The Research And Design Of The Control Software On Marine Multi-Cable Based Seismic Acquisition System

As China's rapid economic development and the continuous improvement of living standards, continued growth in oil demand. The grave situation of oil shortage has become increasingly serious threat to China's national economy development and national energy security strategy.In order to develop the exploitation of offshore oil and break the foreign monopoly, the National 863 high-tech research program in 2001, research project with independent intellectual property rights of sea exploration equipment . After several years of hard work, China's offshore oil exploration technology have made tremendous progress, and obtain a number of valuable information on seismic data in sea trials. In the success of a single cable with two-dimensional exploration of the technology, offshore oil and gas exploration will be moving in the direction of high precision and three-dimensional exploration and development, My thesis is based on this research background."Eleventh Five-Year" special issue 863 "high-precision seismic exploration technology" sub-topic "high-precision marine seismic acquisition engineering machine" will be implement the largest acquisition program in support of 16 multi-cable seismic acquisition system. The control software is an important part and the main control system of the subject. It build a data management platform for system, based on the platform it achieved the overall control, data management and quality control functions and make system integration flexible. In addition, the software control system with good stability, flexibility and scalability. This article is divided into eight chapters, the main contents of each chapters are as follows:The first chapter is devoted to the topic of the paper background, three-dimensional seismic exploration methods, as well as the significance of this thesis research and content.Chapter II introduces the general requirements, the overall program, as well as the introduction of functional nodes of the high-precision cable seismic acquisition system. Chapters III and IV, respectively, introduce from the overall and partial detail of the design process. The third chapter introduces the overall design of the software, as well as the overall modeling. Chapter IV introduced the structural design of the core layer, application service layer and communication layer, as well as all the detailed design of the internal modules.The fifth chapter describes the system design data management platform. The data management software platform through the support of service bus, achieved the dynamic integration of the system and system good management of the complexity data. So the control software can play a better control and management center role in the whole system.Chapter VI introduces the key technologies in software. Including software multiplexing, multi-threaded parallel processing techniques, as well as realization of the GUI, the service-bus communication and graphic optimization methods.Chapter VII introduces tests and experiments. First introduced indoor testing, and then focuses on the numbers of tests in Bohai Sea last year in May to July, as well as the tests in the South China Sea in November. Then give the test results.Chapter VIII summarizes this paper, give my work in the project, as well as the bright spot in this paper. At the same time, prospects for future work.
