摘要:Abstract: Influenced by the starting pressure gradient in low permeability reservoirs, there existed many problems in well test data obtained with conventional productivity equation interpreting system. By taking M Gas Field for example, starting from percolation theory, a productivity equation for fractured vertical wells considering the starting pressure gradient was established. By comparing the difference between the equation and the productivity equation of vertical well in conventional gas reservoir fracturing, a modified equation is obtained for it by modifying the binomial expression productivity equation, the correct equation was used for interpreting the tested data. The results from the modified binomial expression productivity equation and the binomial expression deliverability equation with the exponential productivity equation are compared, and combined with actual production performance, rationality of calculating the open flow capacity with the method is presented. The result provides reference for the development of M Gas Field.
