Porosity ntawm pob zeb
Porosity yog qhov sib piv ntawm qhov pore ntim rau nws qhov ntim tag nrho. Porosity yog tswj los ntawm: pob zeb hom, pore tis, cementation, digenetic keeb kwm thiab muaj pes tsawg leeg. Porosity tsis tau tswj hwm los ntawm qhov loj me, vim tias qhov ntim nruab nrab ntawm qhov chaw cog qoob loo tsuas yog cuam tshuam nrog txoj hauv kev ntim cov noob
Hauv qhov no, yam dab tsi cuam tshuam rau porosity?
Qhov degree ntawm porosity nyob ntawm cov khoom ntawm cov khoom noj thiab cov txheej txheem kom qhuav. Cov khoom muaj pes tsawg leeg, cov qauv tshiab, noo noo qhov loj, thiab cov qauv ntawm cov qauv yog cov yam ntxwv tseem ceeb ntawm cov khoom tseem ceeb cuam tshuam pore tsim thaum ziab.
kev sib txheeb ntawm porosity thiab permeability yog dab tsi? Porosity yog ntsuas seb ntau npaum li cas pob zeb qhib qhov chaw. Qhov chaw no tuaj yeem yog nruab nrab nplej los yog nyob rau hauv tawg los yog kab noj hniav ntawm lub pob zeb. Permeability yog ntsuas ntawm qhov yooj yim uas cov kua (dej hauv qhov no) tuaj yeem txav mus los ntawm ntxeem tau pob zeb.
Qhov zoo li cas cuam tshuam porosity?
Cov duab thiab qhov loj ntawm cov khoom cuam tshuam txoj kev uas lawv ntim ua ke nyob rau hauv ib tug tej yam npaum li cas ntawm qhov chaw, uas cuam tshuam ib rock porosity . Porosity hais txog qhov sib piv ntawm qhov ntim huab cua nyob hauv pob zeb mus rau qhov ntim tag nrho ntawm pob zeb.
Yam dab tsi ua rau muaj qhov porosity ntawm cov khoom?
Cov porosity ntawm ib cov av nyob ntawm ob peb yam , suav nrog (1) ntim khoom ceev , (2) qhov dav ntawm particle loj tis (polydisperse vs. monodisperse), (3) zoo li hais, thiab (4) cementing.

Cov cuab yeej lossis cov txheej txheem dab tsi yuav tus thawj tswj hwm qhov project yuav siv los tswj cov peev txheej?
Cov cuab yeej thiab cov txheej txheem ntawm Kev Tswj Scope. Variance Analysis yog ib txoj hauv kev uas siv los txiav txim siab txog qib thiab ua rau muaj qhov sib txawv uas tshwm sim ntawm qhov project hauv paus thiab qhov kev ua tau zoo tshwm sim thaum lub sijhawm ua tiav
Dab tsi yog qhov txawv ntawm cov neeg siv khoom thiab cov khoom tsim khoom?
Teb: Cov khoom siv yog cov khoom kawg rau kev noj cov neeg siv khoom kawg thaum cov khoom tsim khoom yog cov khoom siv raw rau lwm cov khoom lag luam. Teb: Cov neeg tsim khoom zoo yog ib qho siv los ntawm cov neeg tsim khoom: lub Hoobkas machinery, lub rooj ua haujlwm, cov ntaub ntawv raw thiab lwm yam
Dab tsi yog cov cuab yeej lossis cov txheej txheem siv los hloov cov ntaub ntawv kev ua haujlwm rau hauv cov ntaub ntawv kev ua haujlwm hauv cov txheej txheem tswj Scope?
Variance Analysis yog ib qho cuab yeej & Cov txheej txheem ntawm Kev Tswj Scope Txheej Txheem thiab Kev Ntsuas Kev Ua Haujlwm Ua Haujlwm (WPM) yog qhov tso tawm ntawm cov txheej txheem no
Tshooj 404 xav tau dab tsi ntawm kev tswj hwm cov ntaub ntawv tswj xyuas sab hauv tshawb fawb lub tuam txhab pej xeem thiab piav qhia txog kev tswj hwm cov ntaub ntawv ntawm kev tswj hwm sab hauv kom ua tau raws li cov cai ntawm ntu 40

Tshooj 404(b) xav kom ib lub tuam txhab tuav pov hwm tus neeg soj ntsuam los ua pov thawj rau, thiab tshaj tawm txog, kev tswj xyuas kev ntsuam xyuas ntawm nws cov kev tswj hwm sab hauv
Dab tsi yog cov khoom siv ncaj qha kev ua haujlwm thiab kev tsim khoom siv nyiaj siv ua haujlwm?
Hauv cov tuam txhab tsim khoom, cov khoom siv nyiaj siv ua haujlwm suav nrog tag nrho cov nqi tsim khoom tshwj tsis yog cov suav nrog cov khoom siv ncaj qha thiab kev ua haujlwm ncaj qha. Cov nqi tsim khoom siv nyiaj siv ua haujlwm yog cov nqi tsim khoom uas yuav tsum tau tshwm sim tab sis tsis tuaj yeem lossis tsis tuaj yeem taug qab ncaj qha rau cov khoom tshwj xeeb tsim
