地震属性分析技术在储层预测中的应用

Application of Seismic Attribute Analysis Technique in Reservoir Prediction

根据目前已发表的文献，地震属性有数百个之多，通常用于地震解释的也有30—50个。地震属性技术作为地震勘探的一项新技术，已经在油田的勘探开发、油气藏的预测与描述中取得了较好的应用效果，它是连接地震信息与储层及油气藏分布的有效桥梁。地震属性分析技术在储层预测中的应用包括地震属性提取、地震属性优化和储层参数转换等技术。地震属性提取包括剖面属性提取、层面属性提取、三维体属性提取。通过吐哈-三塘湖盆地的应用实例分析不难看出，应用地震属性预测油气藏在原理和方法上是可行的，并且具有广阔的应用前景。

There are hundreds of seismic attributes, among which 30 to 50 are used in seismic interpretation generally according to published literatures so far. As a new technique in seismic exploration, seismic attribute technique has obtained good effectiveness in exploration and development, reservoir prediction and description, and is an effective bridge between seismic information, reservoir and hydrocarbon distribution. The application of the seismic attribute analysis technique comprises of seismic attribute abstraction, seismic attribute optimization and reservoir parameter transformation, etc. Seismic attribute abstraction includes profile attribute abstraction, plane attribute abstraction and 3 - D attribute abstraction. Through the analysis of field application in Tuba - Santanghu basin, it is not difficult to find out that predicting hydrocarbon reservoir by using seismic attribute is feasible in theory and methodolgy and has wide prospect of application.
