Hauv roj av geology , qhov chaw pob zeb hais txog pob zeb los ntawm cov hydrocarbons tau tsim los yog muaj peev xwm tsim tau. Roj shale tuaj yeem suav tias yog cov organic nplua nuj tab sis tsis paub qab hau qhov chaw pob zeb los ntawm cov roj me me lossis tsis muaj roj tau raug tsim tawm thiab raug tshem tawm.
Ib yam li ntawd, nws raug nug, dab tsi yog pob zeb thiab pob zeb reservoir?
Cov qhov chaw pob zeb yog qhov chaw tsim cov roj. Nws muaj cov organic teeb meem uas tau them sai sai los ntawm cov av nplaum me me hu ua shale. Thaum cov roj yog "tsim" nyob rau hauv lub qhov chaw pob zeb nws txav mus rau qhov pob zeb reservoir (Sandstone) qhov twg nws khaws cia kom loj hlob.
Qhov thib ob, dab tsi yog pob zeb hauv cov roj thiab roj? Source pob zeb . Daim duab 1. Ib qho tshuaj tiv thaiv kab mob roj thiab roj reservoir . Qhov chaw pob zeb yog pob zeb uas muaj cov khoom siv organic txaus los tsim cov hydrocarbons thaum raug tshav kub thiab siab dhau sijhawm. Qhov chaw pob zeb feem ntau yog shales los yog limestones (sedimentary pob zeb ).
Ntawm no, qhov chaw pob zeb tsim li cas?
Cov zaub mov ntxiv, hnub ci, qhov kub thiab txias, pH thiab Eh ntawm dej, sediments, thiab cov av cuam tshuam rau kev tsim khoom lom neeg. Source pob zeb daim ntawv qhov twg depositional tej yam kev mob vaj tse organic teeb meem los ntawm kev puas tsuaj los ntawm oxidation thiab los ntawm huab dilution los ntawm cov ntxhia input.
Dab tsi yog Seal Rock hauv geology?
1.n ib. [ Geology ] Ib tug kuj impermeable pob zeb , feem ntau shale, anhydrite los yog ntsev, uas tsim ib qho kev thaiv los yog hau saum toj thiab ib ncig ntawm lub reservoir pob zeb xws li cov kua dej tsis tuaj yeem hla dhau lub reservoir. A foob yog ib qho tseem ceeb ntawm cov roj av ua tiav.

Dab tsi yog qhov txawv ntawm cov pob zeb tsis foliated thiab foliated metamorphic pob zeb?
Foliated metamorphic pob zeb xws li gneiss, phyllite, schist, thiab slate muaj ib txheej txheej los yog banded zoo li uas yog tsim los ntawm raug tshav kub thiab qhia siab. Non-foliated metamorphic pob zeb xws li hornfels, marble, quartzite, thiab novaculite tsis muaj txheej txheej lossis banded zoo li
Dab tsi yog pob zeb tsim cov ntxhia pob zeb?
Cov pob zeb tsim cov zaub mov yog: feldspars, quartz, amphiboles, micas, olivine, garnet, calcite, pyroxenes. Minerals tshwm sim nyob rau hauv ib lub pob zeb nyob rau hauv me me yog hu ua "accessory minerals"
Lub npe rau lub pob zeb nruab nrab ntawm cov pob zeb uas txias heev yog dab tsi?
Extrusive igneous pob zeb
Dab tsi yog cov pob zeb niam txiv ntawm cov pob zeb metamorphic?
Metamorphic pob zeb Metamorphic pob zeb Texture Niam txiv pob zeb Phyllite Foliated Shale Schist Foliated Shale, granite thiab volcanic pob zeb Gneiss Foliated Shale, granite thiab volcanic pob zeb Marble Nonfoliated Limestone, dolostone
Lub pob zeb foliated twg yog qhov qis tshaj plaws metamorphic pob zeb?
slate Ua li no, marble puas yog qib qis metamorphic pob zeb? Qee qhov piv txwv ntawm non-foliated Cov pob zeb metamorphic yog marble , quartzite, thiab hornfels. Marble yog metamorphosed limestone. Thaum nws tsim, cov calcite crystals yuav loj hlob tuaj, thiab tej yam sedimentary textures thiab fossils uas muaj tam sim no raug puas tsuaj.
