摘要
Abstract
Recovery rate is one of the key development index which can affect the ultimate development effect of oilfields whether it remains high or low,therefore,the researches of reasonable recovery rate and influence factors play an important role in production decision of oilfields. Previous authors researched the recovery rate mainly based on reservoir numerical simulation and mathematical statistics,however,the certain limitation is both theoretic and applied aspects. Based on the flow fraction equation,we create the relation expression among recovery rate and reservoir properties,water cut and annual ascending velocity of water cut,and analyze the influence of individual factor on recovery rate. The theoretical analysis result shows that coefficient b by regression between ratio of oil to water relative permeability and water saturation is negative correlation to recovery rate. Water cut is negatively correlated to recovery rate when fw<50%,and positively correlated when fw>50%. At different stages of water cut,the faster the velocity of water cut ascends,the higher recovery rate could be. The method discussed in this paper could be applied to the evaluation of theoretical recovery rate of certain reservoir at different development stages.关键词
