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。
A model of logging response of spontaneous potential and induced polarization potential is established.
建立了自然电位和激发极化电位测井响应模型。
We get that the direct problem of spontaneous potential well-logging is an elliptical boundary value problem with jumping condition on the interface.
得到了自然电位测井正问题是一个在交界面上有跳跃的椭圆边界值问题。
