The optimization of perforation parameters and productivity evaluation of horizontal well are one of important content of technological design in casing completion of horizontal well. Without considering the effects of wellbore pressure drawdown and completion parameters,the individual-well productivity,which is evaluated by horizontal well productivity evaluation model,is higher than the actual.Meanwhile,the model can not be used to evaluate the inflow section either. In this paper,the horizontal well productivity evaluation model of reservoir percolation and wellbore flow coupling resolution was built for the sandstone reservoir horizontal well of perforation completion by using semi-analytic method,which can provide scientific theory basis for perforation parameters of optimization design. On these bases,optimization technology of systematic perforation parameters of horization well was presented. The technology can improve individual-well recovery by homogenizing the inflow section in the horizontal interval and delaying the bottom water coning.The application result of perforation parameters optimization shows very good effect.
