The limitation of long-time required to conduct deliverability test, which results in fewer testing, has brought ink-bottle effect on the productivity evaluation in tight gas reservoir. By means of transient seepage equation and optimum algorithm, trial production data is utilized to compute the accurate reservoir parameters, such as permeability etc, which can be substituted in pseudosteady-state flow equation to compute the open flow potential. Strict theory derivation and the result of this method from actual example on-site shows the credibility of this method, which can be reference for other low permeability gas reservoir.
