【摘要】 利用地震资料预测地层压力是压力研究常用的方法,但在地震资料品质差,层速度资料失真的情况下,压力预测结果差强人意。为了避免此类问题,一些研究人员提出了利用井约束反演预测地层压力的方法,其结合了地震资料与测井资料的优点,在许多压力预测的研究中得到成功应用。但其不适用于已钻井数量少分布不均匀、且地形横向起伏大的区域。因此,本文提出了利用地质统计学反演计算地层压力的方法,并在渤海黄河口凹陷的研究中取得了良好效果。更多还原

【Abstract】 Formation pressure prediction using seismic data is a common method.But the result is not good with the poor quality of seismic data.Some researchers proposed the method of formation pressure prediction with well-constrained seismic inversion to avoid such problems.This method combines the advantage of seismic data and logging data.It is successfully applied in some research works.But this method is not suitable in some working areas with few wells distributing unevenly and terrain undulation being big.So,this paper proposes a new method of formation pressure prediction with geostatistical inversion.The application of the new method achieves successful result in Huanghekou Sag,Bohai Bay Basin.更多还原
