模拟地层条件下含水岩石的复电阻率实验研究

Experimental study of complex resistivity of patial-water saturated shaly sands under reservoir condition.

文章研究了泥质砂岩在模拟地层条件下驱替时的复电阻率特性。当含水饱和度增加时,低频和高频复电阻率的模的差值呈单指数减小,但是低频和高频的模的比值和差比(频散度)线性增加,后两个参数与含水饱和度之间的关系与传统的认识不同。

The complex resistivity of patial-water saturated shaly sands has been investigated under reservoir condition. When the water saturation increases, the difference between the modules of the complex resistivity at low and high frequencies decreases exponentially, the ratio of the module at low frequency to that at high frequency, and the percent frequency effect increases linearly. The relations between the water saturation and the later two parameters are different to the traditional results.
