摘　　要：泡沫排水采气方法是一种经济性高、效率高、施工方便的排水采气方法,在油气田得到了广泛的应用。气井泡沫排液所使用的泡排剂直接影响到排液的效率,针对大量的泡排剂不能同时适合高温、高矿化度和高凝析油气水井的情况,结合有水气藏的开发特点,根据表面活性剂理论和起泡性、稳泡性理论,在实验的基础上采用正交设计实验方法研制了一种新型泡沫排水剂———LH。采用Ross-Miles法和搅拌法对泡排剂LH进行泡沫静态性能研究,利用现场取得的凝析油和地层水对新型泡排剂LH的起泡能力、抗矿化度能力、抗凝析油能力及其抗高温能力进行了系统的分析和研究。并在同等实验的条件下与其他泡排剂进行比较,实验结果表明,泡排剂LH是一种起泡性能好、泡沫稳定性优良、抗高温、抗高矿化度、抗高凝析油的泡排剂。Foam-dewatering gas production method, being economic, efficient, and easy to perform dewatering gas production method, has been widely used in oil field production. Foaming agent used in gas well forming-boosting has a direct impact on dewatering efficiency. To deal with the situation that the majority of forming agents fail to serve gas wells with high temperature, high salinity, and high condensate/condensate oil, a new kind of foaming agent LH has been developed via cross experimental design method based on the consideration of development characteristic of gas reservoir with water content and the surfactant theory and foam-boosting/foam-steady theory. Static performance study of foaming agent LH has been done by Ross-Miles method and stirring method. The analysis and study have also been carried out on bubbling ability, total salinity resistance, condensed oil resistance and high temperature resistance of LH with condensate oil and formation water obtained from site. The results are then compared to other forming agent under the same experimental conditions. The comparison indicates LH is a foaming agent of good bubbling ability, high temperature resistance, high total salinity resistance, and high condensate oil resistance.
