摘　　要：井下气液分离是中国油田开采工作的重要研究内容。常规的井下旋流分离技术在含气量大于60%的工况下效率不高,井下气锚在入口速度过大时效率极低。为此设计了包含碟片捕集结构的整合型气液分离器,使其可以适应高入口速度和大气液比的井下气液分离作业。研究结果表明:该分离器多级碟片结构能有效捕集气相中的离散液滴,且入口速度可达10 m/s,气液比在1/1~10/1范围内均能高效分离,具有极高的应用价值。Downhole gas-liquid separation is an important research content of oilfield exploitation in China.The conventional downhole swirl separation technology is not efficient when the gas content is greater than 60%,and the efficiency of the downhole gas anchor is extremely low when the inlet velocity is too large.Therefore,this paper designs an integrated gas-liquid separator with disc capture structure,which can adapt to downhole gas-liquid separation operation with high inlet velocity and atmospheric liquid ratio.The results show that the multi-stage disc structure of the separator can effectively capture discrete droplets in the gas phase,and the inlet velocity can reach 10 m/s.The gas-liquid ratio can be efficiently separated in the range of 1/1~10/1,which has extremely high application value.
