油井自动点滴加药装置研制与应用

摘要

In order to solve the problems such as severe waste of paraffin agent,extensive labor in-tensity and low working efficiency in the traditional method that dosing from casing tubing annu-lus,the automatic spot dosing device is developed. First,we carry out a lab simulate test,then,it was used on 10 wells and the field application shows that the device runs smoothly and reliably with simple operation,low cost,especially fit for the casing damaged well and exploration well.%为解决传统油套环空投加化学药剂浪费严重、劳动强度大、工作效率低等问题,研制了井下自动加药装置,进行了室内模拟试验,并在现场应用试验15口并.现场试验结果表明:该装置运行正常可靠,具有操作简单、成本低等特点,特别适用于套损井、边远探井.
