas pab tshem tawm deposits thiab lwm yam khib nyiab uas yuav clog drilling kua. Cov khoom lag luam siab viscosity kuj txhais tau hais tias nws tuaj yeem nyob hauv ncua sij hawm ntev, txo qhov xav tau kom nquag ntxiv cov dej drilling.
03
Lwm qhov tseem ceeb ntawm cov xuab zeb-cov kabmob thickeners rau cov roj drilling yog lawv qhov kev cuam tshuam ib puag ncig qis. Nws yog non-toxic thiab muaj kev nyab xeeb rau siv nyob rau hauv cov cheeb tsam uas tsis muaj zog ecosystems. Cov khoom no tsis muaj cov tshuaj phem uas yuav ua rau muaj kev kis kab mob lossis kev puas tsuaj rau cov dej hauv dej. Tsis tas li ntawd, nws yog biodegradable heev thiab yooj yim rau pov tseg tom qab siv.
04
Xuab zeb mloog zoo rau cov roj drilling yog cov khoom siv tau zoo uas tuaj yeem txhim kho kev ua haujlwm thiab kev ua tau zoo ntawm cov txheej txheem drilling.
