Embodiment Construction

[0020] The technical scheme of the present invention redesigns the shallow water surface excitation mode of the traditional electric spark seismic source, and they are placed in a cone similar to a geophone (such as figure 1 shown), it is called the electric spark sub-seismic source. The structure of the phased array electric spark sub-seismic source is a metal shell 1, the lower part of which is a cone 2, and a high-voltage electrode 3 and a low-voltage electrode 4 are arranged vertically inside the metal shell 1. The high-voltage electrode 3 is connected to the energy system and control system outside the metal shell 1 through a coaxial cable 5. The energy system is composed of a film capacitor insulation structure with high energy storage density and high power density, and the control system is composed of a modular high-current discharge pulse Source and low jitter switch system, it has the function of multi-source sequential accurate discharge control (the energy system ...

Abstract

The invention discloses a phased array spark subsource for seismic exploration, which has a main structure as follows: a metal shell of which the lower end is a cone is provided, and the shell is internally provided with a high-voltage electrode connected with a coaxial cable of a high-voltage power supply; a low-voltage electrode corresponds to the high-voltage electrode and is fixed on the cone; and the opposite electrode ends of the high-voltage electrode and the low-voltage electrode are respectively designed into mutually parallel band electrodes between which electrolyte is arranged. The subsource provided by the invention has a small quantity of water so as not to depend on environmental water. The spark subsource provided by the invention consists of a plurality of subsources distributed in an array way in practical application, the high-voltage electrode and the low-voltage electrode are both arranged in the shell of the spark subsource, and a discharge-in-liquid chamber is formed by a sealed space. The high-voltage electrode and the low-voltage electrode are designed into a parabola shape, and the discharge center is located at the focus of the parabola, thus, most of the generated energy can be propagated to the underground.

Description

technical field [0001] Seismic exploration is widely used in the exploration of mineral resources such as petroleum and coal fields. The commonly used seismic sources in seismic exploration mainly include explosive source, vibrator, air gun source and electric spark source. However, in the mountainous environment, these seismic sources have various defects, which makes it difficult for the seismic exploration of mineral resources to be widely implemented in mountainous areas. The seismic exploration phased array electric spark source of the invention solves the source bottleneck problem of mountainous seismic exploration. Background technique [0002] As we all know, seismic exploration sources mainly include explosive sources, vibrators, air gun sources and electric spark sources. The explosive source is a traditional source. Its disadvantage is that it is necessary to drill a blasthole with a depth of 10-20 meters for filling explosives in the field. This is very difficul...
