Abstract

Abstract:

Absolute open flow capacity of gas wells is a key index reflecting potential production capacity of gas wells.It is usually obtained by systematic well testing.For low-permeability reservoirs,however,it is difficult to define binomial deliverability equation through conventional systematic well testing. Based on analyses of binomial deliverability equation for gas wells and influences of reservoir types and characteristics on deliverability testing data,the modified isochronal testing data of over 20 wells in the Jingbian gas field were used to set up an empirical method for determining deliverability with build-up data.Field application shows that this method is feasible and effective.

Key words: gas reservoir, gas well, deliverability testing, build-up, absolute open flow, the Jingbian gas field
