摘要
井间电阻率层析成像技术是从一个井孔向地层发射稳定的直流电流,在地面或另一井孔接收,测量地层电阻率,是井中物探技术的前缘课题,具有广阔的应用前景,近年来出现了许多新的方法。本文从井间电阻率层析成像的原理出发,介绍和比较了井间电阻率层析成像的几种实现方法,如佐迪法、电流线追踪法、模拟退火法和遗传算法等,并且分析了今后井间电阻率层析成像的发展方向。
Cross--borehole resistivity tomography is a technology that transmits a direct current from a point source in a borehole to a resultant point on the surface or in another borehole. The potential difference between the two points can be then calculated. The method is developing rapidly in recent years. In this paper, we review the principle of the cross--borehole resistivity tomography firstly, and then introduce and compare some methods such as Zohdy method, electric current tracing method, simulated annealing method and genetic algorithm method in this field. Finally, we analyze the prospect of the cross--borehole resistivity tomography.
