电阻率测井在评价油藏流体饱和度、区分含油气、水层方面是应用最广泛的方法。过套管电阻率测井是目前评价地层含油饱和度的有效方法之一。本文介绍过套管电阻率测井仪器的基本原理、结构及指标,通过对实际测井资料进行综合分析,总结了过套管电阻率测井资料的优势所在,以及该仪器在大庆油田剩余油监测上的应用情况,并针对大庆油田中低渗透储层评价的技术需求进行了积极地探索。
Resistivity logging is the most widely used method for evaluating reservoir fluid saturation and for distinguishing hydrocarbon-bearing and water-bearing layers. Ceshed resistivity logging is one of the effective methods to evaluate formation oil saturation. This paper introduces the basic principle, structure and index of casing resistivity logging instrument. By comprehensive analysis of actual well logging data, the advantages of overhole resistivity logging data are summarized, and the remaining oil in Daqing Oilfield Monitoring the application of the situation, and for the low-permeability reservoirs in Daqing oilfield evaluation of the technical needs of an active exploration.
