Vuggy porosity yog ib hom porosity hauv cov pob zeb carbonate. Zoo li no porosity Nws cuam tshuam rau permeability, siab poob thiab rov qab zoo nyob rau hauv lub reservoir. Yog li ntawd, lawv cov kev txheeb xyuas thiab kev ua qauv yog ib qho tseem ceeb rau lub reservoir characterization thiab keeb kwm txuam.
Hais txog qhov no, porosity txhais li cas?
Porosity yog qhov zoo ntawm kev ua ntxeem tau , lossis tag nrho ntawm qhov me me. Cov kua dej mus ncaj qha los ntawm cov khoom uas muaj porosity . Rov qab mus deb txaus thiab koj yuav pom qhov ntawd porosity stems los ntawm Greek lo lus poros rau "pore," uas txhais tau tias “kev.” Yog li qee yam nrog porosity cia tej yam dhau mus.
Ntxiv mus, dab tsi yog qhov feem pua porosity zoo? Nws yog txhais raws li qhov piv ntawm qhov ntim ntawm cov voids los yog pore qhov chaw faib los ntawm tag nrho cov ntim. Nws tau sau raws li ib feem ntawm zauv nruab nrab ntawm 0 thiab 1 lossis raws li a feem pua . Rau feem ntau pob zeb, porosity Nws txawv ntawm tsawg dua 1% mus rau 40%.
Raws li, cov piv txwv ntawm porosity yog dab tsi?
Porosity txhais tau tias yog tag nrho ntawm qhov me me uas dej lossis cua tuaj yeem hla tau. Ib qho piv txwv ntawm porosity yog qhov zoo ntawm daim txhuam cev.
Koj ntsuas qhov porosity li cas?
Ntsuas porosity Muaj ntau txoj hauv kev tuaj yeem ua haujlwm rau ntsuas porosity : imbibition txoj kev, piv txwv li, immersion ntawm tus qauv ntxeem tau, nyob rau hauv lub nqus tsev vacuum, nyob rau hauv ib tug dej uas preferentially ntub lub pores. Txoj kev ua kom dej txaus (ntim qhov pore = ntim tag nrho cov dej - ntim dej tawm tom qab soaking).

Dab tsi cuam tshuam rau porosity thiab permeability?
Cov yam ntxwv porosity thib ob, zoo li kev tawg, feem ntau muaj qhov cuam tshuam loj rau kev nkag mus ntawm cov khoom. Ntxiv nrog rau cov yam ntxwv ntawm cov khoom siv, lub viscosity thiab siab ntawm cov kua kuj cuam tshuam rau tus nqi uas cov kua yuav ntws
Dab tsi tswj cov khoom siv porosity?
Porosity ntawm pob zeb Porosity yog qhov piv ntawm qhov ntim pore rau nws cov ntim tag nrho. Kev porosity yog tswj los ntawm: hom pob zeb, kev faib pore, kev sib koom ua ke, kev txheeb xyuas keeb kwm yav dhau los thiab muaj pes tsawg leeg. Porosity tsis yog tswj los ntawm grain loj, raws li qhov ntim ntawm nruab nrab-grain qhov chaw tsuas yog cuam tshuam rau txoj kev ntim cov nplej
Cov mis rau porosity yog dab tsi?
Thawj qhov sib npaug siv tag nrho cov ntim thiab qhov ntim ntawm qhov khoob. Porosity = (Volume of Voids / Total Volume) x 100%. Qhov sib npaug thib ob siv tag nrho cov ntim thiab qhov ntim ntawm cov khoom. Porosity = ((tag nrho ntim - ntim ntawm cov khoom) / Total Volume) x 100%
Dab tsi yog qhov kev sib raug zoo ntawm kev ntxhib los mos thiab porosity?
Porosity nyob ntawm ob qho tib si av kev ntxhib los mos thiab qauv. Piv txwv li, cov av zoo muaj me me tab sis ntau qhov pores ntau dua li cov av ntxhib. Cov av ntxhib muaj qhov loj dua li cov av zoo, tab sis nws muaj qhov porosity tsawg, lossis qhov chaw pore tag nrho
Av porosity yog dab tsi?
'Soil porosity' hais txog qhov pores, lossis qhov chaw qhib, nruab nrab ntawm cov av. Qhov chaw pore tuaj yeem tsim los ntawm kev txav ntawm cov hauv paus hniav, worms, thiab kab; nthuav cov pa hauv cov chaw no los ntawm cov dej hauv av; thiab/los yog kev sib cais ntawm cov av niam txiv cov khoom. Av kev ntxhib los mos kuj tuaj yeem cuam tshuam cov av porosity
