摘要
应用高分辨率层序地层对比技术在馆陶组砂体细分小层的基础上,以三维地震资料为基础,通过精细层位标定确定储层砂体的地震响应特征,遵循层序对比的原则加密解释到小层,在精细构造解释的基础上,运用波形相位特征、地震属性分析等储层预测技术,综合研究储层发育,确定河道砂体的分布范围,利用叠前属性有良好的保真性和多信息性进行油气检测,应用效果显著。
Based on the subdivision of the sublayers in sandy body of Guantao Group by sequence correlation of strata technology and by using 3D seismic data, the seismic responses of sandy body were defined by fine horizon calibration. Sublayers were interpreted according to the sequence correlation. The reservoir development was studied and the distribution of channel sandy body was defined using reservoir prediction technologies such as waveform phase features, seismic attribution analysis and so on. The hydrocarbon detection was done by prestack attribution with good fidelity and multi-information. The good application results have been obtained.
