摘　　要：随着地震勘探与开发的不断进行,常规油气藏已所剩无几,复杂的隐蔽性油气藏将成为未来油气勘探的重点。储层预测、油藏描述与分析等方向将逐渐取代单一的地震资料构造解释。地震属性分析技术在这些方面是一种快速有效的方法,但对于本区非均质性较强、物性参数变化大的火山岩储层,往往单属性分析多解性强,会影响最终预测的精度。基于此问题,采用多属性融合储层预测方法。首先根据石炭系工区油藏特征,确定合适的时窗(P1区),再对不同类别属性进行相关性和属性特征强度综合分析优选出较敏感的4种属性并进行多元线性回归拟合,最终得到多属性融合属性预测平面图,与实际的勘探工区成果图进行对比,能够很好的吻合有利区位置。With the continuous development of seismic exploration,there are few conventional oil and gas reservoirs left,the complicated hidden reservoirs will become the focus of oil and gas exploration in the future. Reservoir prediction,reservoir description and analysis will gradually replace single seismic data structure interpretation. Seismic attribute analysis technology is a fast and effective method in these fields,but for the study area of volcanic reservoirs with strong heterogeneity and large change of physical parameters,the multiplicity of single attribute analysis is always existing,which will affect the accuracy of the final prediction,a multiattribute fusion prediction method was used to overcome the multi-solution problem. Firstly,the suitable time window (P1 zone) is determined according to analyzing the reservoir characteristics of Carboniferous area,four sensitive attributes were selected through the comprehensive analysis of correlation and characteristic strength of different attributes,and multiple linear regression fitting was performed according to four attributes,and the prediction image of multi-attribute fusion is finally obtained. Compared with the actual image of exploration area,the results well coincide with the location of favorable area.
