| Abstract: | Analyzes main factors of affecting successful gas testing for gas wells with low permeability. It also analyzes different applicable conditions for different gas testing approaches to select suitable testing method for low permeability gas well. Investigation and research an the problems of failure to obtain absolute apen flaw far the creating of deliverability equation in the process of gas testing has been conducted. A productive prediction model has been established for main gas fields after research to predict the corresponding deliverability while farrnaticm pressure changes for the individual well. During the design of the model,the factors of limited flow rate, wet gas and gay testing time are optimized and the design procedure has been improved. |
