能谱水流测井适应性分析与工程应用

塔里木轮南油田经过多年的注水开发，常规同位素测井存在沾污、沉淀、污染等问题，且受黏度、管柱、大孔道地层的影响，达不到注水动态监测的要求。能谱水流测井技术，可以克服以上问题，在油田得到广泛推广应用。首先简要介绍能谱水流测井技术的原理，其次分析能谱水流测井技术的适应性，最后重点从检测套管破损情况、封隔器是否失效和确定水窜位置三个方面介绍其在工程上的应用。能谱水流测井技术能够实现一些常规测井不能实现的功能，为油田注水井注入剖面及油水井窜槽情况分析提供了准确的信息，对油田生产有着重要的现实意义。

Adaptability Analysis and Engineering Application of Spectra Water Flow Logging Technology

Conventional isotope logging conducted in the wells of Lunnan Oilfield in Tarim where the development of oil by the means of water-flooding have been taken for many years encounter the contamination, sedimentation, pollution and other problems. It is very difficult to dynamically monitor the injecting water due to the influence of viscosity, pipe string and macropore formation. Spectra water flow logging technology has been widely used in some oil fields because it can overcome the above problems. This paper begins with a brief introduction to the principles of spectra water flow logging technology, and followed by the adaptability analysis of this technology. Finally, this paper introduces its engineering application from three aspects: detecting the damages of casing, identifying the effectiveness of packers and locating water channeling point. Spectra flow logging can achieve some goals that cannot be fulfilled by the conventional logging, and is practically important to the development of the oilfield.
