Comprehensive correction method of airtight coring saturation based on core classification

The indoor comprehensive analysis of core saturation airtight coring wells is an important part well logging interpretation. According to the data, geological reserves can be accurately calculated, and remaining oil water-flooded zone in later stage production evaluated. Due influence many factors process experiment process, sum water usually not equal 100%. At present, conventional correction method generally analyze oil-water saturation, then correct data same that affect results. This article combines two methods for XX oilfield China. For cores with consistent missing factors, mathematical statistics are used saturation. When most rock pores have irreducible oil, phase percolation split after experimental analysis. By comparing interpretation results adjacent wells, feasibility verified.
