Abstract

Abstract:

Shoal reservoirs were encountered by Well Yuanba-7 and yielded high industrial gas flow from the Maokou Formation at the platform margins of Yuanba area in Sichuan Basin, marking a major breakthrough in oil and gas exploration frontiers.In order to confirm the seismic response characteristics and identification methods of the reservoirs, the study constructed a three-dimensional physical model of platform-margin shoal reservoirs consistent with the actual formation parameters of the studied area based on the comprehensive geological and seismic interpretations.The model were then modified according to acquired seismic data and processing procedures to obtain physical simulation data for analyzing the seismic response characteristics and assessing prediction methods of the reservoirs.The results show that the seismic attribute analysis based on large time windows for platform-margin shoal reservoirs cannot accurately describe the changes of sedimentary microfacies.Instead, the fine interpretation of strata focusing on reservoirs based on geological models does better.With reservoir thickness and property parameters affecting seismic amplitudes, the method works better with amplitudes clearly revealing the physical properties of reef-shoal reservoirs and frequency attributes mapping the reservoir boundaries.

Key words: seismic response characteristics, seismic physical model, platform-margin shoal reservoir, Maokou Formation, Yuanba area, Sichuan Basin
