近年来文南油田随着分注井工作量的增加和油管投入资金的不足,部分分注井使用的油管为一级试压合格管,但由于缺乏油管检测手段,分注时往往因油管不合格造成封隔器管柱失效,在作业现场也无法有效检查油管是否合格,因此对下步施工带来很大的难度。多功能验封管柱能有效判定管柱失效原因,为下步换封提供了有效依据,为作业是否更换油管提供了直接依据,避免盲目返工造成作业费用的增加和工具费用的支出。
In recent years, Wennan Oilfield with the increase in the workload of injection wells and tubing investment funds inadequate, part of the injection well used tubing for the first test pressure qualified tube, but due to the lack of tubing testing means, often due to the tubing is not dispensed Qualified packer column failure, the job site can not effectively check the tubing is qualified, so the next construction brings great difficulty. The multi-purpose inspection column can effectively determine the failure reason of the column, provides an effective basis for the next step change, provides a direct basis for whether the operation is to replace the tubing, and avoids the blind rework resulting in the increase of the operating cost and the tool expense.
