pdf	Structure and formation conditions of the Lower Cretaceous reservoir BV-8 - Povkhovskoe oil field (Western Siberia)
	Structural and genetic analysis of cores and log data (SP curves) has shown that strata BV-8 of the Povkhovskoe oil field consists of 10 transgressive-regressive systems of layers, which were formed as a result of migration landscapes (deep muds, “rag sands” and sand dikes) during the rise and fall of the sea level. It has been found that sand strata are represented by lenses that consist of two layers: the lower (accumulated in the final phase of regression), and the upper (accumulated at the beginning of transgression of the next sedimentation cycle). The obtained results do not confirm the clinoform model of strata BV-8 due to low resolution of seismic profiling, which only allows to reveal some general boundaries of a number of diachronic sands lenses, that are located en echelon and overlap each other. Key words: sedimentary environments, transgressive-regressive cycles, structural and genetic analysis, clinoform, productive strata BV-8, Povkhovskoe oil field, Lower Cretaceous.
