A new spontaneous potential log model for the case when formation resistivity is not piece-wise constant was introduced. 针对非均质地层中电阻率非分块常数,提出一个新的自然电位测井模型。
The spontaneous potential is closely related to salinity in formation and mud filtrate. 自然电位的形成与地层水矿化度和钻井液滤液矿化度密切相关。
It noted that the concentration of formation water and the cation exchange capacity are the main factors that influence the spontaneous potential. 证明了地层水浓度、阳离子交换量是影响自然电位大小的主要因素。
