Abstract

The invention discloses a water area electric prospecting system comprising a main control platform, a multi-channel receiver, a transmitter, an underwater towed detection cable, and multiple electric field sensors. The main control platform is connected with the multi-channel receiver, and the transmitter is connected with the multi-channel receiver. The electric field sensors are installed on the underwater towed detection cable, and the underwater towed detection cable is connected with the multi-channel receiver and the transmitter. The water area electric prospecting system is used for completing electric prospecting of freshwater areas and measuring geo-electric parameters which can reflect the properties of rock, such as lithology, composition, porosity, fracture degree and water saturation. The technical problem that structural fracture zones, lenses, caves and other bad geological phenomena are hard to find through the existing dot prospecting is solved effectively. The water area electric prospecting system provided by the invention can assist in water prospecting to improve the reliability of water drilling.

Description

technical field [0001] The invention relates to the technical field of water area geological prospecting, in particular to a water area electrical prospecting system. Background technique [0002] In recent years, long-distance pipelines have frequently crossed large rivers (such as the Yangtze River and the Lancang River, etc.), and the geological conditions of the crossing sections have become increasingly complex. A single drilling method is difficult to meet the status quo. It is necessary to adopt multiple exploration methods and strengthen the application of comprehensive geophysical prospecting methods in water areas. The development direction of underwater geotechnical engineering survey work in water areas is also the most effective technical means to solve the geotechnical engineering survey of large river crossings. However, water drilling exploration is subject to natural conditions and human factors. Therefore, at present, water drilling is only point-like explo...
