Ash单元为非均质油藏 ,有高渗透层窜流现象。为了改善流度比和提高波及效率 ,采用了非交联聚合物、胶态分散凝胶(CDG)和整体凝胶三个阶段处理的工艺技术。共注入聚合物和凝胶溶液 0 2 6 2PV ,增油 2 35 0 0 0～385 0 0 0bbl,提高采收率 1 7 2 %OOIP ,工艺成本为 0 91～ 1 49/bbl。连续不断的现场动态监测对及时改进工艺技术和采用合适的新技术具有非常重要的意义。 Ash units are heterogeneous reservoirs with a high permeability stratified flow. In order to improve the flow ratio and improve the sweep efficiency, using non-crosslinked polymer, colloidal dispersion gel (CDG) and the whole gel three-stage processing technology. A total of 0 2 6 2PV of polymer and gel solution was injected into the reactor to increase the oil recovery by 35 35 0 0 0 38 0 0 0 bbl, and the oil recovery rate was 17 2% OOIP. The cost of the process was 0 91-1 49 / bbl. Continuous on-site dynamic monitoring on the timely improvement of process technology and the use of appropriate new technology is of great significance.
