摘　　要：针对高凝油油田注水井在注水过程中地层温度降低产生的“冷伤害”问题 ,研制了井下电加热技术 ,并进行了室内实验和现场试验。结果表明 ,利用该技术可提高地层温度 ,提高注水井的注水效果 ,降低注水压力 ,提高区块的开发速度 ;该技术具有广阔的应用前景。Starting from 'cold damage' arising from low formation temperature in water injection of high pour point oilfield, downhole electric heating technology emerges and has gone through indoors and site pilot tests. Results shows application of this technology will ensure higher formation temperature, improved water injection effect, lower water injection pressure and faster development speed. In particular, it is the first of this kind in China with promising prospect.
