摘　　要：通过对井下气液分离系统的研究,设计出了适合井下气液分离的排气装置。根据排气装置的结构参数设计出实验室模拟装置,并进行了全面的室内试验和测试,筛选出了排气装置的浮子类型和尺寸参数,研究了浮子种类、参数及不同介质对排气装置开启压力的影响。试验结果表明,所设计的排气装置在气体通过时的开启压力明显小于液体通过时的开启压力,基本达到了井下气液分离排气装置的性能要求,并可根据井下不同压差需求设计满足要求的排气装置。The gas drainage equipment of downhole gas/water separation was developed after studying the downhole gas/water separation system. Based on the configuration parameter of gas drainage equipment, experimental simulation equipment was designed. Through lab experimental and testing, the type and dimension of floater of gas drainage equipment was determined and the different influence on unlock pressure was studied. The experimental results indicated that the unlocked pressure of gas is obviously less than that of liquid and could change the parameter to carry out the different pressure, which meet the performance requirement of gas drainage equipment.
