The experiment tested the compatibility of methanol and formation water,the saturated vapor pressure and the salinity changed when injecting methanol into formation water. In long core experiment,two back pressure valves were applied to establish the retrograde gas condensate saturation dynamically.
实验测试了甲醇与地层水的配伍性、甲醇注入后地层水的饱和蒸气压和矿化度变化;利用RUSKA长岩心驱替实验设备,使用2个回压阀动态建立反凝析油饱和度,完成了先注甲醇段塞解除水锁,然后注干气吞吐的长岩心实验,测试了注甲醇前后的相对渗透率变化和注入压差的变化。

岩心实验表明，该堵剂具有强度高，抗盐性和热稳定性好，易解堵等显著特点。
Rock core experiments indicate that the plugging agent has some outstanding characteristics, such as, high intensity, good salt resistance and heat steadiness and easiness of being plugging solved.
注气可使凝析气露点有所升高，长岩心实验表明保持压力越高凝析油采收率越高。
Gas injection may make dew point of condensate gas increase. The long-core experiments show that the higher the pressure upkeep is, the higher condensate oil recovery is.
