    • The present invention deals with a method to liquefy the viscous oil of oil wells and also to clean the paraffin off the walls of tubing and other production equipment. The method consists in using heat produced by a thermal generator, and also using steam produced by the contact between the thermal generator and water. The thermal generator is a metallic shielded container of cylindrical shape holding individual units of already encapsulated Strontium-90 sources able to generate a temperature of 100 degree Celsius or a combination of encapsulated Strontium-90 sources able to generate 100 degree Celsius each in order to obtain, according to necessities, up to or over 600 degree Celsius. The thermal generator is transported in a metal housing.
    • 本发明涉及一种液化油井粘性油的方法,也用于清理管道和其他生产设备的石蜡。 该方法包括使用由热发生器产生的热量,并且还使用由热发生器和水之间的接触产生的蒸汽。 热发生器是一种圆柱形的金属屏蔽容器,其具有能够产生100摄氏度的温度或可以产生100摄氏度的封装的锶-90源的已经封装的锶-90源的各个单元,以获得 ,根据需要,可达600摄氏度以上。 热发生器在金属外壳中运输。
