Braided River Delta Reservoir Prediction Method Study of Denglouku Formation of the Yaoyingtai area in Songliao Basin
摘要
Abstract
[Objective]Braided river delta deposits are developed in Deng 4 sand group of Denglouku Formation in Yaoyingtai area.Due to the thin sand bodies and the consequent difficulty in reservoir prediction,a comprehensive analysis using multiple methods is required to select effective reservoir prediction techniques.[Methods]This study conducts post-stack and pre-stack seismic attribute analyses through integrated examination of seismic data,well-log curves,and drilling records,employing waveform inversion to predict reservoir distribution.[Results]The results show that the frequency-division seismic RGB fusion technique using 15 Hz,35 Hz,and 55 Hz can identify favorable facies belt distributions in the Denglouku Formation of the Yaoyingtai area.The gas-bearing sandstones in the fourth member of the Denglouku Formation in the study area exhibit AVO responses,enabling effective identification of the thickness characteristics and distribution boundaries of the gas-bearing sandstones.The results of post-stack waveform simulation and pre-stack waveform inversion based on sensitive parameters for sandstone lithology and gas-bearing properties indicate that the gas-bearing sandstones in the fourth member of the Denglouku Formation in the Yaoyingtai area are predominantly purple to purplish-red in the frequency-division RGB fusion images,and exhibit Type I,Type II,and Type IV AVO responses.Sandstone development in the northern part of the study area is relatively better than that in the southern part.The gamma-ray curve and the P-wave to S-wave velocity ratio curve can effectively delineate lithology and gas-bearing properties in the area.[Conclusions]The relevant technology can provide a basis for identifying complex continental reservoirs.关键词
