摘要
煤层气井用泡沫的稳定性决定了煤层气开发效果,引入基于离子液体(ILs)的添加剂,以提高表面活性剂泡沫的稳定性.在常温下进行大量泡沫实验,对ILs的影响进行了考察.在不同混合比下,评估了表面活性剂(MX)在有无ILs的情况下的泡沫性质.结果显示,咪唑基和共熔基的ILs能够在高温下以不同程度改善表面活性剂泡沫的稳定性,对泡沫稳定的影响在表面活性剂/IL混合比为60∶40 时更为显著.最佳配方的最高泡沫稳定性增量为不含IL配方的 136%.结果表明,离子液体在提高煤层气开发过程中表面活性剂泡沫流动性、稳定性方面具有很大的潜力.
Abstract
The stability of coalbed methane(CBM)well foams determines the effect of CBM development.In this study,ionic liquids(ILs)-based additives were introduced to improve the stability of surfactant foams.The effect of ILs was examined in a large number of foam experiments at room temperature.The foam properties of the surfactants(MX)were evaluated in the presence and absence of ILs at different mixing ratios.The results showed that imidazole-and eutectic-based ILs were able to improve surfactant foam stability at elevated temperatures to varying degrees,with the effect on foam stability being more pronounced at a surfactant/IL mixing ratio of 60∶40.The highest foam stability increment for the best formulation amounted to 136%of the IL-free formulation.The results indicated that ionic liquids had a great potential to improve the stability of surfactant foam ability during coalbed methane development.
