分形理论在储集层横向预测和油气层判断中的应用

复杂的地质现象具有内部自相似特点,因此,可以用分形理论来进行定量预测。介绍了利用地震数据求取面积、关联、振幅3种维数的方法和原理,并通过建立的理论模型和计算3种维数,可以进行储集层预测和油气判断的工作。通过实例分析,表明分形分维技术能够较准确地反映地震波形特征和油气藏本身的变化,是一种比较好的进行储集层预测等工作的方法。

The Application of Fractal Theory in Lateral Prediction of Reservoir and Hydrocarbon Diagenesis

The complicated phenomena of geology have the characteristics of internal self-similarity, so the fractal theory could be applied in them for quantitative prediction. By establishing the theoretic model and calculating three kinds of dimensional numbers,the fractal theory have been used for reservoir prediction and hydrocarbon diagenesis. Through applied examples analysis, it is indicated that the fractal dimension technique can accurately display the characteristics of seismic waves and the variation of reservoir itself and it is a good method for reservoir prediction and hydrocarbon di agenesis.
