Reservoir Seismic Prediction And Application In The Condition Of Thin Interbed

Most eastern oil-bearing of our country are based on the thin interbed which composed by sand and mudstone lithology, the formation lithology and thickness on the lateral changes greatly, the longitudinal ability to distinguish the thin interbed with sandstone and mudstone of seismic waves have direct contact with each layer thickness. From the theoretical model's analysis to establish seismic reflection characteristics of thin interbed with sandstone and mudstone of the thickness of thin reservoir prediction and spatial distribution law, according to the study, in the field high-resolution seismic accessing data have a great significance for theoretical and practical.According to analyze the theoretical model and study the qualitative relationship between seismic attributes and thin thickness, then make sure that the feasibility of thin interbed reservoir prediction used by seismic attribute analysis technology. Through the analysis of the seismic attribute optimization and select the appropriate attributes, then combined with all sorts of reservoir prediction method to predict the thickness of the thin layer,at last analysis the advantages and disadvantages and the applicable scope of various methods. According to the seismic attribute correlation to take a different mode analyzing, then conclude a good processing system for prediction. We Analyzed well logging constrained inversion results and extract the corresponding attributes to study the influence on reservoir prediction results.Integrated the high-resolution seismic and logging data, according to analysis of theory application results, familiar with the precision controlling factors of every method, combined with new ideas of the seismic attribute analysis technology have some guiding significance for getting a high reliability prediction results.
