摘要
认识水驱前缘分布是注水开发油藏开展各项调整工作的基础。目前，国内外研究水驱前缘的方法主要有油藏工程、物理模拟、动态监测和数值模拟等，这些方法在长庆低渗透油藏应用中存在诸多局限。以安塞油田W16—15井区为例，探讨了通过注“虚拟示踪剂”，结合动态监测资料，应用环境示踪模拟追踪“虚拟示踪剂”流动，实现了水驱前缘准确描述和预测．并提出了研究区进一步提高采收率方向。
Understanding of the waterflooding front distribution is the basis for watertlooding reservoirs to carry out various adjustment works. Currently, the methods of waterflooding front research at home and abroad are mainly reservoir engineering, physical sinmla- tion, dynamic monitoring and numerical simulation. There are many limitations of these methods in the applieation to low permeability reservoirs in Changqing Oilfield. Taking the W16-15 area of Ansai Oilfield as an example, to track the flow of ＂virtual tracer ＂by simulation with application of environmental tracer is discussed through injecting the ＂virtual tracer＂ and combining performance monitoring data. Accurate description and prediction of waterflood front are achieved. The direction of further EOR in the study area is proposed
