| Abstract: | A mathematical model for production rate analysis in horizontal gas well has been established by using the constant gas seepage principle. On a basis of solving the mathematical model, a binomial productivity equation is derived for horizontal gas well. At the same time, effects of various factors on productivity are further studied, including horizontal well length, gas reservoir thickness, gas reservoir anisotropism and formation damage, and correspondent inflow performance relationship(IPR) curves are plotted. These results can provide some scientific basis for reservoir engineering, performance forecasting and productivity analysis of horizontal well. |
