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。开展了火成岩储层预测方法技术研究，包括瞬时信息技术、切片对比技术、曲率分析技术、多参数分析法和吸收系数法等，建立了一套火成岩储层预测技术系列。应用该技术系列，预测了S741 块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 for predicting igneous reservoir are studied, including instantaneous information technique, slice comparison technique, curvature analysis technique, multi-parameter analysis method and absorption coefficient method. Based on these methods, a series of prediction techniques for igneous reservoir are established and utilized to predict the fracture-developed zone of S742 igneous reservoir. Some favorable facies belts of the reservoir are predicted and proved by exploration drilling.
