摘要
根据表面活性剂的清洗原理及油田采油管结蜡油污的特性,研制与合成了CL-6全水基油田采油管特效清洗剂。室内性能评价与油田现场应用结果表明,该清洗剂可有效清除采油管的结蜡,洗通油管,使用浓度低,可静态清洗,废油可漂浮在液面加以回收。清洗液可长期使用,接近于无排放,对油管无腐蚀作用,并有优良的缓蚀性能。
The Cleaning agent CL-6 is composed of surfactants (a nonionic, H-9, and a specially synthesized anionic, LC-1, which possesses polar functional group at orthoposition of alkyl naphthyl radical), an aromatic cardoxylic acid, HS-1 , a nontoxic corrosion inhibitor, CL-3, and auxilliaries GLT, mainly inorganic salts, It is manufactured in granules of blueish color with purity 98％ and used in aqueous solutions, The functions of each ingredient, the preparation of and mechanizms of removing gunk and wax accumulations by CL-6 are descrided. The use level of CL-1 is 3—5％, however, a 0.5％ solution is just effective. Cleaning operations are recommended at 70℃. The cleaning aqueous solutions of CL-6 can serve over a long time with replenishing the chemical to maintain the solution concentration when needed. The uses of CL-6 in several main Oil Fields are presented.
