洗井保护器在机采井上的应用效果

机采井的清蜡方式主要是采用热洗方式，洗井时洗井水侵入油层，对油层造成较大伤害。在机采井上采用洗井保护器可以避免洗井水侵入油层。简述了洗井保护器的结构原理和技术特点。在胜利油田的使用情况表明，洗井保护器在流动压力较低的机采井及结蜡井上使用，具有良好的应用前景。

Effection and Application of Reservoir Protection Device on Rod Pumped Well

In the course of oil production on rod pumped well, such measures as periodic hotflushing of wells or wax-removal was necessary for ensuring normal production of the well. But this might cause severe damage to the formation. It could be prevented when a reservoir protec tion device was used. The practical operation illustrated the technique characteristic of the reservoir protection device and its affection in the field could be used on the low flow pressure reservoir and the wax well and the remarkable financial profit could be achieved.
