Dynamic prediction models of producers in tight gas reservoirs with low permeability in Daniudi gas field, Ordose basin

Daniudi gas field is a newly discovered tight gas field with low permeability. The working system determined by using conventional dynamic analysis method cannot assure long - term stable gas productioa In order to solve this problem, the percolation mechanisms of low permeability gas reservoirs are studied, and dynamic prediction models of producers in tight gas reservoirs with low permeability are built. Field application gives out a coinci-dence rate of 84%. These models, which are built with conventional data, are simple, easy to use, and convenient for field applicatioa
