摘要: 针对塔河高温高盐油藏强非均质性储层提高采收率的需求，开展了高温高盐油藏冻胶泡沫调驱技术研究。采用Ross-Miles 法和GSC 强度代码法，优选了耐温抗盐起泡剂和冻胶稳泡体系，进而确定了强度可调的冻胶泡沫调驱体系，配方为0.4%~0.5%HTSP 聚合物+0.09%~0.16%RELMNE 交联剂+0.2%~0.3%HTS-1 起泡剂，泡沫综合值是普通泡沫的2 倍以上。通过物理模拟实验评价了冻胶泡沫体系的地层适应性和提高采收率性能。实验结果表明，冻胶泡沫对地层有较好的选择适应性，在0.6~3.3 μm2 范围内，随着渗透率的增加，残余阻力系数增大，剖面改善效果明显。相比于普通泡沫、单纯气驱和水驱，冻胶泡沫技术能有效启动低渗油层，提高采收率幅度达到26.93%，是普通泡沫的2.3 倍，是注气调驱的6.2 倍，且比普通水驱最终采收率提高14.17%，具有广阔的应用前景，为塔河高温高盐油藏进一步提高采收提供了新方法。

Abstract: In view of enhanced oil recovery of high temperature, high salinity and significantly heterogeneous reservoir in Tahe Oilfield, research on technology of profile control and oil displacement with gelled foam for high temperature and high salinity reservoir was carried out in this paper. Through Ross-Miles and GSC strength code method, the heat-resistance and salt-tolerance foaming agent and gelled foam stabilizing system was optimized, and the composition and formula of gelled foam profile control and oil displacement system with adjustable strength is determined: 0.4%-0.5% HTSP polymer+0.09%-0.16% RELMNE crosslinker+0.2%-0.3% HTS-1 foaming agent. The synthetic value of foam is over two times that of common foam. The adaptability of gelled foam system to different strata and its capacity to enhance oil recovery are evaluated through physical simulation experiment. The results show that gelled foam has great selective adaptability to stratum, for permeability ranging from 0.6μm2 to 3μm2, the residual resistance factor increases with increase of formation permeability, leading to obvious profile control effect. Compared with common foam, simple gas flooding and water flooding, the gelled foam system could activate low permeability reservoir effectively and enhance oil recovery up to 26.93%. Incremental oil recovery obtained through gelled foam is 2.3 times that of common foam, 6.2 times that of gas flooding and 14.7% higher than that of common water flooding. Gelled foam has a wide application prospect, which provides a new method for further enhanced oil recovery in Tahe high temperature and high salinity reservoirs.
