摘　　要：针对胜利渤南油田高温低渗油藏常规酸化有效期短、増注机理存在缺陷、效果不理想的现状,应用物理模拟方法,研究了网状胶束—酸复合増注体系,评价和测定了体系不同组合方式下的増注能力和抗污染能力。结果表明,体系具有增注效果好、"低注水量恢复期"短、作用机理全面、增注后岩心抗原油污染能力强等优势。Bonan Oilfield belongs to high temperature and low permeability reservoir,resulting in short effective period of conventional acid process,defect injection mechanism,so the effect is not ideal. By a physical simulation method,micellar net-acid compound injection system is studied to evaluate and determine its injection capability and the ability of anti-pollution in different patterns. Results show that the system has good injection effect,and＂low water injection recovery period＂is short. Other advantages include comprehensive action mechanism and strong core antigen oil pollution ability after the injection.
