摘　　要：利用频谱成像技术将时间域地震数据体转换为调谐数据体,通过其振幅谱可以识别地层的厚度变化。蓬莱A地区已钻的3口探井揭示了该区主要目的层段储层单层厚度较大,常规属性指示储层横向分布广泛,但地震剖面显示储层厚度横向上存在着明显的变化。为了研究该套储层厚度的空间变化,利用Landmark软件开展了大量的有关频谱成像模块参数的试验应用研究,最终通过参数的优选预测的储层厚度经实钻井证实比较准确,为类似地区开展储层预测提供了新的思路。Seismic data body can be transformed into tuning body by spectral imaging technology.The thickness of strata changes can be identified by amplitude spectrum.PL1~3 wells had been drilled in the area of Penglai A area revealed that the single-layer reservoir thickness of the main purpose layer is big,and the conventional attributes indicate that the reservoir widespread,but the seismic section shows that thickness of the reservoir is significantly changed.In order to study the spatial variation of thickness of the reservoir,this paper carried out a lot of test parameters testing about Landmark software,and ultimately through the optimization of parameters of the forecast reservoir thickness of the drilling is precise confirmed,and this method can be used for similar areas to develop the reservoir prediction.
