松辽盆地中南部中浅层岩性圈闭地震识别技术
|
摘要
松辽盆地南部中浅层包括黑帝庙、萨尔图、葡萄花、高台子、扶余和杨大城子等多套含油气目的层。基于高分辨率、高信噪比和高保真度的叠前时间偏移资料,针对不同的目的层,本文分别或综合应用多种提高岩性圈闭识别可信度的技术,如扶余油层以声波曲线重构地震反演和波形聚类为主,黑帝庙、萨尔图、葡萄花和高台子油层以地震属性分析、频谱分解等技术为主,进行了岩性圈闭的解释和预测,取得了很好的效益。
The mid-shallow layer of southern part of Songliao basin includes multiple sets of oil/gas targets: Heidimiao,Sa'ertu,Putaohua,Gaotaizi,Fuyu and Yangdachengzi etc.Based on high-resolution,high-S/N ratio and hi-fi prestack time migration data and different targets,the paper separately or synthetically used multiple techniques improving the confidence to recognized lithologic traps,for example,seismic inversion reconstructed by sonic curves and waveform cluster is mainly used in Fuyu oil strata,the analysis of seismic attributes and decomposition of frequency spectrum are mainly used in Heidimiao,Sa'ertu,Putaohua and Gaotaizi oil strata,where the interpretation and prediction of lithologic traps were carried out and good results were achieved.
