川东北普光地区雷一段储层地球物理特征及其地震正演模型分析
Geophysical Characteristics and Analysis on Seismic Forward Modeling of Leiyi Formation Reservoir in Puguang Area
摘要
Abstract
The carbonate reservoirs in the Leiyi Formation section of the Puguang area in northeastern Sichuan are characterized by thin thickness,multiple layers,low porosity and permeability,and high difficulty in seismic prediction.The geological model of wedge reservoir is established based on logging geophysical data.Subsequently,the forward simulation in section shows:When the reservoir thickness is less than 8m,it shows a weak amplitude anomaly in the forward profile,and the amplitude anomaly gradually decreases with the increase of the thickness;However,when the reservoir thickness is equal to 8 m,the seismic amplitude of the reservoir is suddenly enhanced abnormally,and the seismic reflection features of bright spots are displayed on the profile.With the increase of the reservoir thickness,the corresponding seismic amplitude becomes stronger.Obviously,although thin reservoirs are developed in the first member of Lei Formation in the study area,such thin reservoirs also have seismic responsive.This study provides a certain insight for the examination of reservoir seismic response in the first member of Lei Formation in Puguang area.关键词
