English term

porosity

GBK English to Serbian Science Petroleum Eng/Sci
The volume of spaces within rock that might contain oil and gas (like the amount of water a sponge can hold); the open or void space within rock – usually expressed as a percentage of the total rock volume. Thus porosity measures the capacity of the rock to hold natural gas, crude oil or water.
Example sentences:
The porosity profile in any individual well depends on the maximum effective stress, which is generally determined by the maximum burial depth. (U.S. Geological Survey)
Carbonate reservoirs have lower values of median and maximum porosity for a given burial depth, probably because of greater chemical reactivity of carbonate minerals relative to quartz and the resulting lower resistance to chemical compaction and associated cementation. (GeoScienceWorld)
Porosity and permeability reduction due to burial and compaction acts differently on different sediment types. Sandstone is more resistant to porosity and perm reduction due to compaction, whereas shales and siltstone are generally more prone to perm reduction. (All Experts)

poroznost

Dijatomiti su meke, lake i porozne stene izgrađene od ostataka ljušturica dijatomeja. Zapreminska masa im je manja od jedinice, a kod kvalitetnih varijeteta iznosi 0,5-0,7 pa čak i 0,25-0,30 g/cm2. Poroznost dostiže i do 75 %, a sadržaj celih ljuštura do 30 miliona u 1 cm3. Boje su bele, sive, žućkaste, smeđe.

Ova osobina predstavlja odnos između zapremine šupljina u stenskoj masi i njene ukupne zapremine. <br />Budući da neispunjeni prostor u stenskim masama može biti različitog porekla, imamo singenetsku ili primarnu i epigenetsku ili sekundarnu poroznost. Primarne šupljine u stenama su pukotine lučenja, ovalni mehurići u vulkanitima nastali usled zaostalih gasova (mehuraste teksture), dok sekundarne šupljine predstavljaju tektonske pukotine, kavernoznost karbonatskih i drugih sedimentnih stena nastala erozijom ili rastvaranjem pojedinih komponenata itd.<br />Poroznost stena je značajna osobina jer od nje zavisi upijanje, zadržavanje i kretanje vode kroz stene, strujanje vazduha i gasova, postojanost stena na mrazu i provodljivost toplote i zvuka.

Prema poreklu pora, poroznost može biti: primarna (nastala za vreme nastanka same stene) i sekundarna (nastale nakon litifikacije stenskih masa pod dejstvom novih faktora na stenu). (Natural Mineral Waters)
- POROZNOST (eng: Porosity; rus: Пористость) Svojstvo stene da sadrži pore i šupljine bez obzira na njihovu veličinu, raspored i povezanost. Izražava se procentom pora u odnosu na ukupnu zapreminu. Poroznost može biti: ukupna i aktivna poroznost, zatim primarna i sekundarna, intergranularna ili međuzrnska, sunđerasta ili šupljikava, pukotinska, kavernozna i sl. (Wikipedia)
