改善蒸汽驱效果的高温泡沫剂研究

Study on high temperature foamer in heavy oil steam stimulation

利用自主研发的泡沫剂GFPJ,通过引入不同类型的高温泡沫稳定剂,得到能够满足稠油蒸汽驱要求的高温泡沫剂体系。对不同高温泡沫剂体系的发泡性能、耐高温性能以及高温封堵性能进行了研究。通过对不同高温泡沫剂体系老化前后有效含量的变化测定,表明了高温泡沫稳定剂的主要作用是能够降低泡沫剂的降解速率,从而提高泡沫剂体系的耐高温性能。

High temperature foamer systems were obtained by introducing different kinds of high temperature foam stabilizers using foamer GFPJ with self-research and development,which could meet the requirements of heavy oil steam stimulation.Foam performance,high temperature resistant properties and high temperature plugging performance of different foamer were studied.Changes of effective contents of different foamer during aging showed that the principal role of high temperature foam stabilizers was to reduce the degradation rate of foamer and improve high temperature resistant properties.
