多属性联合反演方法在桩西潜山地区储层预测中的应用

薄储层的识别一直是地球物理技术预测的难题.在石油勘探中后期地区,为提高储层预测精度,应充分利用已钻井提供的储层参数信息,在横向上利用地震资料提供的反映储层地震反射特征的优势属性分析成果,通过建立已钻井点储层参数与多种优势地震属性之间的函数关系,达到有利储层横向预测的目的.多属性联合反演方法在桩西潜山地区沙四上亚段储层预...

Application of Multiattributes Joint Inversion Method to Reservoir Prediction-A Case Study of Zhuangxi Area

It＇s very difficult to predict the recognition of thin reservoir using geophysical techniques.In order to raise the accuracy of reservoir prediction in the areas reaching an advanced stage,it＇s necessary to make the best of the reservoirs parameters that the drilled wells provide and take full advantage of the optimized seismic attributes analysis results reflecting the reservoir seismic reflection properties that the seismic data provide in the horizontal direction.This paper proposed the multiattributes joint inversion technique to forecast favorable reservoir that established the function relationship of the seismic attributes between the reservoir parameters of drilled wells and several advantages.This technique was applied to predict the occurrence of the upper Es4 favorable reservoir in Zhuangxi area.The results match the macroscopically geologic distribution regulation,and there is a high coincidence degree between the prediction and the drill.
