Application of Ⅰ-Frequency Skin Effect Electric Heating to High Pour Point and High Viscous Oil Production and Transportation

摘要

@@ In Dagang Oil Fields, Ⅰ-frequency skin effect electric heating techniques have been successfully applied to the transportation of high pour point and high viscous oil. From 1990 upto now, Ⅰ-frequency skin effect electric thermal rod has been used in 110 well-times in Dagang Oil Fields, and of oil has been cumulatively increased 153 600 tons. The electric thermal rod has been applied in many oilfields such as Liaohe, Shengli, Anhui, Jiangsu, Huabei, Nanyang, Inner Mongolia and even Russia. It has obtained good reputation.
