Application Analysis Of Well Test Data In The Development Of Xushen Gas Field

The energydemand、contradiction of supply and demand is increasing seriously with the continuous development of China’s economy, energy security situation is increasing seriously,too.with the development and utilization of natural gas is more and more attention,so the effort in natural gas exploration and development also increasing. The deep gas has got well fracturing because of the great breakthrough of cementing and drilling technology in recent years.Only in 2006 has reached 24.4 billion cubic meters. With Daqing Oilfield put forward target of "steady four to five",the natural gas exploration and development has a span of growth. But with the development of the gas field scale more and more big, geological and production situation of field has become more and more complex, dynamic monitoring and analysis of related work is more important.Therefore, the need for further work of field monitoring and interpretation and evaluation. As in the gas reservoir production management, focus on the development of field monitoring work, related data collection, accumulation, meet the data analysis and dynamic analysis of admission needs, provide useful information for gas field development, so as to achieve a correct understanding of the development of gas reservoirs, the purpose, the pressure buildup test, establishing and solving the model, the method of determining the instability gas well reasonable shut in time mathematical aspects of the understanding.Well testing as an important technology in the dynamic monitoring of gas field development, how in the increasingly complex geological conditions, solve the problems in the development of gas fields problems by using well testing data to discover and engineering and technical personnel, has become the most urgent problem. At the same time, how to make use of contradictions well test data of diagnosis in gas field development has become effective means of inspection well test data. Therefore, the development situation of severe challenges at the same time it also brings opportunities for well test technology, test technology in the continuous solution development contradiction at the same time also gradually develop and improve.This paper summarizes the development process of well test technology, and taking Daqing Xushen gas field as an example, explains the application of well test interpretation of data in the field of dynamic development process in the specific analysis of the guiding roleof different test data corresponding to gas field development process, and combining with the actual production of testing items in the actual interpretation in the process of application this paper put forward a new idea.
