以子长油区7410注水井组为例,通过井间示踪剂监测技术来认识油藏的非均质特征和评价二、三次采油方法提高采收率机理,及时有效分析油藏层系间的串通关系,掌握注水导流方向和注入水的地下运动规律,为提高水驱效率,开展多项综合治理措施提供可靠的依据,从而为油田的调整挖潜,提高油田管理水平提供重要依据。
Taking the 7410 water injection well group in Zichang oil region as an example, the cross-well tracer monitoring technology is used to understand the reservoir heterogeneity and to evaluate the mechanism of enhanced oil recovery by the second and third recovery methods to analyze the reservoir interval , It is important to grasp the relationship between the diversion direction of water injection and underground movement of injected water so as to provide a reliable basis for improving the waterflooding efficiency and carrying out a number of comprehensive management measures so as to provide an important basis for the adjustment of the oilfield and the improvement of the management level of the oilfield.
