Abstract

Abstract:

Sandbodies in the Carboniferous Kalashayi Formation in the Tahe oilfield are characterized by deep burial depth,small thickness and great lateral viariation,which makes it hard to predict them.In this paper,the frequency division interpretation tecnique is used to identify and characterize thin sandstones in the Kalashayi Formation.Boundaries of multi-stage deposits in the sandsonte unit are identified by using the phase of certain frequency.The distribution of sandstone is traced according to tuning "bright spot" and the thickness of sandstone is calculated according to the frequency of first peak.The frequency division interpretation tecnique can successfully identify thin-sandstone reservoirs and improves the accuracy of reservoir prediction.

Key words: frequency division interpretation, thin sandstone, sandbody characterization, reservoir prediction
