摘　　要：针对低油价形势下非均相复合驱在现场应用中成本高的问题,开展非均相复合驱注入方式的优化研究。文本通过物理模拟实验方法,通过并联填砂管模拟非均质地层,对非均质油层非均相复合驱油体系的注入方式进行研究。实验结果表明,在相同成本化学剂用量下,合理的多段塞交替注入能够有效改善低渗层的吸液效果,提高低渗层的动用程度;较单一段塞注入提升采收率5%左右。Aiming at the problem of high cost in the field application of heterogeneous compound flooding under the situation of low oil price, the optimization of injection mode of heterogeneous combination flooding is carried out. In this paper, through the physical simulation experiment method, through the parallel sand filling pipe to simulate the heterogeneous layer, the heterogeneous oil reservoir injection mode is studied. The experimental results show that, under the same cost chemical dosage, the reasonable multiple -slug alternating injection can effectively improve the suction effect of the low permeability layer,improve the utilization degree of the low permeability layer,and increase the recovery rate by about 5%.
