摘　　要：注水开发油田中,结垢是油井生产中一种比较普遍的现象,对油井生产有很大的影响。室内及现场生产实践发现,油井在注水见效后的不同阶段,其结垢成分和结垢部位各不相同,具有一定的特征。以长庆油田一些区块的油井生产为例,论述了这一问题,对类似的油田清防垢工作有一定的借鉴作用。In the flood development of oilfield,fouling is universal phenomenon in oil well production,which affects oil well production strongly.In-house study and field production practice discover that fouling ingredient and fouling position are different in different moment after oil well effective response for water flood,possessing definite characteristics.This paper discusses this problem taking the case of some places in Changqing oilfield,which provides definite reference for similar clearing and preventing fouling.
