Analysis and Application of Several Methods of Inflow Performance Relationship

In order to comprehend producet characteristic of oil reservoir,and evaluaterate its production capacity,we must master the characteristic of Inflow Performance Relationship(IPR) under different production mode of oil well.IPR is the integrated reflection of operating characteristic hydrocarbon zone,so it is not only the main reference for determining the reasonable operating practice,but also is the base for analyzing the performance and production capacity of oil/gas well.Since Vogel proposed the IPR method,Standing,Fetkoich,Klins,Clark and МУСДИМОВ.Р.Х etc improve and innovate IPR equations,and make the IPR methods can be fit for the reservoir of multiphase flow and multi-element influence.This paper analyse the several common IPR method,and study the relationships and variation pattern of bottom hole flowing pressure,well yield average reservoir pressure and water content ratio,and also analyse practical application.
