具体实施方式 detailed description
打开压力罩（11），将待测的气液分离器放入压力罩（11）内，关闭压力罩（11），通过使氮气瓶(14)中的氮气进入压力罩（11）内，提高压力，通过压力计（15）的读数控制罩内压力。通过泵（2）将储液箱（1）里的液体抽入到加热器（3）中加热，通过温度计（4）的读数控制液体的温度。液体流经液体流量计I（5）记录体积读数，再流入气液混合装置。气体从气体压缩机（9）中流入气泡发生器（8），再经过气体流量计I（7）记录体积读数，之后流入气液混合装置。气体、液体于气液混合装置（6）中混合，在泵的动力下，气液混合流体经胶皮管（10）流入位于压力罩（11）内部的气液分离器（12）。经分离后，液体由气液分离器（12）的下端流出，经液体流量计II（16）记录体积读数，流回至储液箱（1）内，完成循环。分离后的气体，由气液分离器（12）的上端流出，经气体流量计II（17）记录体积读数，流入集气瓶（18）。通过液体流量计I（5）、气体流量计I（7）和液体流量计II（16）、气体流量计II（17）的读数对比分析，可以显示出气液分离器在不同地层条件下的工作性能。同时，该装置也可以对比在同一地层条件下，不同气液分离器的工作性能。 Open the pressure cover (11), put the gas-liquid separator to be tested into the pressure cover (11), close the pressure cover (11), and let the nitrogen in the nitrogen cylinder (14) enter the pressure cover (11), improve the Pressure, the pressure in the cover is controlled by the reading of the manometer (15). The liquid in the liquid storage tank (1) is drawn into the heater (3) by the pump (2) to be heated, and the temperature of the liquid is controlled by the reading of the thermometer (4). The liquid flows through the liquid flow meter I (5) to record the volume reading, and then flows into the gas-liquid mixing device. The gas flows into the bubble generator (8) from the gas compressor (9), then passes through the gas flow meter I (7) to record the volume reading, and then flows into the gas-liquid mixing device. Gas and liquid are mixed in the gas-liquid mixing device (6). Under the power of the pump, the gas-liquid mixed fluid flows into the gas-liquid separator (12) inside the pressure cover (11) through the rubber tube (10). After separation, the liquid flows out from the lower end of the gas-liquid separator (12), records the volume reading through the liquid flow meter II (16), and flows back into the liquid storage tank (1) to complete the cycle. The separated gas flows out from the upper end of the gas-liquid separator (12), records the volume reading through the gas flow meter II (17), and flows into the gas collecting bottle (18). Through the comparative analysis of the readings of liquid flowmeter I (5), gas flowmeter I (7) and liquid flowmeter II (16), gas flowmeter II (17), it can be shown that the gas-liquid separator works under different formation conditions performance. At the same time, the device can also compare the performance of different gas-liquid separators under the same formation conditions.
