摘　　要：流场调整技术就是利用注水井的不同注水量和注水方向、采油井的差异化采油强度,把地层中的剩余油驱向目的地的一种油田开发技术,比较适用于老区的再开发。基于江汉油区水驱效率降低,平面、纵向水驱不均衡现象,借助对剩余油分布的再认识,开展流场调整技术研究,建立了井网调整转流线、协调注采引流线、综合治理均衡流场、多级细分调剖面、注采偶合调流线五种转流场模式,在老区开展应用后效果较好,为江汉油区低成本控递减开辟了新途径。Flow field adjustment technology is an oilfield development technology which drives remaining oil in the stratum to the destination by means of different water injection rate and waterflood direction of water injection wells and different oil production intensity of producing wells.On the basis of reducing waterflood efficiency and unbalanced waterflooding horizontally and vertically in Jianghan Oilfield and with the help of recognition of remaining oil distribution,this paper studies flow field adjustment technology and establishes five flow field transformation modes which have a good application result in maturing oilfield and open up a new path for low-cost control over decreasing in Jianghan Oilfield.
