塔河油田原油降凝降粘工艺技术研究与应用

Research on the chemical of Reducing Coagulability and Paraffin Preventive in Tahe Oilfield and Its Application

塔河油田开采过程中 ,由于原油粘度大、凝固点高、含蜡等特点 ,影响油井正常生产。化学清防蜡降凝降粘是原油开采稳产及远距离输送必须解决的一项重要技术 ,化学清防蜡降粘剂得到了广泛重视和应用 ,化学清防蜡降粘剂具有投资少、节省人力、物力等特点 ,而且施工工艺简单 ,因此是一种潜力极大 ,发展前景广阔的处理原油结蜡和降粘的方法。新研制DC油溶性高分子化学清防蜡降粘剂 ,能适合塔河油田四、六区的需要 ,改善原油流动状态 ,减缓油井结蜡趋势 ,降低生产成本 。

In the course of TAHE oilfield development,The production and the transportation are affected heavily by coagulability and paraffin,Then it is important to redu ce coagulability and prevent paraffin?The chemical paraffi n preventive and method of removal,as as well the chemical of reducing coagulab ility are discussed in the paper.Furthermore, a newly developed chemical method is introduced in the paper,which is easy and cheap to use in TAHE oil field,it is worth applying widely?
