摘　　要：同心双管分层注水工艺已成为长庆油田高效注水的手段之一,但特殊的双层管柱结构给注入剖面测井带来诸多困难。为解决同心双层管柱结构注入剖面测试方法的实施难题,围绕管柱结构特点开展方法适应性分析。通过改进部分测试工艺,开展了同位素示踪技术、噪声测井技术、井温测井技术在同心双管中的注入剖面测井研究,并在井温测井中使用了分布式光纤温度测井新技术进行试验探索。测井结果表明,同位素示踪注入剖面测井技术、噪声注入剖面测井技术、井温注入剖面测井技术可以对同心双管注入情况进行有效评价,但测试效果受诸多因素的影响,而分布式光纤温度测井技术具备较好的应用前景。Concentric double-tube stratified water-flooding technology has become one of the efficient water-flooding methods in Changqing oilfield,but the special double-tube structure brings many difficulties to injection profile testing.In order to solve the difficulty of implementing the injection profile testing method under the concentric double-tube structure,the adaptability analysis of the method is carried out based on the characteristics of the pipe string structure.After improving part of the testing process,isotope tracer logging,noise logging and well temperature logging technology are respectively carried out in the concentric double-tube injection profile logging.The new technology of distributed fiber temperature logging technology is used in well temperature logging as experimental exploration.The application results show that isotope tracer injection profile logging technology,noise injection profile logging technology and temperature injection profile logging technology can effectively evaluate the situation of concentric double pipe injection,but the test effect is affected by many factors.Distributed fiber temperature logging technology has a relatively good application prospect.
