| 摘 要： | 由于井间电阻率层析成像方法具有施工方便、成本低、对钻孔无破坏作用且穿透深度也较大等优点，因而得到越来越广泛的应用，在过去几年内对该方法研究的重点在于提高计算效率和改善成像质量，本文从井间电阻率层析成像的基本原理出发，对该方法近年的新进展进行了比较和综述，还介绍了概率层析成像算法的原理，认为今后几年内在此领域内的理论研究重点将是探索有效的反演方法和提高成像质量。

| Abstract: | Because of its low cost, nondestructive features and large exploration area as well as its simplicity in practical application, the crosshole resistivity tomography has been used widely more and more in geophysical exploration. During past years, study of the resistivity tomography has focused on the improvement of the computation efficiency and the imaging quality. In this paper, we first briefly review the principle of the resistivity tomography, then summarize and compare some new methods in this field, with special stress in the principle of the resistivity probability tomography. According to our analyses, we conclude that the theoretical research in the near future will focus on improving the efficiency of the inverse method as well as the imaging quality. |
