Research Of Dynamic Analysis System Of The Reservoir Based On GIS

The work of the oil reservoir’s dynamic analysis is analyzing various changes by the latest materials acquired from a mass of oil-water wells while oil reservoir is being exploring, and integrating them organically to explain various appearances and finding regularity to predict the dynamic change trend and to adjust the direction of excavation explicitly as well as the parts which do not meet the development rules and influence the final development effects. With the production development in oil and gas field, it is inevitably requesting comprehensive and timely analysis on the status of reservoir development cause the serious situation of its high recovery degree, high liquid index and high water. But traditional way of drawing has not been able to meet the needs of the production of the oil field since the growing number of production reservoir wells and growing amount of the wells data. Whereas GIS is the very powerful tool for its ability to store, manage and analyze of various forms of spatial data, it can effectively aid technology development personnel in dynamic analysis of the reservoir with the help of GIS’ability in comprehensive analysis and powerful processing in of all kinds of material, which can make the concealment of the geological law becomes apparent. This article mainly discusses the application of GIS in oil field development. For example, with support of GIS we can design and develop dynamic analysis system of oil reservoir to serve information construction of oil exploration. The combination of GIS and gas development has provided convenient and rapid supplementary methods and means for visualization and intellectualization of oil field development’s decision-making process, thus it also can supply effective means and decision-making basis for oil reservoir management’s decision-making level and the improvement of the enterprises’economic benefits. It helps us to improve the effect of oil development constantly and raise the final oil recovery of oil fields.This paper mainly focuses on the knowledge integration research of the general GIS technology and reservoir dynamic analysis. It develops research on the following aspects.①The basic problem analysis which needs to be solved in the GIS is essential functions and dynamic reservoir analysis. It mainly discusses the basic approaches and solutions of dynamic reservoir analysis in the support of GIS. In addition, in theory it offers the feasibility and necessity of developing dynamic reservoir analysis in the support of GIS. ②The design and development of dynamic reservoir analysis system based on GIS. It realizes the detailed design and planning on the system function. Whereas, it has developed professional application analysis software system which includes the basic data input, output,management, the graphic display, oil field production inquires under the C#.Net development platform. So it can provide decision-making service for oil field production.③For the specific oil field production information; it can solve the problems in production to apply the software in the production of specific analysis.It has stated the aims and meanings of this system development at the beginning of this text. Apart from this, it has also talked about the main content and represented the thoughts as well as technological route of the system research. I have in detail discussed the related requirements of the oil reservoir’s dynamic analysis system based on GIS after briefly introducing the current situation and the future trend of GIS in oil reservoir’s development. Furthermore, I have spread out analysis about the data demand of the system, function demand, key technologies and software and hardware development platform. On the basis of system analysis, I have carried out detailed design of the system in depth. In that design, I have expounded the design’s thoughts and aims of the system and given the general structure of the system framework. In addition, I have finished the detailed database design of reservoir development. In this text, I have introduced the primary functional components of the system and given the functional design of all components and the class structure of their implementation. I have also introduced many other components which are developed to achieve the function of system, such as plan components, single well figure components, section components and3D map components, and explained the methods how to accomplish these components as well as the function which these components can achieve. What’s more, I have conducted a detailed test for the functions that the system can achieve by using the data that is acquired from practical production of oil field.The dynamic analysis system of oil reservoir is an assisted decision-making system that puts the information that comes from the oil recovery enterprise’s gas development into visualization. To some extent, the system is also a management analysis system which is on the base of oil wells’ distribution and regards the production data as core by using computer technology, GIS technology, and database technology to make the dynamic information of oil field visualization, to realize the search quickly and to provide reliable basis for oil field’s daily management and plan. The system with C#.net for its basic development environment puts the self-developmental components named "MapControl" as realizing platform of GIS’ essential functions and regards SQL SEVER as its backend database. It adopts the data organized solution which combines files with database and uses C/S model by the double files’way to manage system data. The essential functions that the system can accomplish are listed as follow:①Data entry, management and maintenance:it mainly includes logging data material, drill logging data material, basic geological data material and oil field production material.②The visualization of geo-spatial data:the way to realize the display of the work area wells’ distributions is developing GIS components (MapControl).The functions of these components include selection, enlargement, reduction, wander, wells’mapping, the drawing of equal-potential surface, the drawing of well logs that pass through well, the drawing of boundary, the inquiry of wells and the settings of style and so on.③The visualization of the single wells’ information:the method of implementing the visualization is developing the single well figure components.its functions are to realize the dynamic performance of the single wells’production, to display well logs and horizons at the same time, and to adjust these curves’layout and style willfully.④The visualization of the wells group’s section:it can be able to visualize the data of wells group, show the group’s production change clearly and adjust these curves’ layout and style willfully by developing section components to accomplish the dynamic performance.⑤The dynamic information’s inquiry with the basis of visualization:production information can be inquired by using the plan components to click target well or choose it with box, and coupled with its special conditions. The inquired results are shown by table or grapy.⑥The statistical analysis of the oil field’s dynamic information:it can calculate and analyze the dynamic information according to the productivity, productive level and other features of oil field. In addition, it can also accomplish the calculation of productive reduction and relative permeability.⑦The establishment and visualization of3D model:it can visually display the3D data and read the model data dynamically to display the varying characteristics of oil reservoir at the longitude and in the plane. What’s more, people can use the mouse or keyboard to do some interactive manipulation which includes revolving, moving, zooming3D objects, ascending or descending the location of lens, revolving the focus of lens and so on.⑧The production and output of graph and table:this part requires to achieve graph and to print it out.According to the practical test and application, it shows that this system is available and effective, and playing a significant role in daily management of oil reservoir. It must be bring best benefits for gas exploration of our china.
