摘　　要：根据沈67块的油藏特点和水井吸水剖面情况,应用弱凝胶深部调驱技术来控制油井含水上升速度,提高二次开发试验区油层动用程度。在特定参数条件下将弱凝胶调驱剂注入目的层中,在油层条件下发生反应形成堵塞物,在纵向上改善吸水剖面;在平面上改变注入水的渗流方向,扩大波及体积,提高水驱效率。通过现场应用效果分析,调驱对应油井含水稳定,油井液面降低,增油效果明显。According to the characteristics of oil reservoirs and the injection profile of water injection wells in Shen 67 block,the research and application of weak gel deep profile control technology that is used to control the raise rate of water cut in oil wellsand improve the producing degree of oil layer in secondary development test areas is discussed in this paper.
