摘要 KAR 299井为一口报废产水井,该井无采油树、油管头,套管头损坏严重,敞井口空井筒溢流十多年,且含气量较大。在该井的注灰永久封固施工作业中,通过采取一系列合理的工艺技术措施,成功实现了无井口装置下的注灰施工,对同类井施工具有一定的指导意义。 KAR299 is a abandoned water producing well,there is no charismas tree,tubing head,and casing head was destroyed seriously,meanwhile it has already overflowed water more than ten years with empty hole and opening wellhead,even worse the contain of gas is a little high.During permanent sealing cementing operation of this well,through taking a series of reasonable technical measures, had cemented the well successfully.All of the related technologies and methods can be used for reference of the similar operation.
