摘要/Abstract

摘要： 油藏渗流场的变化造成了地球物理参数的变化。对于注水开发油田，油藏中油水之间的赋存形式从原始油藏的平衡状态转变成注水开发过程中的相互渗流状态再到注水压力稳定时的再平衡状态。其间渗流场变化造成地球物理响应的变化不仅仅是流体或者某一单一因素的变化，而是一个综合效应，地球物理响应的变化恰恰表征了渗流场的变化。基于岩心、测井、地震等不同尺度数据间相互关系的分析，提出了多尺度动态岩石物理分析方法；重新定义了渗流强度，探索了油藏渗流场地球物理表征方法。通过对研究区油藏渗流地球物理事件的综合研究，利用该方法较好表征了研究区流场强度，为后期引流、限流方案部署、渗流场综合调整提供了依据。

Abstract: Changes in the flow field of oil reservoirs cause variations in geophysical parameters. Especially in oilfields with water flooding development, the mode of occurrence between oil and water in reservoirs changes from the balance state of primary reservoir to the mutual flow state during water flooding development, and then to the rebalance state when the water injection pressure is stable. During this period, the change of the geophysical response caused by changes of the flow field is not only the change of fluid or a single factor, but a comprehensive effect. The change of the geophysical response just represents the that of the flow field. Firstly, this paper discusses the relationship between the core, logging and seismic data of of different scales, proposes a multi-scale dynamic petrophysical analytical method, redefines the flow intensity, and explores the geophysical characterization methods of the flow field of reservoirs. Through comprehensively investigating the geophysical events of reservoir percolation in the study area, the paper uses this method to well characterize the intensity of flow field in the study area, which provides a basis for the later deployment of drainage and limited-entry schemes and the comprehensive adjustment of flow field.

Key words: flow field, multi-scale, dynamic model, time-lapse seismic, flow intensity
