摘要:

在油井作业过程中,无线通讯技术可以解决油井井下参数传输中存在的误码率高、实时性差等问题,如何选择声波特征频率以及探究声波在油管柱中的衰减度已成为近年来研究的热点。针对声波信号沿金属管壁传输衰减特性展开研究,并建立了通讯模型,在此基础上量化声波衰减规律,结合Comsol波形仿真软件验证了所建立的通讯模型和特征频率选取的正确性。结果表明,该方法可以有效传输声波信号,为油井远程无线声波通讯技术提供了最佳频率选取方案。

Abstract:

In the process of oil well operation, wireless communication technology can solve the problems such as high bit error rate and poor real?time performance in the down?hole parameter transmission. How to choose the characteristic frequency of sound wave and explore the attenuation degree of sound wave in the oil string have become the research hotspots in recent years. In this paper, the attenuation characteristics of acoustic signals transmitted along metal tube walls were studied, a communication model was established, and the attenuation law of acoustic signals was quantified on this basis. Combined with Comsol waveform simulation software, the correctness of communication theory model and characteristic frequency selection was verified. The results show that this method can effectively transmit acoustic signals and provide an optimal frequency selection scheme for oil well remote wireless communication technology.

Key words: Wireless acoustic communication, Acoustic attenuation, Comsol simulation software, Tubing string sound transmission, Characteristic frequency selection
