| 摘 要： | 以部分水解聚丙烯酰胺、柠檬酸铝为主要材料合成了可用于油藏深部调驱的新型胶态分散体系(HACDS),利用自吸吸入法研究了HACDS注入量、岩石渗透率等因素对岩石润湿性的影响。研究表明:HACDS的注入能使岩石的润湿性向亲水方向转化;HACDS的注入量对相对润湿指数有一定的影响;在实验测定范围内,HACDS对渗透率大的岩心润湿性的影响不如渗透率小的岩心显著。分析认为:HACDS在岩心中形成吸附膜是导致岩心润湿性改变的主要原因。

| Abstract: | A new colloidal dispersion system(HPAM /an aluminium citrate colloidal dispersion system,HACDS) made up of HPAM and aluminium citrate was prepared.The effect of HACDS,including the injected volume of HACDS and the permeability of cores,on rock wettability was studied by imbibition method.Experiments show that the injection of HACDS can change the wettability of cores.The wettability change is related to the injected volume of HACDS into the cores.With the increase of core permeability,the relative wettabili... |
