中文摘要:
      气举阀是气举采油关键部件,气嘴流动性能是影响气举系统效率的重要因素,通过CIPT实验的方法,优选合适的气举阀气嘴形状,结合数值模拟方法确定气嘴内部流动性形态,气嘴内部激波面产生位置和两侧物理参数变化规律,最终用实验数据与数值模拟结果对比分析。研究结果表明:文丘里气嘴注气稳定性比圆台气嘴和圆柱气嘴更稳定,文丘里气嘴的临界流量对应压力比为0.92,圆台气嘴的临界流量对应压力比为0.82,圆柱气嘴的临界流量对应压力比为0.78,;在高压试验条件中,气举阀气嘴中会产生激波面,经过激波面后速度降低、压力升高,变化关系满足Hugoniot关系推导式;圆台气嘴与文丘里气嘴相比较,激波面产生的位置更靠近入口,产生的激波强度也更高。
英文摘要:
      The gas lift valve is a key component of gas lift production. The flow performance of the gas nozzle is an important factor affecting the efficiency of the gas lift system. The CIPT test method is adopted to optimize the shape of the gas lift valve nozzle and the numerical simulation method to determine the internal fluidity of the gas nozzle. Morphology, the position of the shock surface inside the nozzle and the change of physical parameters on both sides, and finally the experimental data and numerical simulation results are compared and analyzed. The results show that the venturi gas injection stability is more stable than that of the round table gas cylinder and the cylindrical gas nozzle. The critical flow corresponding pressure ratio of the venturi nozzle is 0.92, and the critical flow corresponding pressure ratio of the round table nozzle is 0.82. The critical flow rate of the mouth corresponds to a pressure ratio of 0.78. In the high pressure test condition, a shock surface is generated in the gas lift valve nozzle. After the shock surface, the velocity decreases and the pressure rises. The change relationship satisfies the Hugoniot relationship derivation; the round table nozzle Compared to the Venturi nozzle, the shock surface is located closer to the inlet and produces a higher shock intensity.
