|The forecast of Achimov sandstone reservoirs (Hauterivian) on the western part of Surgut arch (Western Siberia)|
|Several groups of sandy-silty bodies, characterized by certain reservoir properties, were distinguished on the basis of relative amplitude of spontaneous polarization. Curves of spontaneous polarization are used for local forecast of sandy body-reservoir, zones of their pinching-out and associated lithological traps. The investigation of correlation between reservoir properties of sandstones and dynamic parameters of wave field was conducted. Inverse relationships between high correlation coefficients of net thickness of sand layer and net sand. coefficient and signal form and reflection coherence were analyzed. The north-east elongated narrow zones are traced from dynamic parameters of reflecting horizons that suggest discrete reservoir distribution in the Achimov strata. Such structure is confirmed by seismic time sections reprocessed using REAPAK.
Key words: sandstone-siltstone reservoirs, Achimov strata, relative amplitude of spontaneous polarization, local forecast.
