Problems solved by technology

[0003] 1) Traditional exploration methods have long cycles, high costs, relatively low field work efficiency, and require more staff and ships in the field construction process
[0004] 2) The anti-interference ability of the traditional geophysical prospecting method is weak, and the requirements for the external working environment are relatively high, especially vulnerable to the impact of waves, which brings a lot of inconvenience to the water surface construction
[0005] 3) The accessories of traditional geophysical equipment are complicated, the mobility of field work is poor, and the resolution of exploration results is low, which is greatly affected by the volume effect
[0006] 4) The traditional geophysical prospecting method increases the error of the exploration depth as the depth increases, and also increases the risk factor of drilling.

Abstract

The invention relates to a deep sea resource detecting instrument and an electromagnetic signal screening method and system, and the instrument comprises a sensor which is used for receiving a natural electromagnetic wave signal reflected by a geologic body to be detected; the amplifying circuit is connected with the sensor and used for amplifying the natural electromagnetic wave signal; the frequency selection circuit is connected with the amplification circuit and is used for screening the amplified natural electromagnetic wave signal to obtain a frequency selection signal of a preset frequency band; and the upper computer is connected with the frequency selection circuit and is used for displaying the frequency selection signal. The sensor is used for sensing the natural electromagnetic wave signal reflected by the geologic body to be detected, the natural electromagnetic wave signal is amplified and screened to obtain the frequency selection signal, and the characteristics of the geologic body can be analyzed to obtain whether resources such as petroleum or natural gas exist nearby the geologic body or not. The detector is small in size, light in weight and convenient for field construction, and has the advantages of large detection depth and high detection precision.

Description

technical field [0001] The invention relates to the technical field of detectors, in particular to a deep-sea resource detector, an electromagnetic signal screening method and a system. Background technique [0002] Petroleum is a mineral resource, known as "the blood of industry". In the process of oil exploration, the oil reserves are calculated and determined according to the degree of exploration and proven conditions. At present, to detect the presence or absence of oil and natural gas at sea, traditional geophysical prospecting methods at home and abroad usually use magnetic methods and artificial seismic exploration methods. However, underwater operations at sea have great limitations, mainly as follows: [0003] 1) Traditional exploration methods have long cycles, high costs, relatively low field work efficiency, and require more staff and ships during field construction. [0004] 2) The anti-interference ability of the traditional geophysical prospecting method i...
