尾管悬挂器喇叭口清洗技术及应用

Liner Hanger Bell Mouth Cleaning Technology and Its Application

针对尾管固井碰压后悬挂器喇叭口残余水泥致使电测遇阻等问题，研制出了悬挂器剌叭口清洗装置。该装置与稀释分散水泥浆的ＦＮ清洗液配合使用，能避免尾管固井碰压后下钻通井清洗喇叭口作业，从而保证电测和采油等后续作业的顺利进行。辽河油田现场应用表明，该装置操作简便，性能可靠。

In view that liner hanger bell mouth remains cement during drilling liner cementing bump pressure and causes hinderance in electric logging,the hanger bell mouth cleaning equipment is developed.Cooperating with FN cleaning fluid,which dilutes dispersed cement slurry,this equipment can avoid trip in drifting cleaning bell mouth operation after liner setting,therefore ensures the smooth operation of electric logging and oil production.Field application to Liaohe Oilfield verified that this kind of equipment enjoys simple operation,reliable quality and remarkable efficient.
