三元复合驱技术发展几十年以来,开发对象已经由一类油层向二三类油层转变。二类油层由于其地质特征的特殊性和复杂性,又给三元复合驱技术的应用带来挑战。当二类油层通过强碱体系三元复合驱后取得较好效果时,我们应该继续对后续水驱阶段进行综合调整,采取各种有效的油水井措施,以确保延长试验见效期,有效改善开发效果。 Development of ternary composite flooding technology for decades, the object of development has been a type of reservoir to two or three types of reservoir changes. Due to the particularity and complexity of the geological characteristics of the second type of reservoir, the application of the ASP flooding technology poses challenges. When the two types of oil reservoirs get better effect after ASP flooding of strong alkali system, we should continue to make a comprehensive adjustment to the subsequent water flooding stages and adopt various effective oil and water well measures to ensure that the trial period is extended and the development is effectively improved effect.
