Establishment and Significance of Reservoir Thickness Spectrum

Abstract

Abstract: The study of reservoir thickness has direct and close relations with gas-oil prospecting and exploitation.The analysis of vertical and horizontal changes of reservoir thickness is of great significance for finding out lithologic oil-gas pools.This article puts forward a time domain-thickness spectrum method for reservoir imaging based on improved wavelet.The single-trace analysis method can be used to produce a seismic trace spectrum for analyzing vertical changes of reservoir thickness.When we analyze other seismic traces along seismic profiles, the horizontal changes of reservoir thickness can also be studied.Testing results show that this is a visual and high resolution method and has a value for application.

Key words: time, reservoir rock, frequency, thickness, resolution
