Abstract

Abstract: Gas development practices and laboratory experiments show that there is starting pressure phenomenon in gas seepage in low permeability water-bearing gas reservoir. Therefore, it is very important to study the influence factors and change rules of starting pressure gradient in gas reservoir development. Through experimental methods, the change law of starting pressure in gas seepage in low permeability water-bearing gas reservoir was studied, the correlation analysis of this parameter with water saturation and reservoir permeability was carried out, and quantitative characterization method of starting pressure gradient was researched. An applied analysis was carried out on a typical reservoir with the starting pressure gradient calculation method and gas reservoir percolation theory. Effective development radius of wells was calculated, and the relationship of effective development radius with water saturation and reservoir permeability was established. This method provides a technological guidance for the similar gas reservoirs development especially on well pattern deployment in the early period and well pattern infilling in the middle and later periods.

Key words: water-bearing gas reservoir, non-Darcy flow, starting pressure gradient, experiment research, quantitative characterization
