The physical properties of the Сambrian rocks of the Bug structure of the Podlassko-Brest depression
Abstract
The generalized results of studies of the physical properties of rocks along the section of Cambrian deposits (Rytskaya, Stradechskaya, Spanovskaya, Bugskaya and Orlinskaya formations) of the Pribug structure within the same-name underground gas storage (UGS) are presented. More than 120 rock samples evenly distributed throughout the thickness of the Cambrian deposits from the depth range of 889–1240 m were studied. The reservoir rocks are mainly quartz fine-and medium-grained sandstone with varying degrees of grading and grain rounding, type of cementation, clay content. The cap rocks are represented by clayey siltstone with the presence of small fine-grained sandstone and siltstone bands and by silty mudstone-like clays.
Laboratory research data include the results of the study of chemical, granulometric compositions of the rocks, determination of carbonate and clay minerals in the rocks, determination of density, open and closed porosity, gas and reservoir water permeability on the specially prepared samples, study of the pore space of the rocks using digital photographs. The established features of filtration-capacitance properties of the rocks can be used for carrying out activities and developing recommendations to improve the efficiency of using the pore space of the deposits of the structure aimed at upgrading operation of the Pribug gas storage.
