介绍了对开采低渗透油藏 (层 )的虹吸尾管管柱的理论研究、管柱结构、工艺特点等 ,提出由于产能低 ,现有的泵抽举升管柱对此类油藏的开采十分不利。通过研究表明 ,采用虹吸尾管结构管柱 ,可减少流体通过的压力损失 ,提高泵的吸入压力、入泵液速度及脉冲解堵等功能。实践证明该结构管柱可恢复油井生产或提高油井的产量。 The theoretical research, column structure and technological characteristics of the siphon tail pipe string for the production of low permeability reservoirs (layers) are introduced. Due to the low productivity, the existing pumping pumping riser string has been proposed to exploit this type of reservoir Very unfavorable. The research shows that the use of siphon tail pipe structure can reduce the pressure loss of fluid through to improve the pump suction pressure into the pump speed and pulse plugging and other functions. Practice has proved that the structural columns can resume well production or improve well production.
