  This invention relates to an oil drilling foaming agent comprising a mixture of from about 40% to about 60% by weight of a branched chain hexyl poly(oxyalkanediyl) sulfuric acid or sulfuric salt combined with from about 60% to about 40% by weight of a branched chain octyl- and/or branched chain decyl- poly(oxyalkanediyl) sulfuric acid or sulfuric salt, wherein the number average molecular weight of each of the components in the mixture is between about 180 and about 600. The above composition, in the presence of moisture, provides a superiorfoaming agent which is particularly useful in geothermal and air drilling operations. The high stability and foaming power of this composition over a wide range of electrolyte and/or electrolyte-diesel fuel concentrations also recommends its use in foam marker formulations, as a component in wall board manufacture and in other energy related applications. Accordingly, the surfactant mixtures ofthe present invention are those having the basic structure: wherein n in each instance has an average value of 1 to 5, preferably 2 or3; M+ is a cation of the group H+'; Na+, K+, NH4+or an amino radical containing a lower alkyl group, preferably methyl or ethyl, R is H or methyl, and each of the C4H13-, C6H12-and C10H21-alkyl groups have a predominantly branched structure.

  本发明涉及一种石油钻井发泡剂，它由按重量计约 40%至约 60%的支链己基聚(氧烷 二基)硫酸或硫酸盐与按重量计约 60%至约 40%的支链辛基和/或支链癸基聚(氧烷 二基)硫酸或硫酸盐的混合物组成，其中混合物中各组分的平均分子量在约 180 至约 600 之间。上述组合物在有水分存在的情况下，可提供一种优异的发泡剂，特别适用于地热和空气钻探作业。这种组合物在电解质和/或电解质-柴油浓度的大范围内具有高稳定性和发泡力，因此也建议将其用于泡沫标记配方，作为墙板制造和其他与能源有关的应用中的一种成分。 因此，本发明的表面活性剂混合物是具有以下基本结构的混合物： 其中 n 在每个实例中的平均值为 1 至 5，最好是 2 或 3；M+ 是 H+'、Na+、K+、NH4+ 或含有低级烷基（最好是甲基或乙基）的氨基的阳离子；R 是 H 或甲基；C4H13-、C6H12 和 C10H21-烷基中的每个基团都具有主要的支链结构。
