          摘要:
          為模擬油氣井氣舉排液工藝過程,開展對油氣井全生命周期的測試和工藝試驗。介紹井下多點參數直讀監測儀通信中的程控均衡系統,系統在通信中需解決井下監測儀器非等距分布、信號大小相差大的問題,一般的信號恢復電路或模擬均衡處理很難勝任信號恢復工作; 單芯電纜上的數據需滿足高精度、高速傳輸的要求,由于傳輸速率快且等效電纜長度不同,波形失真程度也不同,各短節通信參數需要分別調節以適應正常通信需要。程控均衡系統可調節相應的參數,自動適應不同長度和類型的電纜,具有較強的抗干擾和信號識別能力,即使電纜間距不同也能調整至最佳狀態。實驗測試結果表明,程控均衡系統的可靠性和穩定性較高,通信誤碼率低于1×10-10,為現場氣井排水采氣方案的制定提供實驗依據。
          Abstract:
          Abstract: In order to simulate the gas lift and discharge process of oil and gas wells, the whole life cycle test of oil and gas wells have been carried out. This paper introduces the program-controlled equalization system for downhole multi-point direct reading monitor communication. This system needs to solve the problem of non-equidistant distribution of downhole monitoring instruments in communication, because the signal will vary greatly, so the general signal recovery circuit or analog equalization is difficult for signal recovery. In addition, the data on a single-core cable must meet the requirements for high-precision, high-speed transmission. Because the transmission rate is fast and the equivalent cable length is different, the degree of waveform distortion is also different, so the communication parameter of each short section needs to be adjusted to meet the normal communication needs. Program-controlled equalization system can adjust the corresponding parameters, automatically adapt to different lengths and types of cables, has strong anti-jamming and signal recognition capabilities, it can be adjusted to the best state even if the cable spacing is different. The experimental test shows that the reliability and stability of the program-controlled equalization system are very high, and the communication error rate is lower than 1×10-10, which provides experimental basis for the development of the gas recovery plan on-site gas wells.
