地震属性不仅在碳氢检测、储层参数预测中广泛应用,而且在沉积环境解释中也得到良好的应用[1]。在530井区克下组油藏地震数据体中提取多种属性。选取对砂砾岩沉积和储层特征反映最敏感的属性进行预测。结合530井区克下组油藏丰富的穿层井资料,预测扩边区有利相带分布及砂体展布规律。利用地震预测和井资料两种方法相互验证,为老区滚动勘探开发提供有利保障。
Seismic attributes are widely used not only in hydrocarbon detection and reservoir parameter prediction, but also in the interpretation of sedimentary environment [1]. Various attributes were extracted from the seismic data body of the Kushixia reservoir in Block 530. The most sensitive properties of glutenite sediments and reservoir characteristics are selected for prediction. Based on the data of well strata in Kezha reservoir in Well 530, the favorable facies distribution and sandbody distribution in the expanding margin are predicted. Both methods of seismic prediction and well data are used to verify each other, which provides a favorable guarantee for rolling exploration and development in the old area.
