随着油田开发时间的延长,油水井井下技术状况逐年变差。目前文留油田井况有问题的井约占总井数的41.9%,损失控制储量达1508×104t。针对上述情况引进了八臂磁组合测井技术,该技术集高性能、多参数、选择组合及先进实用的磁测井于一体,对石油套管进行监测。应用该技术先后测井42口,对其中28口实施套管修复,修复成功率达92.9%,恢复控制储量达120.7×104t。该技术的应用不仅为方案的准确率和措施的有效率提供了保障,同时也为认识井况恶化的原因提供了依据。

With the development of oil fields, the downhole casing status of the oil and water well are getting bad and bad. The problem well of Wenliu Oilfield now has been become 41.9 percent in the whole well number, which control 1058×104t oil reserve. Arm at this problem, the eight arms magnetism combination logging technology has been introduced. The technology include better performance, more parameter, selected combination and advance magnetism logging, which can monitor the oil casing. With 42 wells being logged,28 wells’ casing are reconditioned, which recovered control reserve 120.7×104t and successful rate is 92.9%. The application of this technology not only provide guarantee to the project accuracy and the measure effective, but also provide foundation to the cognition of the reason in downhole casing.
