Popis: | In order to study the influence of sedimentation conditions on filtering-capacity properties researches of relative gas saturation of Donbas sandstones of different lithogenetic types are conducted, they contain coals of grade composition from long-flame to the lean. River-bed sandstones (relative gas saturation 85–90%) are the most gas-saturated from a number of investigated materials, and consequently potentially gas-bearing containing coals of the metamorphism low stages (up to and including fat coal step). However, sandstones of the under water rivers carry-over (relative gas saturation 65–72%) are the most perspective for the search of methane accumulations, both from reservoir properties point of view as well as taking into account their volumes in the coal-bearing strata. |
