Based on the multi-branch horizontal well production formula, combined with the physical basis of a low permeability reservoir, the geological models can be built. Through the simulation analysis method, we can obtain the optimal number of branches of multi-branch horizontal well, the best initial wellbore pressure, the best wellbore length, the penetration of the vertical heterogeneity how to affect the productivity of horizontal wells and the best location wellbore in the reservoir.
