Cementation txo cov porosity thiab permeability ntawm cov xuab zeb. Qee qhov xwm txheej, txawm li cas los xij, kev daws cov cement lossis nplej tuaj yeem thim qhov qauv no.
Dab tsi cuam tshuam rau lub pob zeb porosity?
Ntau yam tuaj yeem cuam tshuam qhov porosity. Nyob rau hauv cov pob zeb sedimentary thiab sediments, tswj ntawm porosity muaj xws li sorting, cementation, overburden stress (txog rau faus qhov tob), thiab grain shape.
Puas sediment loj cuam tshuam qhov porosity?
Rau cov av tsis sib xyaw, qhov loj dua cov nplej loj, qhov porosity qis dua(Table 1). b. Rau consolidated shale thiab sandstone sediments, qhov loj ntawm cov nplej loj, qhov porosity siab dua.
Lub luag haujlwm ntawm cementation yog dab tsi?
Cementation, hauv geology, hardening thiab welding ntawm clastic sediments (cov tsim los ntawm cov pob zeb uas muaj nyob rau hauv cov pob zeb) los ntawm nag lossis daus ntawm cov ntxhia hauv qhov pore. … Cov cement tsim ib qho tseem ceeb thiab tseem ceeb ntawm pob zeb, thiab nws cov nag lossis daus cuam tshuam rau qhov porosity thiab permeability ntawm pob zeb.
Compaction thiab cementation cuam tshuam li cas rau qhov porosity ntawm pob zeb sedimentary?
Compaction yog txheej txheem kuaj mob uas pib ntawm kev faus neeg thiab tej zaum yuav txuas ntxiv thaum lub sij hawm faus rau qhov tob ntawm 9 km (30, 000 ft) lossis ntau dua. Kev ntsuas nce nce qhov ntom ntom ntawm pob zeb, nce nws txoj kev muaj peev xwm, thiabo-txo porosity.

Puas muaj kev cuam tshuam cuam tshuam qhov ua rau?
Thaum ua rau muaj kev cuam tshuam thiab kev sib raug zoo tuaj yeem tshwm sim nyob rau tib lub sijhawm, kev sib raug zoo tsis txhais hais tias ua rau. Kev ua txhaum yog siv rau cov xwm txheej uas qhov kev txiav txim A ua rau qhov tshwm sim B.
Puas txheeb xyuas zoo cuam tshuam qhov porosity?
Porosity yog hais txog lub peev xwm ntawm lub ntiaj teb cov ntaub ntawv los tuav cov dej hauv qhov chaw pom nyob rau hauv thiab nruab nrab ntawm sediments thiab pob zeb. … Yog li, zoo sorted sediments muaj porosity ntau duathaum tsis zoo sorted sediments muaj tsawg porosity.
Cementation puas cuam tshuam rau porosity?
Cementation txo cov porosity thiab permeability ntawm cov xuab zeb. Qee qhov xwm txheej, txawm li cas los xij, kev daws cov cement lossis nplej tuaj yeem thim qhov qauv no. Dab tsi cuam tshuam rau qhov porosity ntawm sediments lossis pob zeb?
Puas yog porosity thiab permeability cuam tshuam?
Qhov tshwj xeeb tshaj yog, qhov porosity ntawm pob zeb yog qhov ntsuas ntawm nws lub peev xwm tuav cov kua dej. … Permeability yog ib qho kev ntsuas ntawm qhov yooj yim ntawm cov kua ntws los ntawm cov khoom ntxeem tau. Lub pob zeb yuav ntxeem tau heev, tab sis yog tias cov pores tsis txuas nrog, nws yuav tsis muaj permeability.
Qhov twg yog tus cuam tshuam lossis cuam tshuam?
Txoj cai lij choj, kev cuam tshuam yog ib txoj hauv kev tso cai rau ib tus neeg tsis yog tog, hu ua intervenor (tseem sau tus neeg cuam tshuam) los koom nrog kev sib foob txuas mus ntxiv, txawm tias muaj cai lossis kev txiav txim siab ntawm lub tsev hais plaub, tsis tau tso cai los ntawm thawj tus neeg foob.
