【摘要】 地震属性的研究和应用贯穿于地震资料解释的各个环节。利用地震属性与反演技术相结合,可有效提高油气储层解释的精度。本文介绍了基于参考标准层的地震属性提取技术,并细致描述了沿层属性的提取方法。将该项技术应用于松辽盆地乾安北地区地震资料解释,通过各类地震剖面对比、合成记录标定、地震属性及振幅包络特征分析等具体技术,预测了该区沉积相和河道砂体及其分布特征,分析对比所得的一些关键成果图件,显示该方法具有良好的应用前景。更多还原

【Abstract】 Study and application of seismic attributes is throughout the each link of seismic interpretation. Combination of seismic attributes with inversion technology is able to effectively improve the precision of oil/gas reservoir interpretation. The paper introduced the pickup technique of seismic attributes based on referential marker horizon and described in detail the pickup method of horizon attributes. The technology was applied to seismic data interpretation in Qian’anbei area of Songliao Basin to predict sedimentary facies and channel body as well as their distribution by correlation of different kinds of seismic sections, calibration of synthetic seismogram and analysis of seismic attributes and amplitude envelope. The resulted key maps gained by analyses and correlations showed the good application prospect of the method.更多还原
