V锥流量计在智能气举阀中的应用
|
摘要
为解决井下气体流量测试难题,将V锥流量计置于智能气举阀中,对气体流量进行测试。为避免井下气体排量波动对流量计的损坏,设计了V锥缓冲装置。通过有限元分析及试验方法对V锥等效直径比进行模拟分析及优化试验。研究结果表明:V锥流量计的测试精度和V锥与流道的等效直径比β密切相关;当锥体最大节流直径为23. 5 mm,可以得到适合智能气举阀的最佳等效直径比β=0. 341;当气举阀的流量为10～40 m~3/h时,测试误差小于1. 000%,能够满足井下测试需求。V锥流量计在智能气举阀的成功应用为油气同采井提供了技术保障,对于提高该类井的举升效率和最终采收率具有重要意义。
In order to solve the difficulties in the process of downhole gas flow test,the V-cone flowmeter was placed in an intelligent gas lift valve to test the gas flow. In order to avoid damage to the flowmeter by the fluctuation of downhole gas displacement,a V-cone buffer device was designed. The finite element analysis and test method were used to simulate and optimize the equivalent diameter ratio β of V cone. The research results show that the test accuracy of the V-cone flowmeter is closely related to the equivalent diameter ratio of V-cone and flow channel.When the maximum throttling diameter of the cone is 23. 5 mm,the optimal equivalent diameter ratio( β = 0. 341)suitable for the intelligent gas lift valve can be obtained. When the flow rate of the gas lift valve is in the range of10 ～ 40 m~3/h,the test error is less than 1. 000%,which can satisfy the needs of downhole test. The successful application of the V-cone flowmeter in the intelligent gas lift valve provides technical support for oil and gas production wells,and is of great significance for improving the lift efficiency and ultimate recovery rate of such wells.
