对凝析气井的流体取样,是分析判断凝析油气藏的重要手段。首先要准备好取样井,对不符合取样井条件的需要对其进行调整;其次是选择合适的取样方法,通常采用的有分离器取样方法,对于油样取样有排液取油法和排气取油法,对于气样取样有抽空取气法、气样冲洗取气法和排液取气法。最后是对取到的样品(油样和气样)进行质量检查。
Fluid sampling of condensate gas wells is an important means of analyzing and judging condensate reservoirs. First of all, we should prepare the sampling well and adjust it if it does not meet the requirements of the sampling well. Secondly, select the appropriate sampling method, usually with the separator sampling method. For the sampling of the oil sample, there is drainage and oil extraction and exhaust Take the oil method, the gas sampling for taking the time to take gas method, sample gas flushing method and drainage gas method. Finally, the quality of the samples taken (oil samples and gas samples) is checked.
