Cov ntsiab lus
OBF-VIS yog tsim los ntawm ntau yam biopolymers thiab siv cov cuab yeej dispersion technology los txhim kho cov khoom tawg thiab tiv thaiv "ntses qhov muag".Cov khoom tsis yooj yim los ntawm cov ions yaj thiab tsim nyog rau cov dej qab zib, dej hiav txwv, thiab cov dej brine drilling, ua tiav cov txiaj ntsig siab "YP" thiab "LSRV".
Nta
All-biological khoom, uas yuav tsis ua mob rau tib neeg lub cev thiab ib puag ncig.
Zoo ntsev tsis kam, zoo heev viscosity nce thiab lifting txiav nyob rau hauv saturated brine.
High low shear rate viscosity, uas zoo tswj qhov tob tob ntawm drilling kua filtrate rau hauv kev tsim thiab tiv thaiv cov roj thiab roj reservoirs.
Kev tsim cov gel zoo li ze ze ntawm phab ntsa zoo tiv thaiv kev tsim ntawm "chip txaj", uas yog tshwj xeeb tshaj yog haum rau drilling cov kab rov tav qhov dej nrog txoj kab nqes loj thiab kev hloov pauv loj.
Cov nyhuv synergistic ntawm cov ntaub ntawv txhim kho qhov kub thiab txias ntawm cov ntaub ntawv lom neeg thiab tsim nyog rau drilling hauv formations nrog kub ntawm 120 ° C.
