Cov yam ntxwv ua haujlwm ntawm kev kub ceev shear twj tso kua mis
Sep 07, 2022
High shear homogenizing twj tso kua mis yog ib yam ntawm cov tshuab tshwj xeeb uas siv los shear polymer thiab av nplaum, uas tau siv nyob rau hauv lub teb thiab ua pov thawj zoo theoretically. Nyob rau hauv lub drilling kua system, lub polymer (los yog av nplaum) yuav tsum tau sheared tag nrho ua ntej nkag mus rau hauv lub drilling kua system muab tag nrho cov kev ua si rau nws cov nqi hluav taws xob thiab txhim kho cov kev ua tau zoo ntawm cov dej drilling. Yog hais tias nws tsis yog tag nrho sheared, lub polymer yuav thaiv lub vibrating npo nyob rau hauv * cycles, poob ib tug loj npaum li cas ntawm polymer, nce tus nqi drilling, thiab ua rau cov khoom loj loj nyob rau hauv cov dej drilling nyuaj kom tshem tawm; Nyob rau hauv cov kua tiav, cov polymer yuav tsim ntau "ntses ob lub qhov muag" vim tsis txaus shear. Cov "ntses ob lub qhov muag" no yuav ua rau kev tsim, txo qhov tsim permeability thiab txo cov roj thiab roj reservoirs.
Lub siab shear homogenization twj tso kua mis muaj peev xwm muab siab shear rau ceev ceev hydration ntawm polymer (los yog av nplaum), thiab daws cov teeb meem tseem ceeb ntawm tsis zoo hydration ntawm polymer (los yog av nplaum) nyob rau hauv drilling kua los yog ua tiav kua. Nyob rau tib lub sijhawm, kev siv lub twj tso kua mis shear tuaj yeem txo tus nqi ntawm cov polymer ntau dua 15 feem pua thiab cov nyiaj bentonite ntau dua 30 feem pua, txhim kho qhov poob ntawm cov av nkos thiab cov kua dej ntws tawm, txo qhov sib piv ntawm qhov drilling. kua, thiab txhim kho lub zog gel, mus txog qib siab ntawm cov khoom zoo sib xws txawv teb chaws. Nws cov qauv foob pob yog txhim khu kev qha, muaj kev ua tau zoo, thiab yooj yim dua rau kev siv thiab tu.
