摘要
震电效应用于油气勘探是一种非常有潜力的测井新方法。为了测量震电信号,搭建了模拟测井实验环境,设计了信号发生电路和功率放大电路。实验结果表明,在含流体空隙介质的岩石样本中,确存在由声波所激励出的震电信号。分析实验所得波形为研究的进一步发展提供了参考结果,针对试验中所包含的不足,提出了改进意见。
The seismic-electric effect applied to the petroleum exploration is a very potential new logging method. A simulated experimental environment has been prepared in order to measure the seismic- electric signal, the circuit of the signal generator and the circuit of the power amplifier have been designed. The results show that the seismicelectric signals excited by sound waves really exist in the rock samples which have saturated pores. The waveforms obtained from the experiment were analyzed, the results were provided for the further research. Aimed at some problems in the experiment, some suggestions are put forward.
