摘　　要：介绍了ＳＣＨ－１ 酸化互溶剂的组成、主要性能及现场应用情况。与国内外其它酸化互溶剂相比，ＳＣＨ－１ 在保持地层的水润湿性、消除油酸乳状液、减少酸液中缓蚀剂对地层的吸附及防止酸渣形成堵塞等方面，功能更优，而价格仅为国外产品的１／２。截止１９９９ 年上半年，该互溶剂已在现场应用３００ 多井次，施工成功率１００％ ，有效率９３．３％ ，累计增油５×１０４ｔ以上，增注５１３０００ｍ ３，取得了良好的经济效益和社会效益。The paper presents the composition, main properties and field application of SCH 1 acidizing mutual solvent(AMS). Comparing with the other AMS, SCH 1 has better properties in maintaining formations water wettability, removing oil acid emulsion, reducing the adsorption of acid additive on formation and protecting acid residue forming, etc., and the price of SCH 1 is only 1/2 of foreign AMS. Up to June 1999, SCH 1 has been applied to field more than 300 wells, the application success ratio 100%, effective ratio 93.3%, cumulative incremental oil more than 5×10 4t , water injection increasing 513000 m 3, good economic benefit and social benefit have been obtained.
