Multilayer commingled production is a common means for the development of multilayer tight gas reservoirs. The understanding of the production from each formation plays a significant role in the fine description of reservoir and remaining gas distribution, especially for the water-producing gas wells.
In this paper, a dynamic method for production splitting of water-producing gas wells is introduced. First, a dynamic permeability calculation method is established based on the relative permeability curve and the water-gas ratio. Then, based on the catastrophe theory, a dynamic production splitting method considering the influence of various factors (reservoir characteristics, development characteristics and geological characteristics) is established. Finally, a dynamic production splitting system is developed of multi-layer combined production gas wells.
The verification of production test data shows that the dynamic splitting method can better fit the production test results and accord with the actual production situation. This novel method can be used to split the production for the multilayer combined production well.
