Abstract: Aiming at the distribution along path problem of horizontal well injection parameters before and after gel injection profile control,an analytical method for predicting the distribution along path of injection pressure and water injection amount is established through applying the superposition principle and mirror reflection principle,and considering the influence of shaft friction.The effect of gel on the injection parameters is analyzed.This method is used to predict the distribution rule of water injection volume and injection pressure before and after gel injection profile control under homogeneous and heterogeneous conditions,which provides a guarantee for optimizing the profile control process parameters of horizontal wells and improving the effect of measures.
