摘要

摘要: 针对研制的一种新型控压钻井节流阀，对其阀座倒角处理前后节流阀阀腔内部流场进行数值模拟，并结合理论推导及现场试验对新型节流阀的工作特性进行研究，得到开度、节流压差及流量系数等性能参数间的影响关系。结果表明：新型控压钻井节流阀能够满足节流压差随阀芯开度线性变化的控制要求；采用倒角处理的阀座能在保证控压节流特性的基础上缓解流体介质对节流阀的冲刷作用，延长控压钻井节流阀的使用寿命。

Abstract: This paper studied a choke valve for the MPD, simulated the flow field with the chamfered valve seat, combined theoretical derivation with field experiments to study the working mechanisms of the choke valve, and obtained the influence relations among opening degree, choke pressure and flow coefficient. The experimental results show that the choke valve can meet the control requirement that the pressure of the choke valve varies linearly with its opening degree and that the use of the chamfered valve seat guarantees the choke characteristics as well as mitigates the fluid medium scouring action on the choke valve, thus extending the life of the MPD choke valve.
