| 摘 要： | 为了提高声波全波测井资料在生产中的实际应用效果,本文开发了包括杂波区“归零技术”、频谱分析应用技术、滤波技术等在内的声波全波资料预处理技术。快速专家辅助计算机自动拾取信息波初至的方法解决了信号弱的软地层信息波的初至拾取问题。在充分分析了气层在声波全波测井及常规测井不同信息特征的基础上,本文提出了天然气综合判别指数法,利用此方法比较容易识别含气层。通过实例分析,得到了较好的效果。

| Abstract: | In order to improve the applied effects of full wave acoustic logging data in production,the paper developed the preprocessing techniques of full wave acoustic logging data including "positioning zero technique"in disordered wave zone,spectrum analysis and application and filtering technique.The method for automatically detecting first break of informational wave by fast specialist aided computer solved the problem of detecting first break of informational wave in soft formation having weak signal.The paper also analyzed the feature that the gas bearing formation has different information in full wave acoustic logging data and ordinary logging data,forming integrative judgement index of natural gas and making the characteristics of gas bearing formation clearer.The real cases showed that the method has gained good results. |
