为了提高有水气井井下节流工艺技术水平,在930m模拟实验井上,配套了两相嘴流测试装置,开展了气水两相嘴流实验研究,对气液两相嘴流现象及特点进行了观察和分析。获得30多组较宽范围的实验数据,在其基础上对机理模型、Gilbert三参数类型、Gilbert四参数类型、Omana类型共16个气液两相节流嘴流模型进行了综合评价。经对比分析,对于有水气井井下节流参数嘴径设计,临界流条件下推荐使用Elibaly发展的Gilbert类型三参数关系式,亚临界流条件下推荐使用Sachdeva模型。
In order to improve the technological level of downhole technology for water and gas wells, a two-phase nozzle flow test device was equipped on the 930m simulated experiment well to carry out experimental study on gas-water two-phase nozzle flow. The phenomenon and characteristics of gas-liquid two- Observation and analysis. A total of more than 30 groups of experimental data were obtained. Based on these, a total of 16 gas-liquid two-phase flow models were evaluated, including the mechanism model, the Gilbert three-parameter type, the Gilbert four-parameter type and the Omana type. Through comparative analysis, for the design of downhole throttle parameters of water and gas wells, the Gilbert type three-parameter relation developed by Elibaly is recommended under the critical flow conditions, and the Sachdeva model is recommended under subcritical flow conditions.
