Formation of Hydrocarbon Deposits in the Riphean-Lower- Paleozoic Sedimentary Basin in the Southern Siberian Platform

In fluidodynamic theories activated deep faults with a key characteristic "activated" are an important and integral part of the oil and gas basins. The influence of fault tectonics on the processes of oil and gas formation is generally recognized and reflected in a variety of publications, but the mechanism of influence that is associated with the activation parameters: cyclicity of manifestation, generation redirection, time and the period of activation of fault systems, remains insufficiently studied [10, 11, 12, 13, 14]. Previously, in the marginal depressions of the east of the Siberian platform (Viluy Syneclise), carried out by several sedimentary basins (OPB), periodic processes of different ages activation of previously laid deep fault systems with various directions and generations were established. It’s argued that the formation of hydrocarbon deposits in the synchronous sediments of the same Riphean-lower Paleozoic OPB on-site of Nepa-Botuoba anteclise was due to subvertical fluid flows from underfoundation sources and processes of reformation of hydrocarbon deposits between productive layers under the influence of the periodic re-activation of fault systems with different spatial orientation. Deposits in productive formations of the terrigenous Vendian complex form under the influence of fault activation of early North-East, North of the North-East and submeridional generations. But in productive carbonate horizons of Wend-Cambrian and Lower Cambrian deposits form at the cost of reformation of deposits in the vendian deposits as affected by late north-west generation faults in the zones of overlaying on earlier generation. Oil exploration in the carbonates is recommended in the areas adjacent to the selected fault systems.
