Based on the fluid theory and analysis of the advantages and disadvantages of existing models, this paper studies the characteristics of fractured horizontal wells and the distribution of fracture production in formation. According to the principle of Dupuit formula of finite conductivity vertical wells, it calculates the effective wellbore radius of production formula for horizontal wells. With the effective wellbore radius, it sets up a productivity formula group for a horizontal well with N fractures. With three fractures as examples, it analyzes the production dynamic characteristics, and gets the relationship among some parameters, including formation parameters, horizontal well fractures geometry parameters and physical parameters. This paper also studies the the impact of fractures number, spacing and other factors on flow distribution for the horizontal well fracture. It shows that this method can guide the low permeability fractured horizontal well optimization.
