摘要
随着生产时间的推移 ,经过压裂改造的储层又受到污染 ,早期人工裂缝部分闭合 ,产能大幅下降。以 892 6井为例 ,通过措施前、后不稳定试井资料解释结果的对比分析 ,阐述了不稳定试井资料的应用 ,同时为此类油藏油井二次措施时机、措施类型的选择及效果评价提供了可借鉴的经验。
The fractured reservoir is contaminated again with production time pasting and it's off-take potential is greatly declined with some early stage fissure being closed. By contrasting and analyzing the back and the forth transient well test data interpretation result, the paper takes example for the well8926 and gives an application of dynamic data. Meanwhile, it provides a reference experience for choosing the fracture time and type at the second time and evaluating its result of this kind oil wells.
