| Secondary processes in the Achimov Formation sandstones on the example of the Ach 18-1 productive level of Yamburg area (Western Siberia) | |
| Analytical data interpretation of from studies of four wells Ach-18 productive level from Yamburg area made it possible to identify a sequence of staged secondary processes in clastic rocks and evaluate their role in the formation of reservoir properties. The processes of metasomatism and dissolution of feldspars and mafic micas (biotite, chlorite) have been traced, and their genetic substantiation has been given. Quantitative characteristics of secondary processes correlate well with porosity and permeability parameters. Keywords: Achimov Formation sandstones, secondary processes, metasomatism, dissolution, reservoir properties, Yamburg area, Western Siberia. |
