摘　　要：合理注采比是使目前压力系统在规定时间内达到合理地层压力,以满足油田充沛产能,保证经济效益的重要依据.基于注采关系分析法,建立合理地层压力数学计算模型,将其作为压力恢复目标,选择不同的压力恢复速度,遵循物质平衡原理,建立注采比与压力恢复速度关系,进行合理注采比研究.针对M油田计算得出,层系1合理地层压力为11.39MPa,应以0.9307的注采比进行开发;层系2的合理地层压力为11.84MPa,应以1.1101的注采比进行注水开发;层系3的合理地层压力为13.91MPa,应以0.8522的注采比进行注水开发,结果表明该研究对于合理地层压力恢复具有一定的指导意义和实用价值.A reasonable injection production ratio is an important basis for achieving rea-sonable formation pressure in the current pressure system within a specified time,in order to meet the abundant production capacity of the oilfield and ensure economic benefits.Based on the injection production relationship analysis method,this article establishes a mathematical calculation model for reasonable formation pressure,which is used as the pressure recovery target.Different pressure recovery rates are selected,and the relationship between injection production ratio and pressure recovery rate is established following the principle of material balance,Conduct a reasonable injection production ratio study.Based on calculations for M oilfield,the reasonable formation pressure for layer 1 is 11.39 MPa,and the development should be carried out with an injection production ratio of 0.9307;The reasonable formation pressure for layer 2 is 11.84 MPa,and water injection development should be carried out with an injec-tion production ratio of 1.1101;The reasonable formation pressure for layer 3 is 13.91 MPa,and water injection development should be carried out with an injection production ratio of 0.8522.The results show that this study has certain guiding significance and practical value for the recovery of reasonable formation pressure.
