测井解释小层含水饱和度算法研究

Calculation of Subzone Water Saturation by Logging Interpretation

针对储量计算中测井解释小层含水饱和度的计算问题,用Excel宏命令和函数实现了含水饱和度孔隙体积平均计算方法、含水饱和度极值算术平均计算方法、含水饱和度厚度极值平均计算方法以及含水饱和度孔隙体积极值平均计算方法的功能。讨论了各种计算方法的依据及优势,认为含水饱和度孔隙体积极值平均计算方法是4种算法中较为完善的计算方法,具有一定的应用价值。

In consideration of the problems in logging interpreting subzone water saturation for reserves calculation, Excel subroutine and functions are used to implement the methods of average calculation of pore volume of water saturation, saturation extreme and water saturation extreme and the extreme of pore volume of water saturation. The bases and advantages of each method are discussed. It is considered that the method for calculating pore volume extreme of water saturation is the most perfect one in the 4 methods. It is feasible for application.
