储层地震属性优化及属性体解释

地震属性与所预测对象之间的关系十分复杂。不同工区和不同储层有不同的敏感地震属性;同一工区、同一储层不同预测对象对应的敏感地震属性也有差异。为此,引入了地震属性优化及属性体解释方法。文章论述了地震属性优化的基本原理,简要介绍了其优化方法,给出了两个地区、两种预测对象、4种优化属性体解释的实例。

Seismic attribute optimization and attribute volume interpretation of reservoir

The relation between seismic attributes and objects to be forecasted is very complex. In different areas andreservoirs sensitive seismic attributes are different .The sensitive seismic attributes vary with objects even in the samereservoir and area. Hence we introduced a seismic attribute optimization method and an attribute volume interpretationmethod. These basic principles of seismic attribute optimization are discussed and an optimization method is simplyintroduced. A case study of attribute interpretation containing two areas, two predicting objects and four optimized at-tributes volumes was given.
