| A METHOD OF AND INSTALLATION FOR PREVENTION AND ELIMINATION OF PARAFFIN SLUGS IN OIL AND GAS WELLS |
| In the first modification of the method, cable is adjusted to downhole conditions. For this purpose, the cable is placed in a well at a maximally possible length and remains there for 1 hour to 5 days. This time is good enough for the cable natural extension. Then, the cable is heated up to an optimal working temperature and held out in a heated state over 1 to 3 hours. After that, the cable is withdrawn from the well; cable core is closed with a heating element, taking into account different natural elongation of its parts happened due to gravity force and heating effects. The difference in elongation is connected with different linear expansion rates of the cable copper core and cable steel armor. |
