Description

technical field [0001] The invention relates to the technical field of geophysical exploration, in particular to a multifunctional transmitter. Background technique [0002] Electrical prospecting is one of the main branches of geophysical prospecting technology. Electrical prospecting is to explore geological structures by utilizing the differences in electrical properties between various rocks and strata in the earth's crust. In electrical prospecting, there are currently four main types of electrical properties or physical parameters of rocks and formations, namely resistivity, magnetic permeability, polarization characteristics and dielectric constant. [0003] As a kind of electrical survey, the controlled source audio frequency magnetotelluric sounding method (CSAMT) has attracted the attention of the industry due to its unique advantages such as high signal strength, strong anti-interference ability, and high resolution. This method uses a controllable artificial fie...

AI Technical Summary

Problems solved by technology

The greater the power, the greater the volume and weight of the generator, and the existing portable alternators cannot be connected in series and parallel

Geophysical exploration is mostly field work, the working environment is complicated, and the heavy generator is very inconvenient to transport, and according to different measurement requirements, it is often necessary to carry transmitters and generators of various power specifications, which increases the difficulty of the survey work

[0006] In addition, with the gradual expansion of the application scope of the controllable source audio magnetotelluric sounding method, the measurement requirements are also more diverse. From the perspective of function and cost, the traditional transmitter power specification is fixed, and the functions that users can realize are single. Practical flexibility is poor, and multiple transmitters must be purchased to meet different needs, and the cost is high
