摘要
将液体茶皂素与９４１Ａ试剂以８∶２的质量比混合，制成了发泡剂ＴＳＦ。用Ｗａｒｉｎｇ混调器法和ＡＰＩ推荐法在不同条件下对ＴＳＦ的发泡性能进行了评价，结果表明ＴＳＦ适应能力强，尤其适用于油、盐卤共存的混合体系，与ＫＣｌ和井壁稳定剂ＦＡ３６７配伍性好，是空气钻井用的一种优良发泡剂。
oaming agent TSF is composed of commercial liquid tea saponin and organic reagent 491A in mass ratio 8∶2. In this work the foaming properties of TSF are investigated mostly by a simple and fast method with Waring Blender. It is shown that TSF forms voluminous stable foams of long halflife in fresh and salts waters (brines), of high Ca/Mg contents, with and without kerosine added, in aqueous KCl+Na2CO3 solution with and without kerosine added. The foaming properties of TSF solutions change slightly at pH 6-13, maximal values reached at pH=7. TSF is compatible well with polymer holestabilizer FA367. The results of evaluating TSF by using Waring Blender and by API recommended method are in good agreement and shown to be the best in comparison with other foamers.
