摘要:
为解决天然气开采过程中气井的积液问题，提出了一种基于经典拉瓦尔喷管结构的激波雾化喷管，该结构的型线可进一步提升携液气流速度，加强雾化排液效果。通过对第1代喷嘴结构型线的重新优化，设计出第2代激波雾化喷嘴，并应用CFD数值方法对新旧两种结构雾化器在不同安放深度下的雾化携液能力进行了对比分析。结果显示，优化后的拉瓦尔喷管结构相比之前的结构压损更小，对流经的介质具有一定的提速作用，取得了较好的现场应用效果。第2代激波雾化喷嘴较好地解决了天然气开采过程中气井的积液问题，对气井排液增产提供帮助。
Abstract:
In order to solve the problem of fluid accumulation in gas wells during natural gas extraction, a shock wave atomization nozzle based on the classical Laval nozzle structure was proposed. However, changing the structural profile of the Laval nozzle would cause changes in the shape of the flow path, which would further affect the acceleration ability of the gas flow and eventually affect the effect of shock wave atomization of fluid accumulation. After optimization of the Laval nozzle structure profile, the 2nd generation excited wave atomization nozzle was designed, and the liquidcarrying capacity of the new and old structure atomizers was analyzed by CFD method at different placement depths. The results show that the optimized Laval nozzle structure has lower flow pressure loss and improved speedup effect compared with the previous structure, and it has achieved better field application results. The 2nd generation shock wave atomization nozzle can better solve the accumulation of liquid in gas wells during natural gas production, and help to drain liquid from gas wells to increase production.
