Assessment of the relationship of reservoir properties of hydrocarbon fields in the Lower Kura depression (Kursengi and Southern Kursengi areas)


 The article is devoted to the analysis of geological-petrophysical properties Kursengi and Southern fields Lower Kura depression with a view clarify changes in physical (carbonate content, permeability, porosity) rocks depth. Promising sediments horizons deposits are also considered based on detailed numerous rock samples. Oil gas bearing objects especially distinguished by area, as well possible oil blocks. main purpose these studies unravel carbonate, porosity permeability depth core samples taken from drilled wells study area identify factors causing changes. To do this, using obtained data, dependences porosity, carbonate were compiled. As known, increasing depth, experience compaction. With not show any regularity, i. e. at some depths, an increase observed, decrease, this occurs abrupt manner. In our sections, critical depths decrease observed 500 m 1600 m, 2950 m. other words, reservoirs, general gradual begins sharply 3200 materials, it was found that characterized good reservoir properties. However, many studied samples, varies within wide range 12.8–27.8 %, ranges 0.001x10–15m2 120x10–15m2.
