Stages and tendency of secondary transformations of reservoir rocks of Lower Tutleim subsuite on the west of Latitudinal Priobie
Based on results of detailed lithological studies of rocks in transparent sections and data of isotope analysis of carbonate minerals of rocks comprising deposits of Lower Tutleim subsuite (analog of Bazhenov suite on the west of Latitudinal Priobie) the stage analysis of rock transformation - potential reservoirs was carried out, there were revealed two main branches of lithogenesis. It was established an association between mineral composition of reservoir rocks and quality of rock-and-fluid properties of reservoirs. The best reservoir type of Lower Tutleim subsuite was identified; it was established a distinct stratigraphic confinement to the particular part of the section for simplicity of its searching.
