Popis: In this paper, we investigate an acoustic transmission technology in Production Logging, The subsurface equipment has be installed during pump operation, the logging tools and transmission system Installed in the bottom of the pump and into the wellbore together. Raw log datas are transformed into regular coding acoustic signals that are transmitted to the wellhead along the tubing and are received by acoustic detector, the signals are recorded by a computer. Engineers analyze and interpret these signals to get the dynamic production data of the well under the current production status. It can realize the well long-term monitoring. The technology was applied in Huabei Oilfield and the transmission depth is close to 2000m. The technology can provide accurate information for development plan of oilfield. This paper also discusses the attenuation factor of acoustic in the tubing and the design principle of the technology.
