Research On Oil And Gas Pipeline Accident Emergency Rescue System Model Based On Web GIS

With the development of oil and gas industry, the number and length of various oil and gas pipelines are increasing. Whether the old or new pipelines, there are various risk factors during operation: construction and material defects, design flaws, corrosion, third-party damage, geological disasters, misuse and so on. Once one or several factors led to the pipeline failure, the accident of leak, rupture, fire explosion and so on will occur. Pipeline accidents not only affect the normal operation, resulting in energy waste and economic loss, but also because of the transmission mediums's polluting and dangerous, can also cause environmental pollution and enormous loss of life and property.Therefore, to enhance oil and gas pipeline emergency rescue system research has important social relevance.Oil and gas pipeline emergency rescue and emergency decision-making process not only need the cooperation of lots of departments and personnel at all levels, but also need the support of the numerous geographic spatial data of pipeline and object.So modern information management tools and methods must be used.GIS can offer an suitable research methods and tools for the decision-making of oil and gas pipeline accident emergency rescue.Under the guidance of the theory of the oil and gas pipelines accident emergency rescue, this paper discussed that how to make use of GIS method to carry out the design, research and development of the oil and gas pipeline accident emergency rescue system whose objective is to control the risk of oil and gas pipeline accident and to prevent the happen of oil and gas pipeline accident and reduce the loss.After deeply studying the system of oil and gas pipeline accident emergency rescue system and the basis principle, technique characteristic, architecture, mode of WebGIS, we set the structure scheme of the oil and gas pipeline accident emergency rescue system based on the software production of ArcGIS, and use the technique of ASP.NET and the C# language to develop the oil and gas pipeline accident emergency rescue system. The detailed research work of this paper is listed as the following:(1) Deeply studied the related knowledge of the oil and gas pipeline accident emergency rescue, such as conception, basic principles, process and main content etc,and it laid a theoretical basis for the research and development of oil and gas pipeline accident emergency rescue system.(2) Deeply studied the related knowledge of WebGIS, such as system structure and mode etc, and it laid a technical basis for the research and development of oil and gas pipeline accident emergency rescue system.(3) Choosing ArcGIS which is one of products of ESRI, Inc. as our developing platform, set the structure scheme of the oil and gas pipeline accident emergency rescue system, introduced the making measure of electronic map based on ArcGIS Desktop,data Organizing based on ArcCatalog, data importing based on ArcSDE, map service creating based on ArcServer,and also introduced the key technique of WebGIS developing, such as ASP.NET, C# etc.(4) Designed system developing platform, system structure, function mode, database etc. based on the characteristic of oil and gas pipeline accident emergency rescue system. (5)Finally, developed the oil and gas pipeline accident emergency rescue system using the technique of ASP.NET and softwares of ArcServer, ArcSDE, Microsoft SQL Server 2000 etc,and applied to the pipeline of FuShun——BaYuQuan which has improved the security of oil and gas pipeline management and rescue decision-making capacity.
