Development Of Dynamic Analysis System Of A Gas Reservoir In Changqing Gas Production Plant

Whether from domestic or from the whole world, as a kind of clean and high efficient energy natural gas is becoming more and more important. In our country, proved reserves of natural gas is more and more abundant, the development of natural gas industry is booming. But as a kind of non renewable resources, China’s natural gas reserves are still limited. So how to develop the natural gas reasonably and efficiently is one of the main tasks now.Dynamic analysis of gas field development throughout the whole process, and relates to all aspects of it. Study on the dynamic characteristics, grasp the law of its change is the main and the most basic work of gas field. With the development of computer technology, the cross application in other industries is more and more widely. To use the method of computer analysis of in the process of gas field development, have brought great convenience to the processing and analysis of the huge production data. Use the computer to progress the gas reservoir dynamic analysis of the gas field will be more efficient and accurate. For the shortage of traditional software, the research of this project focused on the dynamic analysis and prediction. Among them, the physical property analysis and the conversion of bottom pressure of natural gas is included, there are four kinds of methods involving. To study how to improve the calculation accuracy of dynamic reserves is the main work of the calculation of reserves. Focus on the pressure drop curve method and its improved method, the decreasing analysis have a comparative study about the characteristics of this three decline ways, including decreasing exponential decline harmonic decline and hyperbolic decline. The prediction model has a comparative study about six kinds of model and applicability of it.By means of analysis the huge experimental data and the comparative study of several methods, to understand and master the dynamic rules in the processing of the gas reservoir development. According to these laws and the results of dynamic analysis, can help us to develop a reasonable development plan and feasible production plan, so as to provide a simple and practical tool of scientifically adjust and develop the gas field.
