An Innovative Design and Analysis of the Cyclone Separator for the Pumping Well

In the process of oil production, crude oil containing gas will have adverse effect on the sucker pump: Low pump efficiency caused by pump body not fully filled with liquid, the air lock formed inside the pump which fails in pumping oil and accelerated pump damage which increases the cost of production. Most commonly used gas-liquid separators currently used underground are only applied to low gas-yield wells. But for the design of oil wells with high gas-liquid rate, the travel distance of the gas anchor of such separator is too short. The results in insufficient gas storage space and low pump efficiency due to non-fully filled pump body. Therefore, the research of the downhole gas-liquid separator has both practical and economical significance. In order to solve the existing problems, the paper developed an innovative type of the downhole gas-liquid separator, which will increase the length of the storage space in the structure and enable the gas separation to have enough travel distance and sufficient storage space, which also realize multiple separation procedures and prolong the gas-oil separation process. To the innovative separator will give solutions to the low pump efficiency caused by the poor gas-liquid separation performance for high gas-liquid ratio oil wells, etc. Thus will greatly improve the separation efficiency and the pump efficiency.
