摘      要：To improve the productivity of oil wells,perforation technology is usually used to improve the productivity of horizontal wells in oilfield *** the perforation operation,the perforation channel around the wellbore will form a near-well high-permeability reservoir area with the penetration depth as the radius,that is,the formation has different permeability characteristics with the perforation depth as the dividing ***,the permeability is measured by the permeability tester,but this approach has a high workload and limited *** this paper,according to the reservoir characteristics of perforated horizontal wells,the reservoir is divided into two areas:the original reservoir area and the near-well high permeability reservoir *** on the theory of seepage mechanics and the formula of open hole productivity,the permeability calculation formula of near-well high permeability reservoir area with perforation parameters is *** to the principle of seepage continuity,the seepage is regarded as the synthesis of two directions:the horizontal plane elliptic seepage field and the vertical plane radial seepage field,and the oil well productivity prediction model of the perforated horizontal well is established by *** model comparison demonstrates that the model is reasonable and *** calculate and analyze the effect of oil well production and the law of influencing factors,actual production data of the oilfield are substituted into the oil well productivity *** can effectively guide the technical process design and effect prediction of perforated horizontal wells.
