火成岩储层的综合预测研究

Study on Synthetically Predicting the Storage Layer in Igneous Rock

应用基础资料研究了火成岩储层的地质、地震特征,特别是火成岩内部频率、振幅的变化特征,确定了火成岩裂缝存在时火成岩体频率和振幅的变化特征和一般性规律。开展了利用地震属性对火成岩储层进行预测的研究。应用该技术,预测了北5井区火成岩储层的裂缝发育带,并对储层的有利相带进行了综合预测,其结果得到了钻探的证实。

Some basic data is used to study the geology and seismic attributes of igneous reservoir,especially the changing features of internal frequency and amplitude in igneous rock so as to conform the changing features and general rules of frequency and amplitude in igneous body where igneous rock fracture exists.The methods of seismic arrributes for predicting igneous are studied.Based on this methods,a series of prediction technique for igneous reservoir are established and utilized to predict the fracture-deve...
