摘　　要：河南油田江河区经多年注水开采,注水井分注朝着多级方向发展。多级分注合格率低,管理难度大,无效注水量难以有效控制。为此,利用无机纳米活性功能材料的特点,运用室内实验方法进行优选评价,研制开发了适用于高压注水井简化管柱的纳米堵剂。现场应用表明,纳米堵剂是解决高温高压低渗透油藏疑难注水井简化管柱的一种新方法。After many years of water flooding in Jianghe area of Henan Oilfield,separate water injection shows a trend of multi-stage development.Multi-stage separate injection has low acceptance rate,and it is difficult to control invalid injection.Hence,a nanometer blocking agent has been developed for the simplified string of high pressure injectors by making the advantage of inorganic nanometer active functional material and using laboratory experiment method to perform optimization and evaluation.Field application shows that nanometer blocking agent is a new method for the simplified string of knotty injectors in high-temperature high-pressure and low permeability reservoirs.
