Product Description

High Resolution Seismic Recorder Seismic Receiver Seismic Method Velocity Geophone Seismograph For Refraction Reflection MASW Seismic Survey

WZG-24C High-frequency seismic instruments are used to record the high-frequency components of seismic waves, allowing for the acquisition of subtle information about underground conditions. In field operations, high temporal and spatial sampling rates are utilized, as well as single sensors, high-frequency sources, and wide-band recordings. In digital processing, various methods to improve resolution are employed, such as deconvolution, noise cancellation, wavelet processing, and coherent noise attenuation. High-resolution exploration techniques have been widely applied in hydrology, engineering geology, and the exploration of metallic deposits. In petroleum exploration, high-resolution seismic profiles are helpful for studying subtle structures and seismic stratigraphy interpretation. 

24channels seismic receivers for data acquisition in seismic exploration. In surface wave exploration, the surface wave method, such as Multichannel Analysis of Surface Waves (MASW), is typically employed to study the shear wave velocity of underground structures and uncover the characteristics of subsurface rock layers.
Arrange 24 seismic gephone on the ground in a certain geometric form, usually in a linear or matrix distribution. Then place a source on the ground or underground to generate seismic waves by vibrating the ground. The source is usually a hammer or vibrator. When the source is excited, the seismic waves will propagate underground and be recorded by 24 seismometers. Each seismometer will record seismic wave signals at different times. The collected seismic data is processed, including denoising, filtering and profile stacking. Use the recorded seismic wave data to perform surface wave analysis, study the propagation characteristics of shear waves underground, and obtain the shear wave velocity of underground structures. Through the formation and interpretation of surface wave velocity profiles, identify the characteristics, interfaces and anomalies of underground rock formations. Evaluate the results of surface wave exploration, combine with geological data and other exploration methods, and assist in interpreting and judging underground structures.
