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?
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 Lithification nce porosity?
Piv txwv li, digenetic dolomitization yuav ua rau nce mus rau 13% porosity, uas tuaj yeem raug rhuav tshem tom qab los ntawm cementation lossis txhim kho los ntawm kev sib cais. Inasmuch raws li cov txheej txheem mechanical yog unidirectional thiab feem ntau irreversible, tejzaum lawv ua lub luag haujlwm tseem ceeb hauv kev hloov cov thawj (primary) porosity ntawm carbonate 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.
Yuav ua li cas thaum cementation?
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. Nws yog theem kawg ntawm kev tsim cov pob zeb sedimentary.

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.
Lub sijhawm cuam tshuam-driven io voj voog dab tsi ua rau muaj kev cuam tshuam?
CPU muaj cov kab thov cuam tshuam uas tau hnov tom qab txhua qhov kev qhia. Ib lub cuab yeej tswj hwm tsa qhov cuam tshuam los ntawm lees paub lub teeb liab ntawm kev cuam tshuam thov kab. CPU tom qab ntawd ua lub xeev txuag, thiab hloov kev tswj mus rau qhov cuam tshuam tus neeg ua haujlwm niaj hnub ntawm qhov chaw nyob ruaj khov hauv nco.
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.
Puas cementation cuam tshuam qhov 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 lub pob zeb porosity? Ntau yam tuaj yeem cuam tshuam qhov porosity.
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.
