摘　　要：井楼油田七区核Ⅳ2-3小层属普通稠油油藏,经过多年开发后,油井普遍进入中高周期生产,压力保持水平低,递减加大,汽窜频繁,开发效果变差,吞吐中后期配套化学辅助蒸汽吞吐,但是如何经济应用此项技术尚未深入研究。结合河南油田技术应用现状,通过建立三维地质模型,利用数据模拟进行化学辅助蒸汽吞吐注入浓度优化设计研究,为经济有效提高浅薄层普通稠油油藏采收率提供依据。The 2-3 members of Eh4 in Region 7 of Jinlou Oilfield belonged to general heavy oil reservoirs,after many years of production,wells were produced at mid-high stages and pressure was low in the wells with high production depletion and steam channeling,production effect was poor and chemical-added steam soak was used at the mid-late stages of steam soak,and deep study of the economic use of the technique was not carried out.In combination with the technical application in Henan Oilfield,a 3D geologic model is established and numerical simulation is used for optimizing the design of chemical-added steam drive,it provides a basis for enhancing oil recovery of heavy oil reservoirs.
