摘要
本文根据井下自然电场的成因、自然电位测井工艺过程以及模拟实验的相似理论，得到了部分空间物理模型的理论依据，按该理论设计制作了模拟实验装置，并进行了不同条件下的实验，最后得到了自然电位与地层电阻率、侵入半径、地层的水淹程度等因素的关系。
Basing on the origin of the spontanous electric field in the well,technological process of SP logging and the similarity theory of the simulated experiment,thispaper obtains the theoretical basis of part space physical model. According to the theory, a simulated experiment device is designed and made,and a series of tests are done in different conditions. In the end,the relation of SP to such factors as formation resistivity invasion radius,formation water-out degree is obtained,and a contrast analysis of experiment results,numerical simulation and practical data is given in this paper as well.
