摘　　要：南堡油田发育断块多、断块小、断块内部低级序断层广泛发育,准确认识低级序断层,一定程度上影响着南堡油田的开发水平,尤其是注水开发效果。低级序断层的地震反射特征不明显,易与储层相变混淆,通过单一的地震剖面难以识别。针对上述问题,运用断层成像处理技术、地震属性技术、油藏综合分析以及生产资料验证等地震、地质、测井、油藏多学科综合技术,建立了一套完整的低级序断层解释流程。井震藏一体化技术,可以有效的降低断层的多解性,提高断层的识别精度。对于提高地质认识程度、开发方案的制定与调整、滚动增储增产具有重大意义。Nanpu oilfield develops many fault blocks,small fault blocks,and low-order faults are widely developed in fault blocks.Accurate understanding of low-order faults affects the development level of Nanpu oilfield to a certain extent,especially the effect of water injection development.The seismic reflection characteristics of low-order faults are not obvious,so it is easy to be confused with reservoir phase transformation,and it is difficult to identify by seismic section alone.To solve this problem,this paper uses comprehensive technologies of seismicity,geology,logging and reservoir,such as tomography processing technique,seismic attribute technology,reservoir comprehensive analysis and production data verification,to establish a complete process of interpreting low-order fault.The intergratation of logging,seismicity and reservoir technique can effectively reduce the multi solution of fault,improve the fault identification accuracy.It is of great significance to improve the degree of geological understanding development,and to formulate and adjust the development plan,and to increase reserves and production by rolling.
