The article is devoted to the study of the potential possibilities of using molecular-electronic sensors of seismic waves for field work using the seismoelectric method to explore the hydrocarbon deposits. The introduction provides an analytical review of the current state of research based on data from science magazines and patents. It is shown that at present, seismoelectric effects are at the stage of experimental implementation into the practice of field work for oil and gas geophysical prospecting. Further in the article, theoretical estimates and results of mathematical modeling of the manifestation of seismoelectric (SE) phenomena in the regions of hydrocarbon anomalies are presented, numerical estimates of the values of the seismic and secondary electromagnetic fields are given. The analysis of the results (on a tank and real gas condensate field) showed that the use of molecular-electronic geophones, which have a higher sensitivity and operate in a wider frequency range (up to 0.1 Hz), allows one to obtain higher signal-to-noise ratio. Thus, it has been experimentally established that the use of molecular sensors for recording seismic electric effects when searching for deposits is more preferable when carrying out field work.
本文致力于研究利用地震波分子电子传感器通过地电方法进行野外工作以勘探油气藏的潜在可能性。引言部分基于科学杂志和专利数据对当前研究现状进行了分析综述。结果表明，目前地电效应正处于油气地球物理勘探野外工作实践的实验实施阶段。在文章后续部分，给出了油气异常区域地电（SE）现象表现的理论估计和数学建模结果，以及地震场和二次电磁场值的数值估计。对结果（在一个油罐和实际气田凝析气田上）的分析表明，使用具有更高灵敏度且在更宽频率范围（高达0.1赫兹）工作的分子电子检波器能够获得更高的信噪比。因此，通过实验确定，在野外工作中寻找矿床时使用分子传感器记录地电效应更为可取。
