saturation exponent n (vs) depth curve is given through electmagnetic propagation tool (ept) and microspherical focused log (msfl), from which the changes of wettability with depth will be forecasted.
同时使用电磁波传播测井和微球形聚焦电阻率测井求出饱和度指数随地层深度的变化曲线,预测储层的润湿性。
dual laterolog a focused log that records deep and shallow resistivities.
