中文摘要:
      苯乙烯焦油的产量多、价廉,但利用率不高,多用于燃烧,对环境有一定的污染。因此,为了提升苯乙烯焦油的经济附加值,同时给油田开发提供一种低成本的原材料,将苯乙烯焦油制成水包油型乳状液,用于乳状液驱油中。实验以乳化不稳定系数为乳化剂的筛选指标,并对筛选出来的乳状液进行稳定性、流变性及驱油性评价,为苯乙烯焦油乳状液驱油在高含水后期的现场应用提供理论和实验依据。结果表明:苯乙烯焦油制备的水包油型乳状液的驱油效果较好,具有很好的提高采收率应用潜力。当乳化剂含量为0.3%、MOE-20与AES复配质量比为1:1时,乳状液的稳定性最好。针对黏度为185 mPa.s的普通稠油,高含水后期的岩心驱替实验表明,苯乙烯焦油制备的水包油乳状液可以在水驱基础上提高采收率增值达到16%以上。
英文摘要:
      The production of styrene tar is high and the price is cheap. However, utilization ratio of styrene tar is not high and the burning of styrene tar have pollution to environment. Therefore, in order to enhance the economic value added of styrene tar and provide a kind of low-cost raw material for oilfield development, styrene tar is made into O/W emulsion used in oil displacement process. In the screening experiment of emulsifier, the emulsification instability coefficient was used as a screening index, and the stability, rheology behavior and capability of oil displacement of the screened emulsion were evaluated, which provided theoretical and experimental basis for the field application of styrene-tar type emulsion oil displacement in the later stage of high water cut. The result indicates that oil-in-water emulsion prepared from styrene tar has a good oil displacement effect and a good application potential of enhanced recovery. The stability of the emulsion was best when the emulsifier content was 0.3% and the mass ratio of MOE-20 to AES was 1:1. For the conventional heavy oil with viscosity of 185 mPa.s, the core displacement experiment at the later stage of high water cut showed that oil-in-water emulsion prepared by styrene tar can increase the recovery ratio by more than 16% on the basis of water flooding.
