油藏动态资料在小断层地震识别及评价中的应用
|
摘要
小断层的识别与评价一直是地震资料精细构造解释的难点之一。在油田开发的中后期,小断层的识别和封堵性能研究成果是油田开发调整的重要依据。本文将油田开发动态资料与地震资料结合,即应用油田开发动态资料弥补地震资料纵向分辨率的不足,应用地震资料克服油藏开发动态数据解释难以准确定位、描述空间特征的技术局限,开展小断层识别及封堵性能评价研究。研究结果表明,将油藏开发动态资料与地震资料相结合,不仅可以提高应用地震资料识别小断层的能力,评价小断层侧向封堵性能,而且能够提高地震资料在油田开发中应用的深度,为油田开发调整决策提供可靠依据。
Identifications and evaluations of minor faults or their lateral sealing property are the most difficult challenges in seismic interpretation.The identifying and evaluating the lateral sealing of minor faults are important basis for adjustment program in oilfield development middle and later phases.In this paper,reservoir dynamics data have been intergraded with seismic data for this purpose.Therefore,their advantages are adapted widely and their disadvantages are avoided as far as possible.Well dynamics data are used for making up seismic vertical resolution,and seismic data is used for making up shortage of characterizing fault spatial features.The application demonstrates that the integration of seismic data and reservoir dynamics can not only improve the ability of minor fault identification,but also evaluate the minor fault's lateral sealing properties.We believe this process will contribute to the understanding of reservoir geology and provide a reference for oilfield adjustment plans.
