摘要
目前,我国大部分油田已经进入开发的中后期,普遍采用的是注水开发工艺、多层位混合开采和多层位混合输送的处理工艺。若注入水和地层水之间不配伍或者不同层位采出水之间配伍性差,就会形成各种类型的油田结垢。结垢不仅造成储层堵塞,会给储层带来伤害,也会给设备和集输管道带来不同程度的腐蚀,降低设备的传热速率和堵塞管道的危害。本文主要介绍了油田采出水中垢的结垢成因、结垢危害、结垢趋势预测以及防垢技术,并以此作为配伍性实验理论研究的基础,对混采混输及回注工艺具有一定的现实指导意义。
At present , most oilfields in our country entered to the mid -late development , water flooding technology was widely accepted , multi-layer hybrid mining and multi -layer hybrid conveying process.If no compatibility between injected water and formation water or compatibility between different horizon produced water was poor , it can form various types of oil field scale.Scale reservoir caused by congestion , not only can bring damage to reservoir , also can give bring different degree of corrosion of equipment and pipeline , reduce the heat transfer rate of equipment and pipeline.The scale formation , fouling hazards , scaling trend prediction and antiscale technology in oilfield produced water were introduced.As the basis of the theory of compatibility experiments , it had a certain realistic guiding significance in mixed mining , mixed transportation and reinjection process.
