中文摘要: |
本文针对小尺寸的砂岩模型井,在实验室内建立了动电测井的实验探头和实验测量系统,进行了声波测井和动电测井的实验测量研究工作。记录到了单极源在井中激发的声波信号以及声波传播时诱导的动电转换信号,分析了井中动电信号的传播特性。此外,我们还在实验模型的基础上进行了声波/动电测井的数值模拟研究,并将模拟结果和实验测量结果进行了对比,两者吻合很好。本文研究验证了动电测井理论模拟和实验测量结果的正确性,以及动电测井方法的可行性。 |
英文摘要: |
In this paper, acoustic well logging and seismoelectric well logging experiments are conducted in small boreholes with home-made logging detector and measurement system in the lab. Then the time domain acoustic and seismoelectric signals generated in boreholes are recorded, their propagation characteristics are analyzed as well. In addition, we also simulate the full waveforms of acoustic and seismoelectric well loggings based on the electrokinetic theory, and compare the results with those obtained from the experiments. The results show that they agree well with each other, which verifies the validity of seismoelectric theoretical and experimental results. |
