神经网络多属性融合技术定量预测砂体厚度和分布
Quantitative prediction of sandbody thickness and distribution via multi-attribute fusion technology in neural network
摘要
Abstract
As oil and gas exploration advances into the deep,the exploration difficulty continues to increase.Particularly for oil fields that have entered the mid-to-late development stages,the identification of thin interbedded sandstone bodies has become a core challenge.While seismic attributes can effectively characterize the lateral distribution of sand bodies,single attributes are insufficient for quantitatively predicting sandstone thickness,and serious multi-solutions exist between multiple attributes.To address this technical challenge,this study proposed a multi-attribute fusion method based on the Back Propagation(BP)neural network.The method selects root mean square amplitude,arc length attribute,and average envelope attribute to construct a nonlinear mapping model,tested with calibration data from 11 wells to practice the quantitative prediction of sandstone thickness.The results show that the correlation coefficient between predicted and actual sandstone thickness reaches 0.93,with errors controlled within 3 meters.The method effectively captures the spatial distribution of braided river,meandering river,and deltaic sandstone bodies in the study area,which will provide an efficient solution for predicting thin interbedded reservoirs in complex sedimentary environments.关键词
