    APPLICATION OF SPECTRAL-INVERSION BASED ON MATCHING PURSUIT TO SEISMIC INTERPRETATION

    • 摘要: 受地震资料分辨能力的限制,薄储层、微小断层等小尺度地质体刻画始终是困扰油田精细勘探与开发的难题之一。基于匹配追踪算法的频谱分解反演技术为提高地震综合解释精度提供了一条新的途径。该技术在高精度频谱分解基础上不依赖于先验模型及解释层位等约束,基于叠后地震数据体可直接反演并得到地震反射系数序列。该数据体具备很高的分辨能力,作为基础数据在地层层序细节刻画、薄储层及小断层等微小地质目标识别等方面具有明显优势。该技术在渤海数个油田中进行应用并取得较好效果,具有广阔的应用前景。

       

      Abstract: Due to the limitation of seismic resolution, small geological objects, such as thin beds and microfaults are difficult to be identified. The spectral-inversion technique based on matching pursuit has been introduced in this paper as an effective way to improve the resolution of seismic interpretation. Spectral-inversion technique can directly acquire reflection coefficient data without any prior model and horizon based on high precise matching pursuit spectral decomposition. The reflection coefficient data can be used for stratigraphic sequence description, thin reservoir prediction and small fault identification with its higher resolution. Actual applications of this technology to several oilfields have shown good results and a wide application is expected.
