spontaneous-potential well logging [油气] 自发电位测井
The pressure interpretation mathematical model is established based on the theory of spontaneous potential logging;
从自然电位测井原理出发建立压力解释数学模型；
So, the investigation depth of spontaneous potential logging is the depth of mud invasion, and relation between spontaneous potential and mud invasion depth may be built.
因此，可以得出自然电位测井的探测深度就是泥浆侵入深度，并可建立自然电位与泥浆侵入深度之间的关系。
While the electrode potential logging has relatively obvious reflection to those coal and strata thereby makes up for deficiency from other logging electrical property parameters in the mining area.
而电极电位测井方法，对该类煤岩层的反映特征比较明显，从而弥补了该矿区测井电性参数曲线的不足。
