摘要
介绍了油井、油管线结垢产生的原因与防垢机理 ,并针对河南油田江河区油井、油管线结垢的现状 ,进行了 10余种防垢剂配方的筛选试验 ,确定了价廉高效的防垢剂、防垢液配方 ,通过岩心的吸附与解吸附试验、防垢剂各组分与地层水的配伍性试验、地层水配制溶液在 90℃下的钢片腐蚀试验等 ,确定了现场施工工艺。经现场试验 ,取得了防垢增油。
It is in detail introduced to the cause of forming scale in the oil-well and pipeline and the principle of preventing scale. According to the scale of the pipeline in Jianghe of Henan oilfield, the cheaper and more effective scale remover has been confirmed by the way of the scientific research and experiment in 3 years. The operation skills were also confirmed and the injection sequence of the diposal liquid was made out. Good affects, such as increasing oil, preventing scale and postponing the period of checking the pump, have been acquired. These experiments can provide direction of the preventing scale to Henan oilfield and the others.
