摘要(Abstract)：

针对含油气泥页岩有机非均质性强的特点,以松辽盆地南部小城子地区青山口组为例,提出利用井震联合反演方法预测有机碳质量分数的空间分布.该方法首先基于改进的Δlg R模型确定井剖面上有机碳质量分数的变化,分析有机碳质量分数与纵波阻抗的相关性;然后根据测井评价和稀疏脉冲约束波阻抗反演数据分别求取垂向和水平变差函数;最后利用井震联合反演得到高分辨率有机碳质量分数数据体.结果表明,该方法可以有效预测青山口组有机碳质量分数空间分布,后验井检验反演结果与测井评价有机碳质量分数符合率达82.7%;参照页岩油资源分级评价标准,研究区青山口组页岩油主要富集于青一段,区域上分布在西部和城10井区.该方法为少井或勘探初期地区泥页岩有机碳质量分数的空间分布预测提供新思路,对页岩油勘探开发具有指导意义.
