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 15 0 8× 10 4t。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 2 8口实施套管修复 ,修复成功率达 92 .9% ,恢复控制储量达 12 0 .7× 10 4t。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 oilfields extended, the technical status of oil and gas wells has become worse year by year. At present, Wenliu oil well has about 41.9% of the total wells in the wells in question, with a loss control reserve of 15 0 × 104t. In view of the above situation, the introduction of the eight-arm magnetic combination logging technology, which combines high performance, multi-parameter, selection and combination of advanced and practical magnetic logging in one, the oil casing to be monitored. 42 wells were drilled by this technique and 28 of them were cased. The success rate of repairing was 92.9%, and the recovery control reserve was 127.0 × 104t. The application of this technology not only provides a guarantee for the accuracy of the scheme and the efficiency of the measures, but also provides a basis for understanding the reasons for the deteriorating well conditions.
