摘要:
针对某高矿化度油藏采用常规化学剂不抗盐,提高采收率难度大的问题,在高矿化度油藏条件下,以泡沫综合指数(FCI)筛选了两种起泡性好的表面活性剂TSS(12-2-12)-2OH和Triton X-100。在此基础上,优化了聚合物基微泡沫驱油体系中的起泡剂浓度、助起泡剂浓度和泡沫稳泡剂浓度,得到了最佳的聚合物基微泡沫驱油体系0.2%(w) TSS(12-2-12)-2OH +0.1%(w) Triton X-100+0.150%(w) KY5S+地层水。为高矿化度油藏提高采收率提供一条新的途径。

Abstract:
Aiming at the practical problems of conventional chemical agent used in a high salinity reservoir, having anti-salt property scarcely and improving the recovery rate difficultly, then FCI foam comprehensive exponent was uesd to screen two kinds of surface active agents TSS(12-2-12)-2OH and Triton X-100 under the conditions of high salinity reservoir. The foaming agent concentration, auxiliary foaming agent concentration and bubble foam stabilizing agent concentration were optimized. The result showed that the optimal polymer based on micro-foam flooding system was 0.2 wt% TSS(12-2-12)-2OH +0.1 wt% Triton X-100+0.15 wt% KY5S+ formation water. It supplies a new method to enhance oil recovery for high salinity reservoirs.
