This paper described a pulse discharge hypocenter system, which can be used to carry out arc pulse discharge and corona discharge. At the same time, an experimental platform was set up, which consists of a pulse hypocenter system, a voltage–current measurement unit, a digital oscilloscope and a seismic detection system. On this basis, the experimental study of arc discharge and corona discharge was...
The technology of portable spark source, independent of surrounding water environment, needs to be developed for some special situations. The transfer efficiency from electric energy to seismic wave energy is the most important factor in this technology. The electrode filled with water was firstly designed to develop the pulsed discharge experiment. The seismic wave generated by pulsed discharge was...
This system includes multiple single-channel electric spark sources, the ARM processor, the host computer, a cross station, and an earthquake detector. The ARM processor transfers signal between the single channel electric spark source and the host computer. The upper computer sends out control commands to the ARM processor based on the information transmitted from the single channel electric spark...
It is of great significance for the research of wind load in energy saving and emission reduction as wind load is one part of the ship total loads. An inland cruise ship is chosen as a research object, the wind loads on the ship including longitudinal and transverse forces and the yaw moment are calculated in wind angle of 0–180° by using CFD method, and then the numerical result is compared with...
According to the navigation characteristics of the inland ship, a multiple-constrained model of minimum fuel consumption is established. Some information collection sensors are amounted on this ship in order to obtain the research data. Through analysis and process of these data, the regression functions between main engine fuel consumption and shaft revolution speed and between ship speed to water...
In pulse power field, high voltage pulse capacitor is used widely, and the capacitor charger is its important primary power supply. At present, the capacitor charger usually uses high frequency switching power supply technology. But increasing charging power will lead the volume of charging power supply system to grow larger. And it is difficult to meet the miniaturization requirement. In view of...
Some experimental results were obtained on rock fracturing without the confining pressure by using pulsed power technology. To study the effects of the stratum pressure on rock fracturing, a stratum pressure simulator with maximum pressure up to 35 MPa were development which can simulate the underground pressure of 3000 m depths. The rock samples were exploited from the sandstone mines and manufactured...
The rock fracturing technology can effectively enhance the reservoir permeability and conductivity of oil reservoir and improve the production of oil and gas. In this paper, high-current pulse discharge on rock fracturing was studied and a high voltage pulsed power supply was developed. The pulsed power supply is mainly composed of a high voltage high frequency charging supply, energy storage capacitors,...
In the past forty years, the supply of metal mineral resources of the buried deep within 500m is becoming more and more nervous, and the majority of metal mineral resources are getting exhausted. The exploration of concealed metallic minerals beyond 500m in depth is the focus of the current metal mineral resources prospecting. This paper mainly introduces the application of artificial seismic technology...
In this paper, a set of underwater plasma vibroseis system was developed, which included three big systems, i.e. charge system, discharge system and trigger system. At the same time, an experimental platform was set up through tketornix digital oscilloscope, seismic detector and desktop computer for collecting and processing data. On this basis, three working stages (breakdown, detonation and spread)...
