    • A method of treating a hydrocarbon containing formation, comprising (a) providing a hydrocarbon recovery composition to at least a portion of the hydrocarbon containing formation, wherein the hydrocarbon recovery composition comprises a propoxylated composition which comprises (1) a glycerol sulfonate of a propoxylated primary alcohol having a branched aliphatic group with an average carbon number from 10 to 24 and having an average number of branches per aliphatic group of from 0.7 to 2.5 and having at least 0.5, preferably from 3 to 12, moles of propylene oxide per mole of primary alcohol and (2) polypropylene glycol; provided that the primary alcohol is propoxylated by contacting the alcohol with propylene oxide in the presence of a catalytically effective amount of one or more of the phosphate salts of lanthanum series elements or the rare earth elements, preferably a carbonate salt thereof, wherein the propoxylated composition comprising the propoxylated alcohol and from 1 to 30 wt% of polypropylene glycol is produced; and (b) allowing the composition to interact with hydrocarbons in the hydrocarbon containing formation.
    • 一种处理含烃地层的方法,包括(a)向所述含烃地层的至少一部分提供烃回收组合物,其中所述烃回收组合物包含丙氧基化组合物,其包含(1)丙氧基化初级的甘油磺酸盐 具有平均碳数为10至24并且每个脂族基团的平均分支数为0.7至2.5并且每摩尔初级粒子具有至少0.5,优选3至12摩尔环氧丙烷的支链脂族基团的醇的醇, 醇和(2)聚丙二醇; 条件是通过在催化有效量的一种或多种镧系元素的磷酸盐或稀土元素,优选其碳酸盐的存在下使醇与环氧丙烷接触,将伯醇丙氧基化,其中丙氧基化组合物 包括丙氧基化醇和1至30wt%的聚丙二醇; 和(b)允许组合物与含烃地层中的烃相互作用。
