摘　　要：石油是影响社会经济发展的主要资源之一,随着工业发展速度的不断提升,对石油开采率的要求也在不断提高,随着油田开采时间的越来越长,油层自身的能量被大量消耗,油层问题逐渐呈现,开采难度加大,部分注水井注入压力升高,在常规压力范围内无法完成配注量的要求,严重影响了油井产量,为了进一步挖掘油田潜力,通过采取适用的酸化增注措施,提高油田产出量。Petroleum is one of the main resources affecting social and economic development.With the increasing speed of industrial development,The demand for oil recovery is also increasing.With the development of oil field,the energy of reservoir itself is consumed greatly.Reservoir problems are gradually emerging,the difficulty of production is increasing,and injection pressure of some water injection wells is increasing.The requirement of injection allocation can not be fulfilled within the normal pressure range,which seriously affects the production of oil wells.In order to further tap the potential of the oilfield,the output of the oilfield is increased by taking appropriate acidizing and injection stimulation measures.
