摘要
The paper describes the gas lifted well performance evaluation ability based on operational parameters' fluctuations analysis. Experimental laboratory research showed that the optimum gas-liquid lift performance correlates with minimal fluctuation of flowrate and pressures. Also, trials in the "Neft Dashlary" oilfield were conducted. Gas lifted well's flowing tubing head pressure fluctuations were evaluated at different lift gas injection rates - below, above, and at the optimum gas injection rates. The results of field trials show that at optimum gas lifter well performance, the tubing head pressure fluctuation amplitude reduction and frequency increase is observed. This is in line with theoretical prediction and lab experiments conducted. It is shown that gas lifted and naturally flowing wells' performance quick evaluation is doable during normal operation. The introduced method allows timely detection of well performance deviation from optimal. Necessary measures can be taken to optimize the wells without conducting additional surveillance.
