注入井系统找漏方法研究及应用

Study and Application of Methods for Detecting Leakage of Injection Well

系统分析了注入井漏失类型及特点,总结了常见注入井找漏方法和其局限性。将注入井地表井组漏失归入了注入井找漏种类之一,研究了注入井系统找漏二步走方法,指出了常见组合测井找漏方法的适用范围及缺点。找漏测试结果表明:双示踪+电磁流量组合测井在低注入井找漏效果很好。

The leakage types and the characteristics of the injection well were systematically analyzed, the common methods of leakage de- tecting and the limitations were summarized. The surface leakage of the well was attributed to the leakage of the injection well, the two-step method of leakage detecting was studied, the scope and shortcoming of common combination logging leakage detecting method were pointed out. The leakage detecting tests showed that the dual tracer combining electromagnetic flow logging was very effective in leakage detecting in low injection well.
