Embodiment
[0042] An ocean controllable source electromagnetic high-current transmitting device includes a ship-borne part and an underwater part, and the two parts are connected to each other through a 10,000-meter-deep tow cable. The ship-borne part includes a high-power generator, a frequency conversion booster unit and a ship-borne deck monitoring unit. Low impedance transmitting antenna and accessories. Wherein, the underwater towing body is made of corrosion-resistant stainless steel, and a pressure-bearing and sealed launching cabin, a pressure-bearing and sealing electronic control cabin and accessories are installed inside it.
[0043] The ship-mounted high-power generator converts and boosts the 380VAC / 50Hz voltage to 500-3000VAC / 400Hz through the frequency conversion booster unit on the deck, and then conducts long-distance power transmission through the 10,000-meter-deep tow cable, and finally transmits the high-power electric energy to the pressure-bearing seal The subsea d...

The invention discloses a sea controllable source electromagnetic large-current emitting device and a use method thereof. The emitting device comprises a shipborne part and an underwater part which are connected mutually through a towrope with the depth of ten thousand meters, wherein the shipborne part comprises a high-power generator, a frequency conversion boosting unit and a shipborne deck monitoring unit; and the underwater part comprises an underwater towed body, a pressure-bearing sealed emitting cabin, a pressure-bearing sealed electronic control cabin, a neutral buoyancy super-low impedance emitting antenna and affiliated accessories. The use method comprises six operating steps. Compared with the traditional sea controllable source electromagnetic emitting device, the sea controllable source electromagnetic large-current emitting device has the advantages that emitting current and heat-dissipating efficiency are obviously improved, and the signal to noise ratio of an artificial field source signal is obviously increased, so accurate and detailed scientific data are further provided for exploitation of mineral resources, such as petroleum, natural gas, sulfide and natural gas hydrate, stored in below a seabed.
Description
technical field [0001] The invention belongs to the field of geophysical exploration, and in particular relates to a controllable source electromagnetic high-current transmitting device for oceans and a method for using the same, aiming at establishing high-power time-domain and frequency-domain artificial electromagnetic fields on the seabed to study the distribution of seabed mineral resources. Background technique [0002] Since the 1970s, marine electromagnetism has gradually developed into an important means of seabed oil and gas resource exploration and basic geoscience research, and has shown obvious academic value and economic benefits. Geophysical exploration methods for deepwater oil and gas resources mainly rely on offshore seismic methods. Since the marine seismic method is only sensitive to the interface response of the reflective layer, it is difficult to determine the material properties of the upper and lower layers of the layer, and it is difficult to detect...
