地震相分析在石南21井区沉积相划分中的应用

地震相分析技术忠实于地震信 息本身,克服了地震反演技术的某些缺陷,是研究沉积相和储集层预测的重要手段之一。地震相分析技术大致分为三类,其中基于波形的地震相分析技术综合利用了地震信号的各种信息,具有独特的解决问题的能力。利用Stratimagic地学软件包基于波形的地震相分析技术对石南21井区头屯河组的沉积相和储集砂体的展布进行了研究,取得了较好的效果。

Application of Seismic Facies Analysis to Classification of Sedimentary Facies in Shinan-21 Well Block

Seismic facies analysis true to self seismic information could overcome some shortcomings from seismic inverse technique as one of important means for sedimentary facies research and reservoir prediction. It can be divided into three types, of which waveform-based seismic facies analysis may integrate with various information of seismic signals and can be adopted to deal with distinct problems. Such an analytical technique based on Stratimagic Software Package has been applied to study of the sedimentary facies and buried sandbody distribution of Toutunhe formation in Shinan-21 Well Block, and good results have been obtained.
