AbstractThe mathematical model of coupled flow and geomechanics for a vertical fractured well in tight gas reservoirs was established. The analytical modeling of unidirectional flow and radial flow was achieved by Laplace transforms and integral transforms. The results show that uncoupled flow would lead to an overestimate in performance of a vertical fractured well, especially in the later stage. The production rate decreases with elastic modulus because porosity and permeability decrease accordingly. Drawdown pressure should be optimized to lower the impact of coupled flow and geomechanics as a result of permeability decreasing. Production rate increases with fracture half-length significantly in the initial stage and becomes stable gradually. This study could provide a theoretical basis for effective development of tight gas reservoirs.

Because the extremely low permeability for tight gas reservoirs, lead to the way to seepage and the shape of production curves different with the convention reservoirs; this will increase the difficulty to develop the tight gas reservoirs; on the other hand, the convention exploit cannot recover the tight gas with commercial value, with this problem, the main solution is the technology of multi-stage fractured horizontal wells, the fractured can provide the channel for gas to transport, the horizontal wells can increase the seepage area of tight gas, it’s the guarantee to get the commercial value. But, at present, the study on the tight was dependent on the method of convention gas reservoirs, the production curve get from this method also the same with the convention gas reservoirs, in order to close with the really exploitation of tight gas reservoirs and provide the more accurate scientific evidence, we must study based on the feature of tight gas reservoir, in this situation, we can get the suitable production curves for tight gas reservoirs. This paper based on the feature of tight gas reservoir, combine with the model of multi-stage fractured horizontal wells, and get the production equation of tight gas, combine with the yield of discard time, we can get the type curve, and then get the C level reserves of region.
