摘要
油田开发过程中,经常出现油井结蜡问题,有些油井结蜡严重导致产量大幅下降,甚至停产。油井结蜡主要与温度、管壁剪切力、流速、蜡浓度梯度、含水率等因素有关。目前我国清防蜡采取的主要措施是热力和机械清蜡,近几年化学防蜡和微生物防蜡发展迅速。通过清除油井中的蜡,提高油井产量,增加产油效率。
In the process of oilfield development, Oil wells often appear wax problems, the paraffin wax is mainly related with the temperature, tube wall shear stress, velocity, wax concentration gradient, moisture content and other factors. At present, our main measures taken Paraffin wax is thermal and mechanical, in recent years, anti-chemical and microbiological Paraffin wax is developing rapidly. Oil production and oil production efficiency were increased by removing the wax oil.
