Lithological and petrophysical studies of terrigenous rocks

The analysis of the results of lithological and petrographic studies of terrigenous rocks of Jurassic age of the Jelly deposit is given. Filtration-capacitance characteristics of rocks with establishment of boundary values of reservoirs are determined. By the example of the Jell-field it is shown that the petroelastic modeling helps to reconstruct the acoustic logging values in the areas of their partial or complete absence. Based on Rocks physics and analysis of petroelastic bonds terrigenous reservoirs in Jurassic sediments are detailed. Complexation of all data made it possible to identify and estimate the stress state of screen strata which are host rocks of productive sediments.
