地震属性在高精度三维地震解释中的应用
|
摘要
随着油气勘探开发的不断深入,利用地震属性研究储层的技术得到了广泛应用。文中利用高精度三维地震叠前时间偏移数据体,在精细地层小层对比、整体解剖精细评价的基础上,针对目标层段内的砂泥岩薄互层砂组进行了多种地震属性的处理分析及试验,形成了一套多体多属性地层追踪及快速高效的储层描述方法。利用此技术在东濮凹陷马厂高精度三维地震资料解释中,不仅从整体上描述了储层的空间展布,而且利用丰富的地层信息描述了小断块内储层的分布特征,为断块油气藏开发提供了有效的手段,取得了显著的效果。
Along with the development of hydrocarbon exploration and exploitation, seismic attributes have been widely applied in reservoir studying. Based on small layer contrast and precise evaluation, aiming at thin interbedded sandstone and mudstone in the target section, this paper discusses a variety of seismic attribute analysis and test of processing by utilizing high precision 3D PSTM data volume. A suit of techniques for fast formation pursuit and quick and efficient reservoir description with multi-volume, multi-attributes is formed. The technique was successfully applied in high precised 3D seismic data interpretation in Machang Area of Zhongyuan Oilfield. It can not only describe reservoir's space distribution in macroscopic, but also describe reservoir's characteristics within small faults based on plenty of formation information, which provides an effective measure for faulted reservoir's exploitation. Distinct effects have been obtained.
