摘要
在用引进的3700数控测井仪进行碳氧比测井时,对于孔隙度低于25％的砂岩地层,应用阿特拉斯公司提供的硅钙比曲线校正公式,可导致结果的严重误差。为此,我们根据阿特拉斯公司的实验曲线,回归一个新的校正公式。新的校正公式适用于孔隙度小于25％的陆相沉积砂岩储集层,并可较准确地计算剩余油饱和度。
The correction equation for silicon/calcium curve provided by Atlas could cause serious error in sand formations where porosity is lower than 25%. A new correction equation has been regressed on the basis of Atlas experimental curves. This equation is suitable for continental sedimentary sand reservoirs whose porosity is lower than 25%, and a more accurate residual oil saturation can also be determinated.
