摘　　要：吴起油田A油区延10油藏2018年开始注水开发,主力层位为延10^(1-1),采用边缘+点状注采井网,注水开发后油区自然递减率下降明显,但延10油藏平面非均质性强,造成注水后水线推进不均匀,部分油井含水率上升速度较快,因此需要对油田注水开发效果进行评价,为综合治理提供依据。The Yan10 oil reservoir in A oil region of Wuqi oilfield started water injection development in 2018,and the main layer was Yan10^(1-1).The edge+point shaped water injection well network was adopted,and the natural decline rate of the oil region decreased obviously after water injection development.However,the heterogeneity of the Yan10 oil reservoir plane was highly,causing uneven water line advancement after water injection,and some oil wells had a fast increase in water content.Therefore,it is necessary to evaluate the effectiveness of oilfield water injection development for providing a basis for comprehensive management.
