摘要

柱塞密封作为钻井泥浆泵的关键部件,在低渗透砂岩油藏改造和非常规油藏开发中经常出现密封失效等问题,进而导致钻井泥浆泵效率低下,甚至存在较大的安全隐患。在此基础上,设计了7000型压裂柱塞泵液压头三级密封装置,并对其密封性能进行了分析。探讨了液压头不同工作载荷和轴向预紧力对密封圈接触力和密封圈内应力分布的影响,证实了压裂柱塞泵三级密封的密封效果。结果表明,三个橡胶圈的峰值应力和峰值接触压力随着液压头工作载荷的增加而增加;三个橡胶环在安装过程中的峰值应力和峰值接触应力随着安装预紧力的增加而增加。但等效应力峰值和接触应力峰值与工作流体载荷作用下的流体载荷直接相关;在不同的工作流体压力下,橡胶在系统密封过程中的最大接触力大于系统工作介质的接触力。通过内部压力,三个密封橡胶圈可以依次发挥不同程度的密封作用,增加密封体的总寿命。

Design of three-stage sealing structure and investigation of sealing performance for 7000 fracturing plunger pump
As a key component of the drilling mud pump, the plunger seal often has problems such as seal failure in reconstruction of low-permeability sandstone reservoirs and the development of unconventional reservoirs, which, in turn, leads to low efficiency of drilling mud pumps and even great potential safety hazard. Based on this, this paper designs a three-stage sealing device at the hydraulic head for the 7000 fracturing plunger pump, and analyzes the sealing performance of the system. The effects of different working loads of the hydraulic head and axial pre-tightening force on the contact force of the seal ring and the stress distribution in the seal ring are explored, and the sealing effect of the three-stage seal of the fracturing plunger pump is confirmed. The results show that the peak stress and the peak contact pressure of the three rubber rings increases with the increasing of the working load of the hydraulic head; the peak stress and the peak contact stress of the three rubber rings during the installation process increase with the increase of the installation pre-tightening force. But the equivalent stress peak and the contact stress peak are directly related the fluid load under the action of the working fluid load; the maximum contact force of the rubber during the sealing process of the system is greater than that of the system working medium under different working fluid pressures. With internal pressure, the three sealing rubber rings can play a sealing role to varying degrees in sequence, and increasing the total life of the sealing body.
