复杂区块井筒结盐综合治理技术

Comprehensive treatment of salt deposition in well bores in special block

针对濮城油田部分低渗透、高矿化度复杂断块油藏生产油井结盐严重的特点 ,通过对油井盐样室内试验 ,剖析了结盐的原因及影响因素 ,提出了相应的井筒清、防盐配套新技术 ,在现场应用取得了良好效果。

In accordance with the serious problem of salt deposition in production wells of low permeability,high salinity,complex fauIted block reservoirs in Pucheng oilfield,through laboratory experiment,the reason of salt deposition and its influence have been analyzed. Necessary measures of salt removal and control have been proposed and proved to be effective after field application.
