ROCK MECHANICS TEST AND ANALYSIS OF POROSITY PRESERVATION IN DEEP RESERVOIR

Abstract

Abstract: Resultsfrom rock mechanics tests and deep well drilling revealed that after sediments solidified into sedimentary rocks or magma condensed to igneous rocks, if the strata developed with higher porosity by dissolution, then such reservoir rocks can not lose their porosity due to overlaping formation pressure.If there is not large scale of cementation, the higher porosity of the rock can be preserved in the place over 7 000 ~ 8 000m in depth. Therefore, deep and super deep strata can also develop with high-quality oil and gas reservoir spaces.

Key words: Deep zone, Reservoir rock, Porosity, Perservation, Rock mechanics, Test, Analysis
