由于油层的非均质性，注入的聚合物液往往沿高渗透部位突进，而驱替不到低渗透部位中的原油。为此，大庆石油管理局采油工艺研究所研制出了流动凝胶调剖技术。其原理是将调剖剂与交联剂等辅助剂，在地面按配方比例配制后，注入地层，在地层条件下形成冻胶，堵塞高渗透层的... Due to the heterogeneity of the reservoir, the injected polymer fluid tends to protrude along the high-permeability sites and can not displace the crude oil in the low-permeability sites. To this end, Daqing Petroleum Administration Institute of Oil Technology has developed a mobile gel profile control technology. The principle is that the profile control agent and cross-linking agent and other auxiliaries are formulated on the ground according to the proportion of the formulation, and then injected into the formation to form gel in the formation ...
