The vibration execution part comprises a first hydraulic cavity and a second hydraulic cavity; the first servo valve comprises a first control port, a first liquid inlet and a first liquid outlet, the first liquid inlet is communicated with a liquid source, and the first liquid outlet is communicated with the first hydraulic cavity; the second servo valve comprises a second control port, a second liquid inlet and a second liquid outlet, the second liquid inlet is communicated with the liquid source, and the second liquid outlet is communicated with the second hydraulic cavity; the control assembly is electrically connected with the first control port and the second control port, and the control assembly is used for controlling the opening degree of the first servo valve and the opening degree of the second servo valve. A double-valve-body structure is adopted, the odd harmonic distortion degree is reduced, the deep geological structure recognition precision is improved, and technical support is provided for high-resolution oil and gas reservoir exploration.

The invention provides a spectrum inversion high-resolution processing method based on strong axis stripping, and relates to the field of seismic exploration, and the technical scheme is that the spectrum inversion high-resolution processing method based on strong axis stripping is characterized by comprising the following steps: inputting original seismic data, and extracting strong reflection wave event seismic data; subtracting the extracted strong reflection wave event seismic data from the original seismic data to obtain seismic data after strong reflection suppression; replacing the original seismic data with the seismic data subjected to strong reflection suppression, and establishing a spectrum inversion objective function; and solving the spectral inversion objective function to obtain a high-resolution seismic section which suppresses strong reflected waves and highlights weak signals. The method has the advantages that a spectral inversion high-resolution processing mechanism based on strong axis stripping is clear, and time domain iteration deconvolution stripping of the strong reflection wave event, spectral inversion high-resolution processing stripping of the strong reflection wave event, strong reflection suppression and spectral inversion high-resolution thin layer recognition are involved.

This invention discloses a geothermal detection device for geological exploration, comprising multiple symmetrically arranged hydraulic cylinders. Each hydraulic cylinder has a hydraulic adjusting rod slidably and sealed at its upper end. A drilling support is mounted on the upper end of the multiple hydraulic adjusting rods. A pressure sleeve is centrally and rotatably inserted into the drilling support. A drill rod is inserted into the lower end of the pressure sleeve. A soil-discharging auger is mounted on the outer wall of the drill rod, and a drill bit is mounted at the lower end of the drill rod. This invention increases the detection depth through multi-stage drill rod connections and uses a fixed communication connection between the multi-stage drill rods to enable unobstructed, direct, and accurate detection of the designated area. It is more reliable, has a simple structure, is easy to operate, and can achieve accurate geothermal detection at multiple depths.
