Abstract

With the continuous improvement of exploration degree,more and more attention has been paid to low-range structural oil and gas reservoirs.Current methods for identifying low-amplitude structures cannot effectively eliminate low-frequency structural background information contained in seismic data,and cannot accurately identify low-amplitude structures.In this paper,on the basis of de-frequency reduction,the trend decomposition method was used in the search for structural inflection points,and the low-amplitude structure was graphed. Combined with the wavelet decomposition method,the continuity in the large-scale time-frequency domain is good.The inverse transform finally obtains a low-amplitude structure explanatory diagram that eliminates the low-frequency background of the structure.The practical application in the northern part of E Basin shows that the low-amplitude structure identification method based on de-frequency reduction enhances the local micro-structural characteristics,and also makes up for the influence of structural elevation difference and random factors on low-amplitude structures.The purpose of the complete and detailed map is of great guiding significance for the exploration and development of complex oil and gas reservoirs with low structural amplitude.

Key words： low-amplitude structure trend decomposition wavelet decomposition low-frequency background
