针对薄互层储集特点的地震属性优化技术及应用效果

Seismic Attribute Optimization Technique and Application Effect Based on Features of Thin Interbed

利用地震资料属性信息预测油气储层的相关参数已在实践中见到了较好效果,但如何优化地震属性,如何更精确地预测薄砂岩储层特征是地质及地球物理勘探家们不懈的追求。在借鉴主成分分析思想的基础上,提出一种新的地震属性优化方法———约束主成分分析。理论模型计算及油田应用结果表明,该方法不仅能提高储层预测的精度,而且具有更强的适用性。

Good effect has been achieved to predict the related parameters of oil/gas reservoir by using seismic data attribute information,but it is still a continuous pursuit for geological and geophysical exploration experts to predict the thin sandstone reservoir features more precisely.By referring to the idea of main ingredient analysis,a new seismic attribute optimization method is brought forward,that is,constraint main ingredient analysis.The theoretical model calculation and oil field application result show that this method not only can improve the precision of reservoir prediction but also has a stronger adaptability.
