摘　　要：针对河南油田七区Ⅳ2-3油藏具有埋藏浅、油层薄、油质稠、分布散、纯总厚度比低、储层非均质性严重的特点,通过建立油藏数值模型,结合数值模拟和油藏工程综合研究,找出了剩余油分布规律,研究了加密井吞吐潜力和加密时机;在综合考虑开发效果和经济效益的基础上,得到加密井数为3口时单井利润最大,采出程度为15%时总利润最大;研究结果可为目标区块以及同类区块的有效开发提供技术依据。In consideration of the characteristics of shallow burial,thin reservoir,viscous oil,scatter oil distribution,total and low net thickness of reservoir and serious reservoir heterogeneity in Ⅳ2-3 reservoir of Region 7 in Henan Oilfield,a reservoir simulating model was established for clarifying the remaining oil distribution rules in combination with numerical simulation and reservoir engineering,well infilled potential and time were studied.On the basis of comprehensive study of oilfield production effect and its economic profit,it is considered that rational well infilled number is 3 wells for recovery ratio of 15% with maximum profit.It provides a basis for effective development of the target and similar blocks.
