摘要
自然电位测井是测量沿井身移动的M电极与固定在地面的N电极之间的自然电位差。本文结合在地质调查中的测井曲线,阐述了怎么利用自然电位与视电阻率曲线来划分咸淡水界面。
Spontaneous potential logging is to measure the spontaneous potential difference between the m electrode moving along the wellbore and the N electrode fixed on the ground.Combined with the logging curve in geological survey,this paper expounds how to use the spontaneous potential and apparent resistivity curve to divide the salt water interface.
