摘要: 东营凹陷深部储层是干燥沉积环境下的一套红层,其中的孔一中储层厚度大、钻遇井少,具有较大勘探潜力。但目标区地层结构复杂,埋深从南到北逐渐变大,井震关系一致性不好,储层预测有很大难度。通过综合分析井震特征、优选地震属性、建立井震厚度关系,使用单一最佳属性法、多元线性回归法、基于学习型的非线性储层预测法,得出以下认识与结论:1)研究区红层具有薄互层典型特征,频率较上覆和下伏地层高,地震反射具有中振、低连、低信噪比特征;2)新研发的基于优势频率的流度因子具有最好的厚度相关性,最大振幅、均方根振幅、过零点数、能量半时也较好;3)无论是多元线性回归还是非线性支持向量机,优化的五属性储层预测效果要好于七属性;4)基于交叉验证的支持向量机方法十分适合深部储层小样本储层厚度预测,效果好于单一最佳属性法和多元线性回归法。
