New Equations for Determination of Non-Resistance Flow in Gas Wells

Abstract

Abstract: According to equations for stable gas well productivity, and considering some key parameters affecting a gas well productivity such as formation pressure, formation factor and permeability, this paper proposed functional relations between the non-resistance flow in a gas well and these parameters respectively, and established correlated curves by using a lot of well testing data from Changqing gas field, obtained three new equations for non-resistance flow of gas wells by linear regression analysis. Case calculations show that these equations are simple for application and reliable for results.

Key words: gas well, non-resistance flow, formation pressure, formation factor, permeability, well testing
