Abstract:
Seismic exploration is a widely used geophysical exploration technology that can detect underground structures, lithology, mineral resources and other information. This paper aims to study the design of high-resolution seismic exploration instruments. By analyzing the advantages and disadvantages of existing seismic exploration instruments, design requirements are proposed to design a high-resolution, high-sensitivity, and high anti-interference seismic exploration instrument.
Firstly, this paper introduces the basic principles of seismic exploration and differential offset imaging technology, and points out that exploration instruments need to have high resolution, sensitivity, accurate positioning, and strong anti-interference characteristics. Then, the existing seismic exploration instruments, including strain gauges, velocity meters, three-axis accelerometers, and laser radars,
are compared and analyzed, pointing out their strengths and weaknesses in different environments and applications.
Next, this paper selects strain gauges and three-axis accelerometers for detailed design and research. For strain gauges, design requirements are proposed to improve the signal sampling rate, improve the signal-to-noise ratio, and enhance the anti-interference ability. Through optimization in digital signal processing technology, a strain gauge with excellent performance is designed.
For three-axis accelerometers, design requirements are proposed to improve sensitivity, enhance anti-interference ability, and improve frequency response. By optimizing the sensor structure and signal processing circuit, a three-axis accelerometer with superior performance is designed.
Finally, the high-resolution seismic exploration instrument designed in this paper is tested for performance. The results show that the instrument has high resolution, sensitivity and anti-interference ability, can achieve high-definition underground structure imaging, and has high practical value.
Keywords: seismic exploration, differential offset imaging technology, strain gauge, three-axis accelerometer, high-resolution seismic exploration instrument.。
