根据沾化凹陷南部罗151井区的火成岩储层特点，提出了适合该区的信息评价方法。利用测井和垂直地震剖面(VSP)资料对地震剖面进行联合标定，可以准确地标定出火成岩的顶、底地震反射层。根据测井和地质资料，选择了对火成岩储层反映敏感的有效地震属性，并利用神经网络储层预测技术预测了本区火成岩储层空间的分布形态。资料对比表明，本区火成岩储层的有利分布范围在构造高点附近，并受构造运动的张应力的影响，在断裂带附近还可以形成裂隙储层。

According to the reservoir characteristics of igneous rock at Luo-151 well, appropriate methods are applied to evaluate the information of this region. The analysis shows that the top and base seismic reflectors can be tracked accurately by calibration of well log and VSP data. The effective seismic attributes selected by combining log and geological data are sensitive to igneous rocks. The spatial distribution of reservoir in this area is predicted with artificial neural network reservoir prediction technique. The data comparison shows that the favorable zone of this igneous reservoir is near the top of the structure, and a fracture reservoir can be formed near the fracture zone due to the influence of structural stress.
