Litho-petrophisical heterogeneity of the reservoir rocks
Based on the results of our studies, three litho-types of rocks have been identified, their structure characterized, influence of post-sedimentary transformations revealed, etc. Leaching, sulphatization and deposition of ore minerals are considered as the changes superimposed upon the background lithogenesis. The diversity of the processes has resulted in significant petrophysical heterogeheity of geological cross-section, which has to be taken into account during idevelopment of the layers, introduction of the intensive methods, etc.
