To explore the volcanic gas reservoir rationally and efficiently by using horizontal well technology,a simple and analytical method is proposed to demonstrate the influence of pressure loss along the horizontal well on productivity of the horizontal gas wells. The inhomogenous distribution of pressure in the horizontal bore hole of horizontal gas well occurs. Thus,we deduce the computational method of the horizontal gas well productivity for the volcanic gas reservoir and do the numerical resolution,based on mass conservation law and unit force. A variable PE is defined to describe the relative pressure loss. We use the numerical resolution to determine the productivity of horizontal gas well in the volcanic gas reservoir and the pressure loss of the horizontal gas wells.
