反Q滤波拓频处理技术在河流相储层解释中的应用

Application of Anti-Q Filtering and Frequency Extension Technology in Interpretation of Fluvial Reservoir

本文探讨了Q的估算方法,通过模型测试和实际资料应用表明,该方法能有效提高资料信噪比及分辨率。X油田L1砂体储层预测效果表明,拓频后资料品质及保幅性与实钻井结果吻合程度较高,为降低油田开发风险提供了重要依据。

This paper discusses the estimation method of Q.The model test and actual data application show that this method can effectively improve the signal-to-noise ratio and resolution of data.The prediction results of L1 sand reservoir in X Oilfield show that the data quality and amplitude retention after frequency extension are in good agreement with the actual drilling results,which provides an important basis for reducing the risk of oilfield development.
