摘要： In order to address the above noted problems, embodiments of the present invention use distributed acoustic sensing to monitor the fluid level in an ESP activated well so as to monitor the condition and performance of the ESP. Embodiments of the invention use the ESP as an acoustic source in order to monitor the annulus fluid level within the well and to monitor the frequency of the ESP. Additionally, embodiments of the present invention may use distributed acoustic sensing to monitor the flow rates of the production fluid above and below the ESP to determine the pump's efficiency. In particular, some embodiments utilize one or more optical fibers to measure the acoustic waves generated by the ESP, wherein the fiber cabling has already been deployed along the length of the well. As such, the present invention is a non-invasive, in-situ method for monitoring the condition and performance of an ESP.

摘要翻译： 为了解决上述问题，本发明的实施例使用分布式声学感测来监测ESP激活的井中的液位，以便监测ESP的状况和性能。 本发明的实施例使用ESP作为声源，以便监测井内的环状液体水平并监测ESP的频率。 此外，本发明的实施例可以使用分布式声学感测来监测ESP上方和下方的生产流体的流量，以确定泵的效率。 特别地，一些实施例利用一根或多根光纤来测量由ESP产生的声波，其中光纤布线已沿着该孔的长度展开。 因此，本发明是用于监测ESP的状况和性能的非侵入式原位方法。
