渤海湾盆地新北油田馆上段储层预测方法

针对新北油田河流相储层横向变化快、探井少的特点及地震预测河道砂体存在多解性的问题，以地质、测井、地震资料分析为基础，从精确地层标定入手，应用相干体分析进行微构造解释，以寻找各级别大小断层附近的河道砂体为目标，应用多种地震属性参数识别砂体，分析确定振幅属性能敏感地反映该区砂体的边界及变化带，可定性预测砂体分布范围，结合对砂体的初步认识，应用稀疏脉冲波阻抗反演定量预测含油砂体，为寻找有利的勘探目标和新区方案的编制奠定了基础。

Techniques for Forecasting the Upper Member of Guantao Formation of Xinbei Oilfield in Bohaiwan Basin

In view of the characters of rapid changes of fluvial sands and less exploration wells and the problems of multi-solutions to forecast channel sands, prediction techniques were researched in Xinbei Oilfield. Based on seismic data analysis and starting from accurate seismic horizon calibration, fine structure interpretation is made by coherence analysis. In combination with geological conclusion, channel sands nearby faults are identified, amplitude extraction analysis and sparse spiking inversion are used t...
