Shale muaj cov qauv pob txha-pore tshwj xeeb, feem ntau ntawm lawv yog microcapillary pores nrog me pore caj pas thiab qis permeability. Nws yog qhov nyuaj rau daim ntawv ntim cov lim lim rau ntawm phab ntsa borehole, uas ua rau muaj kev lim hiam ntawm pob zeb, uas ua rau lub cev qhuav dej ntawm phab ntsa borehole.
Ntxiv nanomaterials rau drilling kua yuav ua tau zoo kaw nanoscale pore caj pas, thiaj li stabilize zoo phab ntsa thiab tiv thaiv reservoir.
Qhov loj thiab cov ntsiab lus ntawm cov khoom siv rau kev sib khi yog qhov tseem ceeb, uas yuav tsum xyuas kom tsis muaj kev nkag mus, thiab tseem tuaj yeem tsim cov ncuav qab zib nyias thiab tawv.
Cov pa ntsaws cov kab mob, xws li bentonite thiab barite, lawv qhov loj me me loj dua qhov nruab nrab qhov pore caj pas loj ntawm shale, uas tuaj yeem daws qhov teeb meem ntawm micron-scale pores. Lawv tsis yooj yim los tiv thaiv qhov tsis pom, thiab feem ntau sau rau ntawm qhov chaw yam tsis tau nkag mus tob rau hauv txheej txheej, lawv tsis tuaj yeem ua tiav cov nyhuv sealing los yog tsim lub ncuav mog qab zib compact lim kom txo qhov pom poob.
Nanomaterials muaj cov khoom tshwj xeeb ntawm cov nyhuv me me thiab cov nyhuv saum npoo, tsawg dua, nyob rau hauv txoj kab nrog txoj kev loj hlob ntawm cov dej drilling mus rau cov khoom qis lossis tsis muaj theem, kuj muaj cov cuab yeej lubricating zoo thiab cov yam ntxwv rheological, uas muaj txiaj ntsig zoo los txhim kho kev ua haujlwm tawg. thiab kev ua haujlwm ntub dej ntawm cov dej drilling, Cov nyhuv sealing zoo dua, tsim cov av nkos ncuav mog qab zib thickness tsawg dua 1 hli.
(Qhov txawv ntawm av nkos ncuav mog qab zib ua ntej thiab tom qab ntxiv rigid nanometer plugging tus neeg saib xyuas)
Nanomaterials muaj kev ua haujlwm siab heev, yooj yim los ua ke nrog lwm cov atoms, ruaj khov nrog cov tshuaj lom neeg ua haujlwm siab.
Tsis tas li ntawd, cov khoom ntawm nanomaterials feem ntau yog 1-100 nanometers nrog kev sib npaug sib npaug, uas yooj yim rau kev nkag mus rau micro-fractures ntawm shale, ua lub luag haujlwm ntawm kev txhaws thiab ruaj khov, tuaj yeem kaw cov pob txha zoo dua thiab tsim cov txheej txheem ntom ntom ntom ntom. kom tsis txhob pom kev poob.
Core ua ntej ntxiv tus neeg sawv cev ntsaws Core tom qab ntxiv 1 feem pua plug tus neeg sawv cev
Vim lawv lub cev thaiv cov nyhuv, nanomaterials tuaj yeem txhim kho rheological ntawm drilling kua, txhim kho lawv cov thermal stability, av nkos compactness, thiab lubrication.
Yog li ntawd, nanomaterials ua lub luag haujlwm tseem ceeb hauv cov kua dej drilling, uas tuaj yeem txo qis kev pom, txhim kho lubrication kev ua tau zoo, txhim kho kev tsim cov kabmob muaj peev xwm, stabilize qhov dej, tiv thaiv reservoir.
