摘要
针对复杂地质区域薄储层预测的难题,以民东地区泉头组一段研究为例,应用低频补偿、高频恢复构建拟波阻抗曲线的方法重新构建拟波阻抗曲线,同时,通过测井曲线标准化、子波标定及地震合成记录、地质模型建立等重要环节,最终实现了民东地区泉头组一段储层预测。结果表明,该方法下的反演结果能够识别出6m左右的薄砂岩,同时结合沉积地质认识,刻画了泉一段砂体的空间展布,为储层预测可靠的分析依据。
Thin-layer reservoir prediction is the main research object and the difficult point in seismic prospecting.With the research of the first section of Quantou Group in Mindong area,the methods of low frequency compensation and high frequency recovery are used to reconstruct pseudo-acoustic curve.At the same time,reservoir prediction of the first section of Quantou Group in Mindong area is finally accomplished with important links of standardized processing of logging curves,calibration of seismic wavelet,synthetic seismogram and geological modeling build.After reconstructing,the result can be identify sand body more than 6m.Combined with the knowledge of sedimentary geology,the spatial distribution of the Quan-I segment sand-body is described,which is seen as the analysis proof of reliability of reservoir prediction.
