Analysis And Application Of Sensitive Parameters In The History Fitting Of The Typical Gas Reservoir In The Su Southeast Area

Due to the heterogeneity of the typical gas reservoir and the uncertainty of the reservoir parameters in the Su southeast area,it is difficult to accurately determine the adjustable parameters of historical fitting and their range of values.Therefore,it is necessary to extablish a set of historical fitting method suitable for typical gas reservoirs in the Su southeast area.Firstly,this paper analysised the adjustable parameters in the historical fitting.The adjustment range of adjustable parameters was obtained by single factor analysis and the main control parameters of each development index were obtained by multivariate analysis.Then based on the conclusions obtained by experiments,this paper combined with the production of dynamic data for history matching,completed the error analysis and countermeasure research on history fitting and summarized the historical fitting method of the Su southeast area.Finally,study the stable production capacity of the Su southeast area and reasonably optimized the production index on the basis of the high precision model obtained by historical fitting.Through the research,this paper obtained the adjustment range of adjustable parameters and the main control parameters of each development index,completed the error analysis and countermeasure research on history fitting,summarized the historical fitting method of the Su southeast area,provided effective guidance for the historical fitting of similar gas reservoir.
