油管串声波通信研究与验证

油田开发过程中,为了通过地面控制每个油层的注水量,提出以注水井油管串作为传输介质传输控制信息来控制每个油层的注水阀门,实现注水量控制.利用瞬态波形分析方法建立了油管串信道模型,讨论了节箍对声传播的影响.结合注水井的实际结构,分析了声波在注水井油管串中的传播特性,实地实验结果验证了声波作为信号载波进行数据传输的可行性.

Research and verify of acoustic communication in the oil pipe strings

In the exploiting process,to control the volume of water injected into the oil layer at ground,the oil pipe strings are proposed as transmission medium of contorl information.An idealized oil pipe strings model is built by transient waveform analysis method,while the impact of section hoop on acoustic communication is also given.Based on the real constructure of the injection wells,propagation of acoustic communication is introduced.The experiment results verify the feasibility of acoustic communication.
