在油层改造中,需要往油层注入不同性质的工作液。然而在注入各种工作液后,对油层究竟产生了什么样的后果?对不同油层注入哪一种工作液效果最好?这是采油机理研究所关注的问题。这种化学剂对油层岩石结构产生的作用,很难用简单的化学反应加以认识。人们希望能够直接观察到油层岩石注入前后的结构,以及在注入不同种工作液 In the reservoir reform, the need to inject different types of working fluid into the reservoir. However, after injecting various working fluids, what kind of consequences are there to the reservoir? What is the best way to inject different working fluids into different reservoirs? This is a concern for the mechanism of oil recovery. The effect of this chemical on the rock structure of the reservoir is difficult to recognize with simple chemical reactions. People want to be able to directly observe the structure of the rock before and after injection of oil, as well as the injection of different working fluid
