Imitation horizontal well waterflooding well pattern adapting method

The invention provides an imitation horizontal well waterflooding well pattern adapting method which comprises the steps that the optimal well pattern form is obtained through a numerical reservoir simulation method, and models with different included angles between fissures and a well array are established for simulation and prediction; the array spacing of the optimal well pattern form under different permeability conditions is optimized, and the optimal well array spacing is obtained under different permeability range conditions; the reasonable well pattern density is determined, the economical and reasonable well spacing is calculated, the well spacing is determined accordingly, and the fissures are made to adapt to the well spacing; numerical simulation is conducted, and the optimal fissure construction parameters matched with different matrix permeability, and the optimal injection-production parameters are obtained; and the technology for adaption of the well pattern, the fissures and water injection d
