Representative Achievements 1、LVIB series portable hydraulic servo vibroseis Seismic source is a necessary part of seismic exploration. Explosive source is limited and other pulse source energy is small. It is of great significance to develop a source suitable for middle and deep exploration. Supported by the project of 863 portable distributed telemetry seismic exploration system during the 12th Five-Year Plan and the research and development project of portable hydraulic servo vibroseis during the 13th Five-Year Plan, we innovatively developed the portable hydraulic servo vibroseis series of self-propelled crawler products. The seismic source has been successfully used in geological survey and three-dimensional seismic detection of urban underground space, and has achieved good application results. Using four LVIB-15 Seismic Vibrators combination, we have successfully obtained 3s reflection records in Songyuan, providing light source equipment for deep seismic exploration. 2、Study on the influence mechanism of soil thermal conductivity "Correlation between characteristic parameters of soil resistivity and thermal conductivity" is an important research content of the Natural Science Foundation in my charge. Through numerical simulation and laboratory experiments, the correlation between thermal conductivity and resistivity of silty clay in Changchun area was obtained. The relationship between resistivity and thermal conductivity was analyzed by scanning electron microscopy (SEM) from the microstructure characteristics of soil samples. It lays a theoretical foundation for the exploration and evaluation of geothermal energy by using electrical method. At the same time, it also provides a theoretical support for the real-time monitoring of the treatment process of thermal desorption soil pollutants by resistivity method. |
