Application Of Comprehensive Logging Evaluation Method Of Remaining Oil In Putaohua Layer Of Xingnan Oilfield

After many years’ development, Daqing placanticline Xingnan oilfield has entered intoextra high water cut stage. Remaining oil in layers is the main study object of developmentand adjustment.. Putaohua petroleum reservoir water flooding degree is high for the moment,moreover subsurface profit distribute complex changeable, insufficiently is not deep enoughalso thorough to the reservoir water flooding characteristic.Therefore, The developmentof water flooded layer interpretation technology research foundation, established a welllogging interpretation standard, and research distribution of remaining oil.In this paper, based on the comprehensive analysis of the reservoir characteristic, use ofsealed coring data of inspection wells and production data, the system summed up the loggingresponse characteristics of different types of water flooded zone Xingnan area, through acomprehensive analysis of well logging, In the study of reservoir classification;analysis ofthe conductive mechanism of different petrophysical facies reservoir are established, and theporosity, permeability, saturation of reservoir parameters log interpretation model of waterflooded layer interpretation and logging. The use of radioactive logging and productionmonitoring and logging data analysis of remaining oil saturation, remaining oil distribution,and laid a solid foundation for the future of a series of measures. The project research resultsfor the extra high water cut period of water flooding remaining oil evaluation and furtherdevelopment to provide strong technical support.
