Development Of Visualized Software For Data Preprocessing Of Marine Controlled-Source Electromagnetic Method

With China walking into a new five-year plan, the demanding for exploration and production of new green energy sources. Not only the traditional wind energy,tidal energy, geothermal energy are very useful, but also many unknown new green energy which exist in ocean are very useful such as petroleum and natural gas hydrate.A method named Marine controlled source electromagnetic(MCSEM) can effectively be used in the exploration of deep seabed geological structures. Because deep seabed LPG or natural gas hydrate and the attached electromagnetic seabed deposits are quite different to other media, so the marine controlled source electromagnetic method is skilled in precisely to provide a strong theoretical support for deep sea oil and gas exploration.Nowadays, at home and abroad have been taking part in deep-sea exploration.Both the mature theory and proprietary exploration equipment are important.Meanwhile, the method of processing collected data and the method of weakening ambient noise is also very important. Above all, the results of data processing determine the accuracy of detection of the exploration area of valuable mineral deposits.At present, the situation of our marine controlled source electromagnetic data processing is in a low efficiency, low degree of integration, and lack of visual interface. The design of software is based on the MFC framework of using the factory model, using the C++ 11 language, has developed a marine controlled pretreatment source electromagnetic data visualization software. This software make full use of the Standard Template Library(STL), so simplify development effort and the use of multi-threading technology helps to improve processing efficiency. The main features of the software include: loading and electromagnetic field data navigation and playback data, electromagnetic data domain to frequency domain conversion, and navigation data to generate frequency domain data consolidation and MVO and PVO curve, automatic interaction of positive and negative results of preprocessing speech.In all, this software has friendly interface, easy operation, processing high efficiency.Finally, the use of software developed for a certain area of our measured data processing, to verify its usefulness and validity of the results, achieved good application results.
