声波测井技术研究进展

Progress in Acoustic Well Logging Technology

以声波测井换能器技术的变化为主线,分析了声波测井技术的进展以及我国在该技术领域内取得的进步。单极子声波测井技术已经成为我国成熟的声波测井技术,包括非对称声源技术在内的多极子声波测井技术已经进入产业化进程。以井下声波的定向辐射和定向接收为最主要特征的相控声波测井技术是正在研发的新一代声波测井技术,我国在此领域已经取得显著突破。

The changing of acoustic transducer structure and vibrating mode cause advancement and great evolution of acoustic well logging technology both for the wireline logging and logging while drilling（LWD）. This paper analyses the general acoustic logging technology development, progresses and the situation in China, along the acoustic transducer technology improvements. Monopole acoustic well logging technology is mature in China. Futher more, the more advanced multipole acoustic well logging technolgy in which asymmetric acoustic source is already devel- oped and brought into production as well in China. The newest generation acoustic logging, with the primary characteristics of directional acoustic radiation and directional acoustic receiving, named as acoustic phased-array well logging technology is being researched and developed. Some significant achievements are carried out in this field in China.
