摘要
含水油井的套管破损严重影响着油田的产量和运行安全,破损套管的修复成为困扰油田的一大难题。采用CJ40-400多参数组合测井仪进行工程测井,精确测定套损管的腐蚀穿孔位置及穿孔尺寸,利用研制的Y445型封隔器对套管穿孔部位进行封堵隔离,从而使套损停产油井恢复生产,提高了出油产量,取得了良好的治理效果。
Casing damage seriously affects the well production and its service safety in the oil field,and the casing damage repair is a difficult problem. The engineering logging technology of the CJ40-400 multi parameter logging is used to measure accurately the location and size of the corrosive hole for the casing damage,then the corrosive hole of casing damage is plugged and isolated using ourselves-developed Y445 type packer. Thus,the casing loss and production stoppage of the oil well are resumed,the oil output increases,and the good improvement result is achieved.
