    • A method for cleaning oil wells to increase the flow of oil thereof by use of a unique aqueous cleaning emulsion comprising of water, hydrocarbon solvent, detergent and acid. This one step method provides for the simultaneously cleaning/removal of asphaltene and/or paraffin and scale. This method can be used alone or with the assistance of a wash tool which is a combination pressure and surge wash tool having a nipple assembly. A by-pass port is coupled to the nipple assembly and a diverter cup is coupled to the by-pass port. A plurality of pressure wash cups are positioned on the tool. A pressure wash port is located between the plurality of pressure wash cups and a pump shoe assembly is coupled to a bottom pressure wash cup.
    • 一种清洁油井以通过使用由水,烃溶剂,洗涤剂和酸组成的独特的水性清洁乳液来增加其油流量的方法。 该一步法同时清洁/除去沥青质和/或石蜡和氧化皮。 该方法可以单独使用或者在具有乳头组件的组合压力和浪涌洗涤工具的洗涤工具的帮助下使用。 旁通端口联接到乳头组件,分流杯联接到旁路端口。 多个压力洗涤杯位于工具上。 压力清洗口位于多个压力洗涤杯之间,并且泵靴组件联接到底部压力洗涤杯。
