摘要
试验模拟二元复合驱油体系及地层中原油形成乳状液条件,通过对室内模拟形成的乳状液。通过单一变量法改变形成乳状液所需的二元复合体系及原油的浓度,分别研究各变量对乳状液的稳定性及乳状液类型的影响规律。研究结果表明:对形成乳状液类型影响最大的是油水比。对于乳状液稳定性,O/W型乳状液中聚合物对乳状液体系稳定起到积极作用,活性剂浓度高于50 mg/L时起到消极作用;W/O型乳状液中聚合物不利于乳状液稳定性,活性剂随着浓度的增加对乳状液稳定性由消极作用转变为积极作用。
The configuration conditions of emulsion were studied. By using the single variable method to change the two-element complex system and the concentration of crude oil, effect of the variables on the stability of the emulsion and the type of emulsion were investigated. The results show that： the greatest impact on the formation of emulsion type is the oil / water ratio. For emulsion stability, the polymer in O/W emulsion has a positive effect on the stability of the emulsion system, and the concentration of the active agent is higher than 50 mg/L, the polymer is not conducive to the stability of W/O emulsion.
